Avoiding Yellow Fever in Brazil
The yellow fever virus is transmitted by female mosquitoes and is endemic in tropical areas. In Brazil, the current outbreak relates to sylvatic (jungle) yellow fever. Local correspondents in Brazil, Proinde P&I, have issued a circular detailing the nature of the virus and how to avoid infection.
Typical symptoms appear after three to six days and include fever, muscle pain, intense headaches, shivers, loss of appetite and nausea. It is reported that about 15% of patients progress into a more toxic phase of the infection, which has symptoms such as high fever, jaundice and abdominal pain with vomiting. Half of the infected people who enter the more severe form of the infection die within a couple of weeks.
