Meningococcal meningitis is a bacterial infection affecting the brain usually spread by respiratory droplets (coughing/sneezing). Highest infection rates usually occur during the dry season in the ‘meningitis belt’ of sub-Saharan Africa. The risk is highest for long-stay travellers and those mixing closely with the local population. There are a number of different strains of meningococcal meningitis and the vaccine used for traveller purposes contains 4 of these (A, C, W135 and Y).


23 cases of acute flaccid paralysis have been reported in Deir al Zour Governate, May 17. It is suspected that these cases have been caused by circulation of vaccine derived poliovirus among the inadequately vaccinated population.

Polio is a viral infection which can sometimes cause long term paralysis. It is usually spread by contaminated food and water in areas with poor sanitation. Vaccination is part of the standard UK immunisation schedule and boosters are given in combination with tetanus and diphtheria.
