Sri Lanka dengue count tops 150,000 just before National Mosquito Control Week

September 9, 2017
As the Sri Lanka Health Ministry outlines plans to launch National Mosquito Control Week later this month, the total case count in the country has topped 150,000 cases, more than three times the numbers reported in 2016 at this time.
Although there is a significant drop in the number of dengue patients now, health officials warns the risk remains with the north-east monsoon rains.
According to the National Dengue Prevention Unit earlier 10,000 patients per week have been recorded and it has reduced to 1,500 per week currently.
The threat of spreading dengue still exists in Colombo, Gampaha, Kalutara, Kurunegala, Puttalam, Ratnapura, Kegalle, Galle, Matara, Jaffna, Batticaloa, Trincomalee, Kalmunai and Kandy districts, according to health officials.
Through September 8, 150,407 cases have been reported with the most seen in Colombo, Gampaha and Kandy.

Dengue epidemic waning in Sri Lanka, University of Jaffna Science Faculty closed until September

August 25, 2017
The number of dengue fever cases continue to climb in Sri Lanka, but a much slower pace in the month of August.
Sri Lanka health officials reported more than 40,000 cases in July and only 16,000 through Aug. 25.
“Dengue cases have dropped in August and special dengue wards in hospitals are closing,” Health Minister Rajitha Senaratne said.
Despite the minister’s statement and the official numbers from the Ministry of Health’s Epidemiological Unit, some question the true extent of the epidemic.
According to an Economy Next report, a check at some of Sri Lanka’s private hospitals where dengue antigen tests are performed showed that there is currently no requirement to report positive results to the health ministry.
Through Friday, Sri Lanka has officially reported 144,052 cases and as of Aug. 3, 327 people have died.
At the University of Jaffna, at least nine students of the Science Faculty have been stricken with dengue and hospitalized, and one death in a student was reported, prompting closure until Sept. 4, according to a Hiru News report this week.

Sri Lanka dengue update: More than 20,000 cases in Gampaha

July 30, 2017
In the month of July, Sri Lankan health authorities have reported more than 27,000 dengue fever cases, almost triple the number of cases reported in July 2016 (10,715) bringing the 2017 year-to-date total to 114,215, including more than 300 deaths.
In addition to the Colombo area, Gampaha has also reported greater than 20,000 cases. Approximately 45.04% of dengue cases were reported from the Western province.

Sri Lanka Red Cross: ‘The size of this dengue outbreak is unprecedented’

July 24, 2017
With the number of dengue fever cases topping 105,000 cases and 300 deaths so far in 2017, the Sri Lanka Red Cross Society and the International Federation of Red Cross and Red Crescent Societies (IFRC) are rapidly scaling up emergency assistance to help contain the country’s worst-ever outbreak of the mosquito-borne viral disease.
Dengue patients are streaming into overcrowded hospitals that are stretched beyond capacity and struggling to cope, particularly in the country’s hardest hit Western Province.
“Dengue is endemic here, but one reason for the dramatic rise in cases is that the virus currently spreading has evolved and people lack the immunity to fight off the new strain,” says Dr Novil Wijesekara, Head of Health at the Sri Lanka Red Cross.
Compounding the crisis, recent monsoon rains and floods have left pools of stagnant water and rotting rain-soaked trash—ideal breeding sites for mosquitoes. Ongoing downpours and worsening sanitation conditions raise concerns the disease will continue to spread.
Teams of Sri Lanka Red Cross volunteers have been supporting a large-scale government effort to stem the outbreak—providing patient care at hospitals and going door-to-door with public health inspectors to raise awareness about the disease, its symptoms and how to prevent its spread. Volunteers have also been helping authorities to identify and clean sites where mosquitoes are breeding.
Today, IFRC released new Disaster Relief Emergency Funds to the Sri Lanka Red Cross to vastly expand the response over the next six months, aiming to assist 307,000 people in the districts of Colombo, Gampaha and Kalutara where dengue is rampant.

