Bahsmiris received
his mosquito net which offers protection against mosquitos,
flies, and other insects, and thus against the diseases they
may carry.
Examples include malaria, dengue
fever, yellow fever, and various forms of encephalitis, including
the West Nile virus.
To be effective the mesh of a
mosquito net must be fine enough to exclude such insects without
impeding visibility or the flow of air unacceptably. It is
possible to increase the effectiveness of a mosquito net greatly
by treating it with an appropriate insecticide or mosquito
repellant.
