Yellow fever is a serious viral infection , transmitted by mosquitoes in tropical regions.
In mild cases the symptoms are similar to influenza , but serious cases develop a high temperature and may have a series of after effects, such as internal bleeding, kidney failure and meningitis . Although a safe, efficient vaccine has been available for the last 60 years, epidemics still occur, constituting a health risk in tropical regions. The disease is covered by the International Quarantine Regulations, which are taken very seriously by authorities everywhere. Therefore the vaccine has to be administered by a specially authorised doctor. In the UK you can only obtain the yellow fever vaccination from a designated Yellow Fever Clinic.
