The dengue tally in Delhi reached a five-year high this year after a total of 187 cases was reported, which is highest for the period since 2018.
About Dengue:
It is caused by the dengue virus (DENV)
It is transmitted to humans through the bites of infected female mosquitoes, primarily the Aedes aegypti mosquito.
The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
It is more common in tropical and subtropical climates.
Symptoms: The most common symptoms are high fever, headache, body aches, nausea and rash.
Most will also get better in 1–2 weeks but in severe cases it can be fatal.
Treatment:
There is no specific treatment for dengue.
Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%.
The dengue vaccine CYD-TDV or Dengvaxia was approved by the US Food & Drug Administration in 2019, the first dengue vaccine to get the regulatory nod in the US.
