In addition, Dive announced Friday, the confirmed death of a monkey due to the yellow fever virus in Pedras Grandes, in the South. To date, 137 were confirmed with yellow fever.

All residents of Santa Catarina older than nine months must be immunized. The coverage recommended by the Ministry of Health is at least 95% of this target audience to be immunized. Until the month of October 2021, vaccination coverage in Santa Catarina was 79.57%.

Yellow fever is an acute viral hemorrhagic fever that spreads through the bites of infected mosquitoes.

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.

There are no medications to treat or cure yellow fever. Yellow fever vaccine is the best protection against this disease.