Dengue updates for Vietnam and Sri Lanka

August 19, 2017


The number of dengue fever cases in Vietnam spiked by some 10,000 cases in the past week. Tran Đac Phu, head of the ministry’s preventive medicine department, said the country had recorded 90,626 dengue cases since the beginning of 2017, a year-on-year rise of 67.8 per cent, including 24 fatalities, local media reports.
This is up by about 10,000 since the last total case count was released on Aug. 3.
The outbreak is stretching the country’s medical system as more than 78,000 of the cases required hospitalization.
In the capital city of Hanoi, there has been 17,027 recorded dengue cases, seven of whom died since the beginning of the year.

Sri Lanka

Since the beginning of the year, Sri Lanka has reported 137,279 suspected dengue cases and more than 300 deaths. Approximately 44.53% of dengue cases were reported from the Western province.
This compares with approximately 39,000 cases reported in January-August 2016 and 55,150 cases during the entire year.

Dengue fever – Sri Lanka

Disease Outbreak News- by WHO
19 July 2017
From 1 January to 7 July 2017, the Epidemiology Unit of the Ministry of Health (MoH) Sri Lanka reported 80 732 dengue fever cases, including 215 deaths. This is a 4.3 fold higher than the average number of cases for the same period between 2010 and 2016, and the monthly number of cases exceeds the mean plus three standard deviations for each of the past six months. Based on sentinel site surveillance for the past seven years the expected peak months of May to July coincides with the south-western monsoon which commences in late April.
Approximately 43% of the dengue fever cases were reported from the Western Province and the most affected area with the highest number of reported cases is Colombo District (18 186) followed by Gampaha (12 121), Kurunegala (4889), Kalutara (4589), Batticaloa (3946), Ratnapura (3898), and Kandy (3853). Preliminary laboratory results have identified Dengue virus serotype 2 (DENV-2) as the circulating strain in this outbreak. Although all four DENV have been co-circulating in Sri Lanka for more than 30 years and DENV-2 has been infrequently detected since 2009.
The current dengue fever outbreak occurs in a context of massive heavy rains and flooding and is currently affecting 15 out of 25 districts in Sri Lanka where almost 600 000 people have been affected. Heavy monsoon rains, public failure to clear rain-soaked garbage, standing water pools and other potential breeding grounds for mosquito larvae attribute to the higher number of cases reported in urban and suburban areas.

Dengue fever cases up by 33 percent in Vietnam

Through the first seven months of the year, Vietnam has seen 80,555 dengue fever cases, an increase of 33.5 percent compared the same period in 2016.
Health officials also reported five additional dengue-related fatalities, bringing the total to 22.
Majority of cases were reported from the South (59 percent). A sharp increase in the number of reported cases has been observed in the North (almost 25 times compared to same period last year) especially from Ha Noi with more than 15,000 cases.
In Hanoi, the outbreak has struck 12 districts, including Dong Da, Hoang Mai, Hai Ba Trung, Thanh Xuan, Ha Dong, Cau Giay, Thanh Tri, Ba Dinh, Nam Tu Liem, Thanh Oai, Bac Tu Liem and Hoai Duc.
In Ho Chi Minh City, Center for Preventive Medicine said that in the last seven weeks, dengue fever has shown signs of slowing down.

Dengue in the Philippines: Cases down 37%, Testing to be available at the malls

August 12, 2017
After reporting more than 200,000 dengue fever cases in each of the last two years, some great news is being reported by Philippine public health officials. During the first six months of 2017, officials report a total of 43,770 dengue cases nationwide. This number is 36.8 percent lower (25,527) compared to the same time period in 2016.
In addition, 250 deaths were reported. This is 84 fatalities less than the 334 deaths recorded in the same period last year.
All regions of the archipelago reported decreases in the mosquito borne viral disease except the National Capital Region.
Last month, officials with Healthway Medical, a network of mall-based medical clinics and biotechnology firm Philab Industries, manufacturer of the LABit DX Dengue NS1 Ag test, partnered to provide dengue testing at Healthway Medical Clinics.
This partnership would enable Healthway to expand its businesses, to an early screening of dengue infection and advocate for a better understanding of the disease towards a proactive health and lifestyle.
LABit Dengue NS1 Ag device is an immuno-chromatographic assay used for the rapid detection of dengue virus NS1 antigen in human blood. Dengue-specific antibodies complexed with gold conjugate are placed in the conjugate pad in the test region, while anti-dengue NS1 antibodies are immobilized on the membrane. When a dengue antigen positive specimen is loaded into the sample injection point, the liquid sample migrates to the test region via lateral flow movement then antigen is captured by immobilized anti-dengue NS1 antibodies on the membrane. The antigen reacts with dengue-specific antibodies complexed with gold conjugate to make a visible band in the test line.

