Dengue fever spreads in HCMC

Although the peak season of dengue fever has not yet arrived, there is a large-scale outbreak in Ho Chi Minh City and neighboring provinces. The Ministry of Health (MoH) on March 27 has implemented the national dengue fever prevention project for the South.

The measures come on the heels of high infection rates at hospitals in the city. A lot of infant patients have been hospitalized recently. At the pediatric division of the Tropical Hospital, doctors are busy treating children with dengue fever.

The division?s head, Dr Tran Van Ngoc, said 25 infants were cured on March 27 and the division is receiving around 10 people daily.

Around 124 cases of dengue fever have been rushed to the infectious division of HCMC Pediatrics Hospital No.2 since the beginning of March, according to Dr. Vu Quang Vinh from the Planning Room.

Dr. Nguyen Dac Tho, Vice director of the Ho Chi Minh Preventive Health Department, is worried about the development of dengue fever in the city.

His department?s survey shows that 90 percent of households in the districts of Binh Thanh, 12, and 6 have many mosquitoes. Around 2,250 dengue fever cases, including one fatality, have been reported so far this year, a year-on-year increase of eight percent, according to the department?s statistics.


To prevent a possible spread of dengue fever in the upcoming rainy season, the Department of Preventive Health on March 27 convened a meeting with Southern medical agencies to implement the project.

A department representative said that the disease has had huge impact on residents? health and lives. This year, the MoH will spend VND1 billion on nationwide prevention, targeting to reduce infections by 10 percent and fatality rates compared to the average of 2003-2007.

Cases of dengue continue to rise
(31-03-2009)

HCM CITY?The number of dengue fever cases in HCM City in the first quarter of this year has increased by 8 per cent compared with the same period a year ago, according to the municipal Department of Health.

To date, the department has recorded 2,250 people hospitalised with dengue fever, one of whom died.


Many hospitals in the city have reported increasing numbers of dengue fever cases over the last several months.

Dr Tran Van Ngoc, head of the HCM City Tropical Disease Hospital?s Paediatrics A Ward, says the ward has been receiving an average of 10 dengue fever patients per day.

Dr Vu Quang Vinh, deputy head of Paediatrics Hospital No 2?s general accounting department, says that the hospital has received 124 cases so far this month.

The situation is rather serious, says Dr Nguyen Dac Tho, deputy director of the city?s Preventative Health Centre. He says a survey conducted by the centre in districts 12, 6 and Binh Thanh found disease-carrying mosquitoes in more than 90 per cent of the houses.


To discuss ways to prevent new outbreaks in the upcoming rainy season in southern provinces, the Ministry of Health?s Preventive Medicine Department held a meeting on Friday with representatives of provincial health departments on implementing the National Dengue Fever Prevention Programme.

A representative from the Preventive Medicine Department said this year, the ministry would run the National Dengue Fever Prevention Programme in all provinces and cities nationwide at a cost of more than VND91 billion (US$5.2 million).

The programme aims to reduce, by the end of this year, both the number of people infected and those dying from dengue fever by 10 per cent over the average during the 2003-07 period. ? VNS

Hot weather fails to prevent dengue outbreak in Delta

11:24' 08/04/2009 (GMT+7)

VietNamNet Bridge ? The mosquito-borne dengue fever, normally a threat during the rainy season, is occurring now in what is the peak of the dry season in the Cuu Long (Mekong) Delta, according to provincial health departments.

Can Tho Paediatrics Hospital director Le Hoang Son said the city had reported 310 cases so far this year.


But with no vaccine available yet against the disease, spraying chemicals and keeping the environment clean were the best measures to curb it, he added.

"Dengue fever is on the rise throughout the city though it is now the peak of the dry season," said Nguyen Trung Nghia, director of HCM City?s Preventive Health Centre.

Unseasonable rains and rising humidity had created optimum breeding conditions for mosquitoes, he said.

To tackle the menace, authorities have dispatched more health workers to high-risk areas, quickly responded to outbreaks and provided training to local teachers so that they can disseminate knowledge on preventive measures to their students.

The city?s Department of Health plans to launch a campaign this month to destroy mosquitoes and larvae in 11 districts and communes.

Bac Lieu Province has reported 239 cases so far this year, 100 fewer than the same period last year. But it plans to carry out a campaign April 20-25 to check the spread of the epidemic,
encouraging residents to participate in destroying mosquitoes and larvae, according to the provincial Preventive Health Centre.

