What is the route of transmission for dengue fever?
Through Mosquito Bites Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus).
How does dengue hemorrhagic fever happen?
Dengue hemorrhagic fever can occur when someone is bitten by an infected mosquito or exposed to infected blood. Mosquitoes are the most common cause. There are four different types of the dengue virus. Once you contract one of the viruses, you develop immunity to that virus for the rest of your life.
What vector causes dengue hemorrhagic fever?
The dengue virus is carried and spread by mosquitoes in the genus Aedes, which includes a number of mosquito species. Of these species, the primary vector of the dengue virus is the species Aedes aegypti. It is the principal dengue vector responsible for dengue transmission and dengue epidemics.
What is hemorrhagic dengue?
Mild dengue fever causes a high fever and flu-like symptoms. The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
What is a vector transmission?
Vector transmission utilizes insects to transport the pathogen. Insects such as fleas, ticks, and mosquitos are unharmed by the pathogens they potentially carry but can transmit the bacteria or virus when they bite a host.
What is difference between dengue fever and hemorrhagic fever?
Despite the name, the critical feature that distinguishes DHF from dengue fever is not hemorrhaging, but rather plasma leakage resulting from increased vascular permeability. EVALUATE the patient’s heart rate, capillary refill, skin color and temperature, peripheral pulse volume, pulse pressure, and blood pressure.
What is the difference between dengue hemorrhagic fever and dengue fever?
DHF is a more severe form of dengue. Initial symptoms are the same as dengue but are followed by bleeding problems such as easy bruising, skin hemorrhages, bleeding from the nose or gums, and possible bleeding of the internal organs. DHF is very rare.
