A seasonal rise in the number of cases of aseptic meningitis has been reported from Astana in Kazakhstan. The Health Department say that this is not an outbreak as a similar number was recorded in the same time period of 2013.
As of 25 July 2014, 160 suspected meningitis cases have been admitted to hospital with symptoms. Of those, 139 were clinically classed as serious meningitis and 50 have been laboratory-confirmed as aseptic meningitis. The majority (95%) of cases are in children under the age of 14 years.
The most common cause of aseptic meningitis is a viral infection and enteroviruses are usually the cause of viral meningitis; particularly in children during the summer months. There is no vaccine against viral meningitis. A high standard of food, water and personal hygiene should be maintained to help lower the risk of enterovirus infections.
Aseptic meningitis may also be caused by arboviruses, HIV, herpes simplex viruses 1 and 2, some bacteris, fungi and parasites.