Dengue: Air travel linked to spread in Asia

August 4, 2017
While the incidences of many other infectious diseases have declined over the past decade, the number of cases and outbreaks of dengue virus have continued to increase. The spread of dengue to new areas is likely due in large part to trends in air travel, researchers now report in PLOS Neglected Tropical Diseases.
Dengue virus affects as estimated 390 million people around the globe each year, and can cause symptoms ranging from a mild fever and headache to severe low blood pressure. The virus has mostly caused disease in tropical and subtropical areas of the world, but a 2014 outbreak in Japan broke that pattern. Overall, the geographic area affected by dengue has been growing in recent years.
In the new work, Huaiyu Tian and Bing Xu, both of Beijing Normal University, China, together with colleagues from the University of Oxford and elsewhere analyzed the spread of dengue viruses in Asia from 1956 to 2015. They used 2,202 genetic sequences of dengue viruses, collected in 20 countries or regions of Asia over the 59 years, to determine how different strains were related. They also investigated trends in air travel, maritime mobility, migration, and socio-economics to determine what factors impact the spread of dengue.
The spread of three different dengue virus serotypes, DENV-1, -2, and -3, is associated with air traffic moreso than any other factors, the data revealed. Air traffic hubs such as Thailand and India, the researchers found, help seed dengue epidemics, while China, Cambodia, Indonesia, and Singapore help diffuse the virus to other Asian countries.
“Future trends in global mobility could potentially accelerate the appearance and diffusion of DENV worldwide,” the researchers say. “Prevention and control of dengue epidemics requires a better understanding of its mode of geographic dissemination, especially for countries in the tropics.”

Malaysia: Dengue most prevalent infectious disease

August 2, 2017
Through August 1, Malaysia health authorities have reported 58,327 dengue fever cases, including 131 deaths.
Selangor state has reported the most cases, accounting for 55 percent of the country total. Kuala Lumpur has reported more than 5,500 cases.
Nationally, dengue fever is by far the most prevalent infectious disease in Malaysia. As the Sun Daily reports,  there are 328.3 dengue cases per 100,000 population. This is followed by hand, foot, and mouth disease (152.25), leptospirosis (17.12), hepatitis B (12.60), and HIV (11.00).
Health Minister Datuk Seri Dr S. Subramaniam said, “In order to address the incidence of dengue fever brought by Aedes mosquitoes, the ministry has implemented various preventive and control measures including using a web-based real time monitoring system, namely, eDengue and a dengue epidemic management system (SPWD) to enhance surveillance on case locality and dengue epidemic.”

Philippines report more than 200,000 dengue cases for a 2nd year

February 9, 2017 
The Philippines has been one of southeast Asia’s dengue hotspots in recent years and according to the latest figures from the Department of Health-Epidemiology Bureau (DOH-EB), the archipelago recorded more than 200,000 dengue cases for the second year in a row.
Health officials report a total of 211,108 dengue cases in 2016, slightly down from 2015 when 213,930 cases were recorded.
Regions of the country that saw the most dengue in 2016 include the Central Visayas (Cebu), the Western Visayas (Iloilo) and CALABARZON ( Cavite, Laguna, Batangas, Rizal, and Quezon).
Last April, the DOH instituted The Dengue School-Based Immunization program and hundreds of thousands of schoolchildren were vaccinated with the vaccine, Dengvaxia. The Philippines was the first country to roll out a dengue vaccination program.

