WHO urges swift action as dengue cases surge in Bangladesh
A significant surge in dengue fever cases has gripped Bangladesh, the UN World Health Organization (WHO) reports on Friday, calling for efforts to control the mosquito vector population and minimize individual exposure such as using mosquito repellents and wearing long-sleeved clothes, reports BSS.
The outbreak, which escalated rapidly since late June, has seen a total of 69,483 confirmed cases and 327 related deaths between 1 January and 7 August, with a case fatality rate of 0.47 per cent, according to the UN health agency. The cases were reported from all 64 districts in the country, the agency said a statement.
In July alone, 43,854 cases and 204 deaths were reported, accounting for 63 per cent of the total cases and 62 per cent of the deaths. The sharp increase in numbers is unprecedented compared to the past five years, emphasizing the gravity of the ongoing outbreak.
"The higher incidence of dengue is taking place in the context of an unusual episodic amount of rainfall, combined with high temperatures and high humidity, which have resulted in an increased mosquito population throughout Bangladesh,"
Most people with dengue have mild or no symptoms and get better within two weeks. Rarely, dengue can be severe and lead to death. If symptoms occur, they usually begin four to 10 days after infection and last for two to seven days.
Symptoms may include high fever (40oC, or 104oF), severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands, and rash.
Severe dengue symptoms often come after the fever has gone away and may include severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums or nose, fatigue, restlessness, blood in vomit or stool, being very thirsty, pale and cold skin, and feeling weak.
People with these severe symptoms should seek medical care right away.
Dengue, a viral infection that transmits through mosquito bites, has long plagued tropical and sub-tropical regions. Aedes aegypti and Aedes albopictus mosquitoes serve as the primary vectors for the disease. An infected mosquito can transmit the virus for the rest of its life.
While there is currently no specific treatment for dengue, early detection and appropriate healthcare for case management can significantly reduce mortality.
According to WHO, the focus is on treating pain symptoms. Acetaminophen (paracetamol) is often used to control pain. Non-steroidal anti-inflammatory drugs like ibuprofen and aspirin should be avoided as they can increase the risk of bleeding.
Bangladesh's health authorities have established a dedicated dengue control room to collect data and coordinate at the national level, with additional control rooms in all districts and medical college hospitals.
Six hospitals assigned for the management of Covid-19 patients in the capital, Dhaka, have been repurposed for dengue case management, and dedicated dengue wards and dengue corners have been established in medical college hospitals.
