Yellow Fever
Geographical Spread
Ten years ago yellow fever was believed to be
restricted, as far as the South American continent
was concerned, to a district in the northeast
of Brazil, and to be rapidly disappearing as
a result of antimosquito services in a few of the
larger cities. It is now realized that yellow fever
is widely disseminated over the continent east
of the Andes and north of Paraguay, and the
hope that the disease might shortly be brought
under control or disappear has been deferred.
Ten years ago yellow fever was regarded as an
urban disease transmitted by Aedes aegypti, a
mosquito living and breeding almost entirely in
houses, whereas today it is known that yellow
fever is widespread in the interior and occurs as
a jungle disease hundreds of miles away from the
nearest Aedes aegypti habitat.