Philippines Zika tally now 57, including seven pregnant women

February 6, 2017
As of February 2, 2017, a total of 57 Zika cases were reported in the country. There were 38 (67%) females and 19 (33%) males. Age ranged from 7 years-59 years (median 32 years). There were no deaths. These were detected in the following areas: National Capital Region – 20 cases (35%), CALABARZON – 18 cases (32%), Western Visayas – 15 cases (26%), Central Luzon – 2 cases (4%) and Central Visayas – 2 cases (4%).
Of 57 cases, 7 were confirmed Zika pregnant cases. Age ranged from 16 years to 32 years. Three came from NCR and 2 each from CALABARZON and CENTRAL VISAYAS. One case 16-year-old from Las Piñas) already gave birth to a baby boy at full term without microcephaly. Another case (32 year old from Central Visayas) had spontaneous abortion at 9 weeks of pregnancy. The rest are being closely monitored.
The Department of Health (DOH) is currently verifying a report that a mother and her full term, newborn baby girl in Western Visayas, were screened positive for Zika virus antibodies using a rapid diagnostic test, which is not confirmatory. The mother did not manifest any symptoms of Zika virus throughout her pregnancy. She gave birth by normal spontaneous vaginal delivery. However, upon the birth of the child, it was observed that the size of the baby’s head is smaller than the usual (microcephaly). The baby was also born with encephalocoele, rare type of birth defect of the neural tube that affects the brain, in the area between her eyes.
“Samples from mother and the baby were sent to the Research Institute for Tropical Medicine (RITM) and will be subjected to a confirmatory test on Zika virus using Real-Time Polymerase Chain Reaction (RT PCR),” Health Secretary Paulyn Jean B. Rosell-Ubial explained.
The health chief added that Zika infection is asymptomatic in 80% of cases and most of the time the disease is self-limiting. However, the effect on the result of pregnancy should not be discounted. Zika virus has been linked to congenital CNS malformation like microcephaly. DOH calls on pregnant women to avoid mosquito bites especially during day time. Insect repellents are safe for regular application. For those with fever, rash, and conjunctivitis, submit yourself for consultation.
Zika viral disease, caused by Zika virus, is characterized by fever, rash, and conjunctivitis. Other symptoms are joint pain, muscle pain, headache, and vomiting. The illness is usually mild with symptoms lasting for a week in most cases and not requiring hospitalization.
Zika virus is usually transmitted through the bite of infected female Aedes aegypti mosquitoes, the same mosquitoes that transmit Dengue and Chikungunya viruses. There have been reports that the virus can be transmitted through sexual contact.
The symptoms of Zika virus disease can be treated with common pain and fever relief medicines, rest, and plenty of water intake. Pregnant women who develop illness should seek advice of doctors before taking any medicine. If symptoms persist, patients are advised to consult the nearest health facility. Currently, there is no available vaccine to prevent Zika virus infection.
“It is very important to search and destroy the potential breeding sites in order to prevent the spread of Aedes mosquitoes that serve as vector of the virus. We reiterate that cleanliness is still the key against mosquito-borne diseases. The public is reminded to be vigilant and pre-cautious in eliminating mosquito breeding places through the ‘4S campaign’. The 4S means Search & destroy mosquito breeding places, use Self-protection measures, Seek early consultation for fever lasting more than 2 days, and Say yes to fogging ONLY when there is an impending outbreak,” Secretary Ubial concluded.

Vietnam dengue cases top 110,000 in 2016, up nearly 40 percent

January 18, 2017
The number of dengue fever cases reported in Vietnam during the first eleven months of 2016, reveal a 38 percent increase in cases compared to the same period in 2015.
As of 30 November 2016, there were 110,854 cases of dengue including 42 deaths reported in Vietnam. 42 dengue-related fatalities have been reported.
Compared to the median for 2011-2015, the cumulative number of cases increased by 79.9 percent.
In neighboring Laos,  there were 5617 cases of dengue with 10 deaths reported in Lao PDR in 2016. The number of cases is higher than in the two previous years.

Vietnam Zika news: Epidemic in Dong Nai, 1st case in Ben Tre

January 15, 2017
After reporting four Zika virus infections in Vinh Thanh Commune since end of December, the steering board of disease prevention in the southern province of Dong Nai last week announced a Zika epidemic.
Officials decided to announce epidemic to warn people of the disease and adopt measures to curb its spreading.
In the Mekong Delta province of Ben Tre, officials have reported the first case of the Zika virus in a 25-year-old woman who is 18 weeks pregnant.
Do Tan Hong, head of the province’s preventive medicine center, said because the patient lives near an industrial park crowded with migrant workers, there is a risk of the virus spreading that has to be monitored carefully.
Vietnam has reported 212 Zika virus cases since the first cases were seen last fall. The outbreak is most prominent in Ho Chi Minh City, which has 186 cases, including 12 pregnant women.

