ongoing outbreak of yellow fever in Angola has global public
health officials closely monitoring the situation. The
European Centre for Disease Prevention and Control (ECDC)
updated its rapid risk assessment due to concerns of potential
international spread of the mosquito-borne disease.
says, "Currently, all regions in Angola should be
considered as areas at high risk of transmission of yellow
fever. The yellow fever outbreak in Uganda is unrelated to the
outbreak in Angola."
Clinic infectious diseases specialist Dr. Pritish Tosh says
yellow fever is a viral hemorrhagic fever that is spread by
infected mosquitos. Unlike other hemorrhagic diseases such as
Ebola and Marburg, yellow fever cannot be spread
person-to-person. Tosh says yellow fever can be prevented with
a highly effective vaccine; however, there are risks involved.
are some reactions from the live vaccine that are rarely, but
potentially life-threatening," he says. "Itís not
a vaccine we recommend for everyone across the board. You have
to weigh your risks and benefits. If you are going to an area
that is known to be endemic with yellow fever, and if you are
at high risk of being bitten by a mosquito, then the risk of
the vaccine is much lower than risk of infection. Yellow fever
infection is often very serious and potentially fatal."
adds, "It is important for those who are contemplating
going to one of these endemic areas of yellow fever to consult
with a travel medicine expert to discuss the risk of
fever is a viral infection spread by the Aedes aegypti
mosquito. The infection is most common in tropical and
subtropical areas of Africa and South America, affecting
travelers to the area and local residents.
