Yellow fever is a serious disease, which occurs in parts of Africa and some South American coutries. It is transmitted by the female Aedes aegypti mosquitoes and can carry high mortality.
Vaccination may be required before visiting some parts of Africa and South America considered to be endemic zones. This is to stop the disease spreading into other countries and to protect the travellers themselves.
The Yellow Fever Vaccination is not available through many family doctors and travellers usually must visit approved Yellow Fever Vaccination centres to have the Yellow Fever Vaccination
Yellow Fever is caused by a virus and spread to humans by the bite of an infected mosquito. The virus causes sudden onset of fever, four days after the bite. Most cases are mild, last less than a week, and the person makes a full recovery. Sometimes it is more serious. The liver may be damaged leading to jaundice - a yellowish tinge to the skin. Hence the name 'yellow' fever. It may cause joint pain and vomiting.
Eventually the clotting system fails and bleeding occurs from the nose, gums, stomach and skin.(Hemorrhagic Fever) Up to ten percent of sufferers will die.
In indigenous populations in endemic areas the fatality is about 5%. For travellers to rural parts of yellow-fever risk areas, the risk of contracting infection is high and the case fatality rate can approach 50%, even if the country has not officially reported the disease and does not require evidence of immunisation on entry.
The incubation period is generally 3 to 6 days but may be longer. Death usually occurs 7 to 10 days after the onset of the illness.
Yellow fever is difficult to recognize, especially during the early stages, and can be easily confused with diseases including malaria, typhoid, rickettsial diseases, hemorrhagic viral fevers, dengue fever, and viral hepatitis. Diagnosis of yellow fever requires a blood test and trained staff using specialized equipment and materials.There is no specific treatment for yellow fever.
Current estimates indicate 200,000 yellow fever cases with 30,000 deaths each year, and almost all in sub-Saharan Africa where over 460 million people in 33 countries are at risk of infection.