Philippines: Dengue cases ‘steady’ compared to 2015

January 4, 2017
In 2015, the Philippines reported more than 200,000 dengue fever cases and according to data from the archipelago, similar numbers may be seen in the final tally for 2016.
Through Nov. 5,  there were 176,411 suspected cases of dengue reported in 2016, including 422 deaths. This is 0.8% lower than that reported during the same period in 2015 (n=177,767).
The good news is the numbers have dropped dramatically in recent weeks and are well below alert and epidemic thresholds.
The Philippines recorded nearly 600 dengue related deaths in 2015.
The Philippines has already vaccinated hundreds of thousands of schoolchildren with the dengue vaccine, Dengvaxia since it’s roll-out in April.

Philippines FDA issues cease and desist order against Sanofi Pasteur for Dengvaxia ads

January 3, 2017 Asia
The Philippine Food and Drug Administration (FDA) has issued a Summons with Cease and Desist Order against pharmaceutical giant Sanofi Pasteur Inc. for airing television and radio advertisements of its dengue vaccine, Dengvaxia.
The airing of the advertisement is in violation of Administrative Order No. 65 s. 1989, prohibiting advertisement in any form of prescription or ethical drug.
The FDA’s Center for Drug Regulation and Research (CDRR) has monitored the airing of the advertising materials on dengue vaccination. It has also reported the unauthorized promotion of dengue vaccine in the malls.
In the Summons issued by FDA last December 13, 2016, Sanofi was directed to cease and desist from disseminating advertisements for Dengvaxia in any form of mass or social media. Sanofi was also directed to stop activities promoting and marketing the vaccine. However, as of December 15, 2016, the company has failed to comply with FDA’s directive to take down the said advertisements.
“Since Sanofi has not complied, we have issued summons directing them to cease and desist from airing the advertisements and Show Cause why they should not be penalized for violating the law.” FDA Director General Nela Charade G. Puno said.
Puno added that to ensure immediate compliance, “the FDA already sent letters to TV and Radio Stations directing them not to air the said unauthorized ads.”
Puno also said the FDA will monitor compliance by Sanofi and the stations.
“We are looking forward to their cooperation in our mandate to ensure that the public is provided only with the correct information on the food, drugs, cosmetics, and health devices that they use,” Puno pointed out.

Malaysia dengue cases top 100,000 in 2016, Dengue vaccine still not approved

January 4, 2017
In 2015,  the Southeast Asian country of Malaysia reported in excess of 120,000 dengue fever cases, including  322 dengue related fatalities. As 2016 came to a close, Malaysian health officials say the case tally has just eclipsed the 100,000 mark and the death toll is also down.
Through the 51st week of 2016, Malaysia has reported 100,028 cases and 231 deaths. Like in 2015, Selangor state accounted for about half of the country’s dengue cases with approximately 50,000 reported.
While the case total dropped a little in 2016, Malaysia still reports a significant number of dengue cases and is one of the hardest hit dengue endemic countries, and as one author critiques, Malaysia continues to rely on outmoded mosquito control techniques such as fogging.
Philip Stevens, Senior Fellow at the Institute for Democracy and Economic Affairs (IDEAS) wrote in an Op-Ed in the Star Online promoting the use of the dengue vaccine, “Why is it that 13 dengue-endemic countries in Asia and Latin America have so far approved the new vaccine (Dengvaxia) and Malaysia lags behind, despite its high burden of disease?”
In another piece in Malay Mail Online, Stevens questions the logic of the government–Deputy Health Minister Datuk Seri Dr Hilmi Yahya stated earlier this month that the government is “still doubtful of the vaccine’s effectiveness, as such there is no need to register the vaccine in the country for the time being”.
What is clear is that current approaches to mosquito control are both ineffective and costly.  In light of tighter budget lines and the availability of more cost effective methods, perhaps it is time for the Ministry of Health to take on a fresh approach to fighting dengue.

