According to the World Health Organization (WHO), on 13 August 2021, five Yellow fever cases tested positive by plaque reduction neutralization test (PRNT) at Intitut Pasteur in Dakar.
Based on differential tests returned on 6 September 2021, the results of three cases are consistent with a recent Yellow fever infection. Two other cases had cross-reactions with other flaviviruses, one of which was more consistent with dengue and one with a flavivirus infection (PRNT positive for Yellow fever, Zika, and dengue).
Yellow fever is an acute viral hemorrhagic fever.
Symptoms of yellow fever (fever, chills, headache, backache, and muscle aches) develop 3-6 days after infection. About 15% of people infected with yellow fever virus will develop severe illness that can lead to liver disease, bleeding, shock, organ failure, yellowing skin (jaundice), and sometimes death.
Diagnosis is based on symptoms, laboratory testing, and travel history. Yellow fever virus spreads through the bites of infected mosquitoes.
There are no medications to treat or cure yellow fever. Yellow fever vaccine is the best protection against this disease.
