Body ache

Yellow fever symptoms often occur from 3 to 6 days after being bitten by an infected mosquito. The earliest signs of this disease are sudden, severe body aches. All of these symptoms subside after a few days. Some experience a high fever, nausea, and vomiting a few hours or days after the first symptoms go away, while others recover. Because the liver is diseased, the skin turns yellow (jaundice).

Many countries require vaccination only for travelers coming into their country from areas where yellow fever occurs. People should get vaccinated if they are traveling to regions where yellow fever is widespread. There is a vaccination available for use by residents of countries with endemic diseases and for visitors to regions where yellow fever is common, but it's also important to avoid mosquito bites. Plan to get the vaccine at least 10 days before your travel since proof of vaccination is not valid until 10 days after getting the vaccine, the time needed to develop immunity to yellow fever virus.
