Dengue Virus And Transmission

Dengue fever outbreaks in Bangladesh have been prolonged due to climate change, increasing the risk of more infections during the monsoon season. The lack of a coordinated response has caused more deaths from this mosquito-transmitted disease, making it a major public health concern in the country.

Dengue fever is caused by the dengue virus, which is transmitted through the bite of infected Aedes mosquitoes, mainly the Aedes aegypti species. These mosquitoes become infected when they bite a person who already has the virus in their bloodstream, and then they can transmit the virus to other individuals they bite.

Here are some key points about the dengue virus and its transmission:

  • The dengue virus belongs to the Flaviviridae family and has four distinct serotypes, known as DENV-1, DENV-2, DENV-3, and DENV-4. Each serotype can cause dengue fever, and subsequent infections with different serotypes can lead to more severe forms of the disease.
  • Mosquitoes become infected with the dengue virus when they feed on the blood of a person with dengue fever during the first few days of the illness.
  • Once infected, the mosquito remains a carrier of the virus for their entire life, which can be up to a month.
  • Female Aedes mosquitoes, which are responsible for dengue transmission, lay their eggs in containers or areas with stagnant water, such as flowerpots, discarded tires, and open water tanks.
  • The eggs can survive in dry conditions for several months, waiting for favorable conditions to hatch, such as rainfall or the presence of water.
  • The mosquito larvae hatch from the eggs and develop into pupae and then into adults, ready to bite and transmit the virus to humans.
  • The Aedes mosquitoes are primarily active during the day, with their peak biting periods occurring in the early morning and late afternoon.
  • Dengue virus cannot be directly transmitted from person to person. Instead, it requires the intermediate vector of the Aedes mosquito for transmission.
  • It’s important to note that while dengue is primarily transmitted by mosquitoes, there have been rare cases of transmission through blood transfusions, organ transplants, and vertical transmission from a pregnant woman to her fetus.

Understanding the virus and its mode of transmission is crucial for effective preventive measures and control strategies. By focusing on mosquito control and reducing breeding sites, we can help minimize the spread of dengue fever and protect public health.
