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.
