Yellow Fever
Yellow fever is a viral disease, which is spread by the bite of a mosquito. The geographical distribution of yellow fever is confined to Equatorial Africa and South America . Strangely yellow fever is unknown in Asia despite the presence of mosquitoes capable of spreading the virus.
Nevertheless in general, all travellers going to an endemic area require a yellow fever vaccination certificate and travellers going to some parts of Asia from an endemic region will also require a certificate.Please refr to list of countries .
Manifestation: The disease can have three different presentations:
Subclinical, without any symptoms. 2. Flu-like disease with:
Fever Muscle pain Head-ache Nausea Vomiting Recovery Severe fever with death in a few days with kidney failure, liver failure and haemorrhage. Diagnose and treatment : No curative treatment is available. Overall about 5% of patients die. Those who recover do so completely and are immune thereafter.
Vaccination : Vaccine against yellow fever is available and effective. This vaccine is recommended before travelling to several countries.
Prevent yellow fever by :
Vaccination Avoid mosquito bites by remaining in well screened areas Avoid mosquito bites by remaining in air-conditioned areas. Use mosquito repellents on skin and clothing Bring aerosol insecticides to use indoors Use bednets