The province reported 4,000 cases last year, including nine fatalities.


Hau Giang Province is also trying to increase awareness of dengue. All districts and communes in the province have reported hospitalisation of people for treatment. Soc Trang and Dong Thap provinces have also reported outbreaks of the disease.

Unseasonal rains increase dengue fever cases
Recent unseasonal rains have caused dengue fever outbreaks to rise sharply in Ho Chi Minh City.

Since February, the city?s Children?s Hospital No.1 received 30 to 35 patients with dengue fever per day. From the beginning of April the figure has risen to 80 patients per day.

The Tropical Diseases Hospital last week received more than 150 patients with dengue fever, an increase of 100 percent compared with the same period last year.

Dr. Le Bich Lien, dean of the Dengue Fever Department at the city children?s hospital No.1, said unseasonal rains have caused mosquitoes and larvae to develop earlier.

HCMC districts 8, Thu Duc, Tan Binh and Tan Phu are worst hit, with cases of dengue fever up by as much as 300 percent over the same period last year, says Nguyen Dac Tho, deputy director of the city?s Health Preventive Center.


Mr. Tho has instructed local health officials to take precautionary measures against the disease, as well as warn residents to remain vigilant and contain the epidemic.

Symptoms of dengue fever, a common mosquito-borne disease in developing countries, include flu-like fever, skin rashes and severe pain in the head and limbs.

Dengue fever is transmitted by daytime-biting mosquitoes. International health organizations recommend people use insect repellant and cover legs and arms.

Dengue fever ravishes southern Vietnam

More than 13,000 people in southern Vietnam have contracted dengue fever already this year, and 11 of them had died as of May 3, the director of the Pasteur Institute in Ho Chi Minh City said Friday.

The south, where the disease is far more prevalent, accounts for 84.4 percent of the current number of dengue fever cases nationwide, Dr. Tran Ngoc Huu told a press conference.

Dengue is no longer restricted to the rainy season and could strike at any time of the year, he said.

Unsurprisingly, it is among the top five infectious diseases with the highest numbers of cases and deaths in Vietnam.

The poor drainage in slum areas, a result of the country?s urbanization and industrialization, along with the warm climate create the ideal conditions for dengue fever to break out.

There is no commercial vaccine to protect against dengue yet, but several vaccines are at the experimental stage, Huu said.

The Pasteur Institute is working with Sanofi-Pasteur, the vaccines division of Sanofi-Aventis Group, to carry out clinical studies of Sanofi?s tetravalent dengue vaccine, which is also being trialed in Thailand, the Philippines and Singapore.

If the trials yield good results, a novel vaccine against dengue will be available in 2015 or 2016, said Wartel Nguyen N.T. Anh, SanofiPasteur?s regional medical director of clinical development.

The mosquito-borne disease, which is caused by any of four viruses, infects an estimated 230 million people annually and is a potential threat to almost half the world's population, according to Sanofi-Aventis.

HCMC enters dengue fever period

There has been an outbreak of dengue fever in Ho Chi Minh City despite few rains. Experts said that the disease has arrived earlier than expected.

Children between five to ten years old are the most vulnerable to the disease. At the city?s Tropical Hospital, 40 newborn babies are receiving treatment for dengue.

Many children have been hospitalized after early rains in April, said Dr. Tran Van Ngoc, head of the Pediatric Division.

The hospital is currently receiving 20-25 children per day.

At the city?s Pediatric Hospital No.2, doctors are treating 20 babies from districts 8, Binh Thanh and Thu Duc.

A total of 780 children have been taken to the hospital in the first four months of the year, 57 are serious cases.

The president of the Pasteur Institute, Tran Ngoc Huu, said that the city is entering a period of dengue fever, with an expected increase of patients compared to last year.

Twenty southern provinces have so far recorded 13,098 cases, a year-on-year increase of 28 percent, including 11 deaths. Most patients (around 6,000) come from Ho Chi Minh City, followed by Mekong Delta provinces of Ca Mau, Tien Giang and Soc Trang.

The city?s Preventive Health Department believes the outbreak of the disease has not occurred, as they usually disinfect and spray the environment and call for public awareness of environmental hygiene. However, Dr. Nguyen Thanh Hung, deputy director of Pediatric Hospital No.1 believes there has been an increase in patients since May.

Dengue fever is a leading cause of serious illness and death among children in some Asian countries.

