Dengue infection

I would like to know: (A) what are your odds of getting sick with Dengue if you get bitten by an infected mosquito and (B) how long from the time of infection until symptoms surface (assuming you fall sick).

Hi @wolfie94 ,

These are very good questions and pertinent at this point in time.

An aedes mosquito becomes infected after it takes a blood meal from a dengue-infected person. It becomes infective after an extrinsic incubation period of 8 to 12 days. The mosquito then remains infective for the rest of its lifespan. 

When a person is bitten by an infective mosquito, they may develop symptoms after an intrinsic incubation period of 4 to 7 days (ranges from 3 to 14 days). This is what we usually call as incubation period. 

Notably, up to 75% of dengue infections are asymptomatic.

As always prevention is better than cure. Please Follow the 5 step mossie wipeout and let’s all do our part to reduce the transmission rate.

Does this mean I can be infected with the dengue virus but be completely fine and functional? (i.e no fever or only having mild symptoms etc.)
