Dengue cases rise about a quarter of a century from their peak

The situation is becoming more alarming as the virus is being found in more areas and the country’s healthcare sector has already been strained by the prolonged fight against Covid-19.

Addressing a Friday conference at HCMC on dengue prevention and control, Dr. Long Chan Quang of the Ho Chi Minh City Institute Pasteur said the number was only lower than what was recorded in Vietnam in 1998.

Vietnam has recorded more than 211,000 cases of dengue fever so far this year and 87 patients have died, 4.3 times the number of patients and 68 more deaths compared to the same period last year.

For this year, he said, climate change and rapid urbanization are likely to have affected the habitat of the Aedes mosquito, the main carrier of the dengue virus, causing the virus to appear in more places than before.

He said the Central Highlands province of Lam Dong, for example, had not recorded any cases of dengue, but this year was different.

Another reason for the high number of dengue deaths this year is the shortage of medical personnel.

In HCMC alone, after the latest Covid-19 outbreak that lasted from June to October last year, 400 health care workers at the departmental/municipal medical centers have resigned. These workers are at the forefront of the fight against infectious diseases.

In most cases, they reported overload and low income as reasons for smoking cessation.

Meanwhile, many localities do not have sufficient funds to monitor and prevent the spread of disease. Some do not even contain chemicals to spray and kill mosquitoes in breeding areas, Kwang said.

Do Thi Hung Hin, WHO representative in Vietnam, said that after nearly three years of fighting Covid-19, “Vietnam is exhausted in terms of budget and human resources.

“There is now a serious imbalance between these resources and actual patient demand,” she said.

Nguyen Thanh Hung, director of HCMC’s No. 1 Children’s Hospital, said the condition of 10-30% of dengue patients is likely to become severe if it is not caught early. Once cases become severe, patients develop rapidly critical symptoms, especially children under one year of age, obese patients, pregnant women and those with other chronic diseases.

In most cases, dengue patients and their families ignore warning signs, inadvertently allowing the disease to become dangerous, said Pham Van Quang, head of the intensive care unit at Ho Chi Minh City No. 1 Children’s Hospital.

When exposed to high body temperatures, which is the most common early symptom of dengue fever, most patients choose treatment at home, Kwang said. In the Express.

After the high fever subsides, people assume they have already recovered.

However, in cases of dengue, the period after a high temperature is the most dangerous, and patients should be carefully monitored every step of the way, he said.

Vietnam is trying to find an effective way to treat dengue fever, one of the biggest killers among the 28 common infectious diseases it faces. The only universally available vaccine is not recommended for people who have never had dengue fever.

The World Health Organization (WHO) said in January that the incidence of dengue has grown significantly worldwide in recent decades and that the vast majority of cases are asymptomatic or moderate and are self-managed, so the actual numbers of dengue cases are lower than reported.

The number of dengue cases reported to the World Health Organization has increased eightfold over the past two decades, from 505,430 cases in 2000 to more than 2.4 million in 2010 and 5.2 million in 2019. Reported deaths increased between 2000 and 2015 from 960 to 4,032 cases, affecting most of them from younger age groups, she said.