Dengue fever sets in early this season

(23-05-2009)

HCM CITY ? It is not yet the peak season for dengue fever, but the number of people coming down with it has increased in southern and central regions, says a senior official of the Ministry of Health.

Nguyen Huy Nga, head of the ministry?s Preventive Medicine and Environment Department, said the rainy season has come early this year with increased rainfall, accounting for the rise in dengue fever cases.

In the cyclical rise and fall pattern that the disease follows, 2009 is a year of increase, and this is another factor, Nga said.

The HCM City Paediatrics Hospital No. 1 this week has received between 66 and 84 patients a day, double that of the previous month.

Dr Le Bich Lien, head of the hospital?s Dengue Fever Ward, said early onset of the rainy season has clearly seen the number of cases begin to go up earlier than in previous years.

Typically, the number of children contracting the disease increases in June, Lien said.

HCM City has led the country in dengue fever cases so far this year, with 3,600 cases and four fatalities, reported by the city?s Department of Health.

The number of dengue fever cases nationwide has risen to 16,600 in the first five months of the year, up 20 per cent against the same period last year, according to the Preventive Medicine and Environment Department.

Dengue fever cases are also surging in the Cuu Long (Mekong) Delta provinces of Kien Giang and Soc Trang; and the central province of Khanh Hoa.

Dengue fever has been included again this year in the national target programme to prevent and combat diseases, dangerous epidemics and HIV/AIDS, and a budget of VND70 billion (US$3.9 million) was set aside for prevention and control. Nga said about VND30 billion has already been disbursed to provinces and cities nationwide.

The remaining VND40 billion will be used for prevention measures including spraying chemicals to kill mosquitoes, increasing public awareness about prevention and control of the disease, and cleaning up the environment, he said.

He added that after two meetings on further preventive measures against dengue fever to be held next week, his department and localities nationwide would take drastic steps against the disease.

"Dengue fever could return strongly this year if drastic measures are not taken," Nga reiterated. ?VNS

The figures show a 46.7 percent increase year-on-year, and the number of people dying of the mosquito-borne illness is four higher than the same period last year.

According to the Hanoi Healthcare Preventative Center, the capital city is facing a potential outbreak of the disease with 80 cases reported so far this year.

Meanwhile, the Ministry of Health said the epidemic will continue in the south,
as rain combined with hot, humid weather creates conditions for mosquitoes to flourish.

As many as 920 people in the central province of Phu Yen have contracted dengue fever so far this year, a whopping 550 percent increase year-on-year, and two have died.


A meeting on tackling the epidemic in the province on Friday heard the fever had spread in the districts of Phu Hoa, Dong Hoa and Song Cau districts, as well as Tuy Hoa Town.

Head of the hospital?s Department of Infectious Diseases, Doan Van Hau, said it has only 25 beds, but there were more than 100 inpatients, 62 with dengue fever.

Since April, the department has received 429 dengue fever inpatients and mobilized all of the hospital?s personnel in providing treatment, but the resources were badly lacking, Hau added.


Phu Yen has had the central region?s highest incidence of dengue fever over the last five years, the meeting heard.

Dengue fever rampant in south central region

More than 1,000 cases of dengue fever were reported in Phu Yen province on June 24 and over 850 of the people who have contracted the disease are undergoing treatment at medical centres in central Khanh Hoa province.

The fever has also spread to 40 out of 63 communes and wards in the southern province of Ninh Thuan with nearly 300 cases. New outbreaks have been also reported Quy Nhon city, in Binh Dinh province.

In mid-June, the Nha Trang Pasteur Institute have supervised the epidemic in three provinces of Phu Yen, Khanh Hoa and Binh Dinh and instructed local centers to use chemicals to kill mosquito larva on a large scale.

It is worrying that July and August are the high seasons for dengue fever in the central region. So far, the Ministry of Health has not allocated any funds to local areas although some provinces have actively spent their budget on prevention activities.

At the same time, many children have been hospitalized due to the hot weather. Most of the children have either pneumonia, respiratory disorders, high fevers, diarrhoea or dengue fever.

In Quang Ngai province, nearly 130 children are undergoing treatment at the provincial hospital?s pediatrics department.

Bac Kan province?s pediatrics department has also admitted nearly 700 children since early May with 12-15 children being hospitalised daily. Most of them have caught the viral fever.

Pediatric doctors warn that parents should keep their children clean and drink plenty of boiled water to avoid food poisoning and dehydration.
