facts for dengue

Fast facts about the mosquito
  • Only the female aedes mosquito bites as it needs the protein in blood to develop its eggs.
  • The mosquito becomes infective approximately 7 days after it has bitten a person carrying the virus. This is the extrinsic incubation period, during which time the virus replicates in the mosquito and reaches the salivary glands.
  • Peak biting is at dawn and dusk.
  • The average lifespan of an Aedes mosquito in Nature is 2 weeks
  • The mosquito can lay eggs about 3 times in its lifetime, and about 100 eggs are produced each time.
  • The eggs can lie dormant in dry conditions for up to about 9 months, after which they can hatch if exposed to favourable conditions, i.e. water and food