Malaysia reports additional local Zika transmission, 2nd case in Sabah

October 2, 2016
In a follow-up to reports of locally acquired, or autochthonous transmission Zika virus infection in Malaysia, the Ministry of Health reported Friday of the seventh case in a 60-year-old woman.
The woman from Kota Kinabalu, Sabah  is the second case of Sabah state.
According to the health ministry, on Sep 24, the patient developed a rash and began treatment at a private hospital the next day as an outpatient. Zika infection was confirmed via tests on blood and urine done by the Medical Research Institute (IMR) on Sep 28.
Epidemiological investigation shows the patient had no recent travel history.
For the month of September, seven Zika virus cases have been confirmed. During the month, monitoring of 163 cases that had signs and symptoms of Zika infection, tested negative for the virus.

Chikungunya outbreak declared in Cavite

October 1, 2016
The Provincial Health Office of Cavite in the Calabarzon region on Luzon island has declared an outbreak of the mosquito borne viral disease, chikungunya, after detecting 400 suspected cases, Department of Health (DOH) spokesperson Dr. Eric Tayag said Friday during a radio interview.
tayagThe 400 cases have been reported since the beginning of the year and the bulk of the cases have been reported from the municipality of Indang.
“It’s because in our records, Indang is still a hot zone but you have to understand that the data we receive are two weeks in between. Maybe they have a new report that’s why they declared an outbreak,” he said.
Tayag went on to say that the Calabarzon region (Cavite, Laguna, Batangas, Rizal and Quezon) that had the highest number of reported suspected cases of chikungunya this year.
Since 2013, chikungunya outbreaks have occurred in Antique, Bataan, and Iloilo but no deaths have been reported. The outbreaks typically coincide with dengue season.

Zika in Asia: CDC says pregnant women should postpone travel to 11 countries

September 29, 2016
The Centers for Disease Control and Prevention (CDC) posted today Zika virus-related special travel considerations for 11 Southeastern Asian countries. CDC now recommends that pregnant women should consider postponing nonessential travel to these countries because of the uncertain risk of Zika virus infection. CDC is issuing these special travel considerations so that travelers, especially pregnant women, can make informed decisions about their travel and their health.
The countries included in these considerations are Brunei, Burma (Myanmar), Cambodia, Indonesia, Laos, Malaysia, Maldives, Philippines, Thailand, Timor-Leste (East Timor), and Vietnam.
Zika virus has been present in areas of Southeast Asia for many years, and several countries have reported occasional cases or small outbreaks. Recent variations in the number of cases reported in the area have been observed. Zika virus is considered endemic in some of these countries, and many people who live there are likely immune. But US travelers to areas where Zika is endemic may not be immune to the virus and infections have occurred in travelers to Southeast Asia. 
The level of risk for Zika virus infection in these countries is unknown, but it is likely lower (but not zero) than in areas where Zika is newly introduced and spreading widely. However, because Zika virus infection during pregnancy causes severe birth defects, including microcephaly and other severe brain abnormalities, pregnant women should talk to their healthcare provider and consider postponing nonessential travel to Southeast Asia. Zika virus testing should be offered to pregnant women and considered for other people who have symptoms of Zika virus disease if they have recently traveled to Southeast Asia. 
Travelers to areas where Zika is actively spreading who have not already been infected with Zika virus can get it from mosquito bites. Mosquitoes that spread Zika bite during the day and night. There is no vaccine or medicine for Zika virus. The best way to avoid Zika virus infection is to prevent mosquito bites.  
Some travelers to areas with Zika will become infected while traveling but will not become sick until they return home and they might not have any symptoms. To help stop the spread of Zika, travelers should use insect repellent for three weeks after travel to areas with Zika to prevent mosquito bites. 
Some people who are infected do not have any symptoms. People who do have symptoms have reported fever, rash, joint pain, and red eyes. The sickness is usually mild with symptoms that last from several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika. Travelers to areas with Zika should look for symptoms or sickness after returning. If they become sick, they should tell their healthcare professional when and where they have traveled. 
CDC has received reports of Zika virus being spread through sex with sick returning travelers. Until more is known, CDC recommends that pregnant women and women trying to become pregnant take the following precautions. 
Pregnant women 
·         Should not travel to any area with a Zika travel notice and should consider postponing nonessential travel to the 11 countries in Southeast Asia listed in the newly issued considerations.
·         If you must travel to or live in one of these areas, talk to your healthcare provider first and strictly follow steps to prevent mosquito bites during your trip.
·         If you or your partner live in or travel to these areas, use condoms from start to finish every time you have sex or do not have sex during the pregnancy. Sex includes vaginal, anal, and oral sex.

