Dengue fever is mainly spread by the bite of infected Aedes mosquitoes, which includes A. aegypti and A. albopictus mosquitoes. A mosquito becomes infected when it bites a person who has dengue in his or her blood.

Does every Aedes mosquito carry dengue?

Foremost, you need to bust the dengue myth that every mosquito bite will cause dengue. Only the female Aedes aegypti mosquitoes can spread the dengue virus and in fact, these mosquitoes can transfer the infection only when they themselves are infected. So, no need to panic after each mosquito bite.

Can normal mosquito spread dengue?

Dengue virus can be contracted from the bite of an infected Aedes mosquito. Mosquitoes become infected when they bite infected humans, and can later transmit the infection to other people. Dengue cannot be transmitted from person to person without a mosquito as the intermediate vector.

What type of mosquito causes dengue?

How do I know if I have an Aedes mosquito bite?

They usually bite you on the ankles and elbows. The only way to differentiate between a dengue mosquito bite and a normal mosquito bite is that that a dengue mosquito bite is much redder and itchy compared to a normal mosquito bite.

How much platelet count is normal in dengue?

A typical person has a platelet count of between 150,000 and 250,000 per microlitre of blood. About 80 to 90 per cent of patients with dengue will have levels below 100,000, while 10 to 20 per cent of patients will see critically low levels of 20,000 or less.

Which disease is spread by mosquitoes?

How fast does platelet count drop in dengue?

The platelet counts drop below normal level (150,000–450,000 platelets/μL) and may reach as low as <40000 platelets/μL during day 3–7 of fever in many patients⁶.

When will platelets start increasing in dengue?

Higher platelet count at presentation was associated with early recovery time (p<0.033). Of 108(78%) patients who presented with platelet count of 20,000-<50,000/mm3, platelet count of 36(33.33%) rose to >50,000/mm3 within 2 days, and 62(57.4%) rose to >50,000 in 3-5 days.

Why platelets are low in dengue?

When an infected mosquito bites a human, the dengue virus enters the bloodstream, it binds to platelets and replicates leading to multiplication of infectious virus. The infected platelet cells tend to destroy normal platelets which is one of the major causes for the drop in the platelet count in dengue fever.

Which mosquito causes malaria and dengue?
