Travel Health Advice - Yellow fever

Yellow fever

What is it? Yellow Fever is a virus that causes an acute sickness in two distinct phases: first a fever, chills and headache, with muscular pain, nausea and/or vomiting. Then 15% of patients move to the second phase after a few days: more fever, jaundice, abdominal pain, vomiting and bleeding. Approximately 50% of these patients will die two weeks after onset of the stage two symptoms. How is it transmitted? By mosquito bite during the daylight hours, at altitudes below 2,500 metres. Where is it present? Predominantly tropical areas of Africa, Central and South America, parts of South-East Asia. Level of risk? High for travellers entering infected or high-risk areas without prior inoculation. What can I do to prevent getting it? Get a vaccination - this is mandatory for entry in many countries. Once there: avoid getting bitten by mosquitoes particularly during the day.
