About half of the world’s population is at risk of
contracting dengue, according to the World
Health Organization. The mosquito is found
in tropical and subtropical climates around
the world; however, dengue does not
naturally occur in these creatures: the
mosquitoes get dengue from us. The mechanism of dengue infection is simple. Female
mosquitoes bite humans because they need the protein
found in our blood to produce eggs. (Male mosquitoes do
not bite.) If the mosquito bites someone with dengue – and
then, after the virus’s roughly eight
to 12 day
replication
period, bites someone else – it passes dengue into its next
victim’s bloodstream.There is no vaccine against dengue, but infecting
mosquitoes with a natural bacterium called Wolbachia
blocks the insects’ ability to pass the disease to humans.
The microbe spreads among both male and female
mosquitoes: infected females lay eggs that harbor the
bacterium, and when Wolbachiafree
females mate with
infected males, their eggs simply do not hatch. Researchers
are now releasing Wolbachia-infected
females into the wild
in Australia, Vietnam, Indonesia and Brazil.
