This week, Health Surveillance of Camaquã in the state of Rio Grande do Sul, Brazil issued an alert for yellow fever in the interior of the municipality. Four dead howler monkeys were found, one of which underwent testing to identify the presence of the disease, transmitted by the Aedes Aegypti mosquito.
According to the coordinator of Surveillance, Fabiano Martins, two dead howler monkeys were found in Santa Auta, one in Vila Aurora and the other in Banhado no Colégio. The latter had the most recent death and, therefore, it was possible to collect material for analysis.
Last week, the Municipal and State Health Surveillance teams carried out orientation and awareness visits about Yellow Fever in the interior of the Municipality.
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.
