What is it: Rift Valley fever (RVF) is an acute,
fever-causing viral disease that affects domestic animals (such as
cattle, buffalo, sheep, goats, and camels) and humans.  RVF is
most commonly associated with mosquito-borne epidemics during years
of heavy rainfall.

Where could I get it: RVF is generally found in regions of
eastern and southern Africa where sheep and cattle are
raised.  However, RVF virus also exists in most countries of
sub-Saharan Africa and Madagascar.

What happens if I get it: people with RVF typically have
either no symptoms or a mild illness associated with fever and
liver abnormalities.  In some more extreme cases, it can lead
to hemorrhagic fever (which can lead to shock or haemorrhage),
encephalitis (inflammation of the brain, which can lead to
headaches, coma, or seizures), and eye disease.

What do I do if I get it: usually patients recover within
two days to one week after onset of illness.  About 1% of
humans that become infected with RVF die of the disease. 
There is no specific treatment – just rest and taking plenty of
fluids.

How can I prevent catching Rift Valley Fever: avoid bites of
mosquitoes and other blood-sucking insects, so use of mosquito
repellents and bed nets.  Also you should avoid exposure to
blood or tissues of animals that may potentially be infected.