Ho Chi Mihn City reports 35% increase in dengue

September 29, 2016
Officials in Ho Chi Mihn City (HCM City) say that recent increased rainfall has resulted in an increase in the mosquito population in Vietnam’s largest city and the resulting increase in dengue fever.
More than 11,300 dengue cases in the city have been reported this year, an increase of 35 per cent compared to the same period last year and the trend is expected to continue for the next several weeks as Vietnam’s peak dengue season continues through October.
According to local media, Cu Chi District is the hottest spot for dengue infections besides Hoc Mon, Binh Chanh, Thu Duc and Binh Thanh districts.
National data on dengue is slow to be revealed with the most recent being published at the end of June. As of 30 June 2016, there were 36,639 cases of dengue including 11 deaths, reported in 44 out of 63 provinces in Viet Nam. This is an increase of 184.7% from same period in 2015 and an increase of 102.7% over the 2011-2015 median.

Japan reports 1st dengue fatality since 2005

July 24, 2016
A woman from Niigata Prefecture, on the west coast of Japan’s Honshu island, has died from dengue hemorrhagic fever (DHF) after contracting the mosquito borne viral disease in the Philippines, according to the Japan Health Ministry (computer translated).
This was the first dengue related death recorded in Japan since 2005.
The woman in her 30s traveled to the Philippines from June 29 to July 15. Upon return to Japan, she saw her doctor and was subsequently admitted to the hospital with symptoms of rash, abdominal pain, vomiting, diarrhea and bleeding. She passed away on July 21.

China reports 1st Rift Valley Fever case, imported from Angola

July 24, 2016
Chinese health officials have already reported 11 imported cases of the mosquito borne viral disease, yellow fever, in people working overseas in Angola, now health officials have reported the first case of another disease that can be transmitted by mosquitoes, Rift Valley Fever (RVF), according to a CRI Online report (computer translated).
The case, the first of its kind reported in China, is reported in a 45-year-old man from Henan province in Central China’s Yellow River Valley who returned from Angola. He presented with fever, headache, joint and muscle pain last week.
On July 21, he returned to Beijing and was hospitalized in quarantine and began treatment. He was diagnosed positive for RVF virus yesterday. He is currently in critical condition.
Rift Valley Fever is mosquito-borne virus that is endemic in parts of Africa including South Africa. It primarily infects animals like sheep, cattle and goats and it can have an economic impact on a community due to the loss of livestock.
Humans get infected through contact with infected animal blood or organs. Butchering and slaughtering of animals is a primary cause of transmission to humans. Certain occupations are at a higher risk of getting Rift Valley Fever like farmers, herders and veterinarians.
It can also be transmitted to humans through mosquito bites and the bites of blood-sucking flies.
Most cases of RVF are mild and symptoms include fever, headaches and muscle pain. However, a small percentage of people can get serious disease which includes retinitis, encephalitis and a hemorrhagic fever. Fatalities happen in less than 1 percent of those infected.

Dengue in the Philippines: 57,000 cases, 248 deaths through 1st six months

July 20, 2016
Officials with Philippines Department of Health (DOH) report that the number of dengue fever cases reported from the beginning of the year through June 25 is nearly 36 percent higher than the same period in 2015 when the archipelago reported in excess of 200,000 cases.
To date,  DOH there were 57,026 dengue cases recorded nationwide, compared to 42,026 cases last year during the first six months.
In addition, dengue related fatalities are up–248 compared with 148 in 2015 during the same period.
The regions hit the hardest to date include Calabarzon with 7,463 (13.1 percent); Central Visayas, 5,783 (10.1 percent); Central Luzon, 5,586 (9.8 percent); northern Mindanao, 5,521 (9.7 percent); and Socssksargen, 4,583 (8 percent).
