ISLAMABAD (Reuters) - A brain-eating amoeba has killed at least 10 people in Pakistan's most populous city since May, a World Health Organization official said on Tuesday.
Naegleria fowleri has a fatality rate of more than 98 percent. It is transmitted when contaminated water enters the body through the nose and cannot be passed person-to-person.
The 10 confirmed cases have all occurred in the southern port city of Karachi, said Dr Musa Khan, head of the WHO's Disease Early Warning System in Pakistan.
It is unclear if all cases have been reported as residents may not be familiar with the disease and Pakistan's hospitals are severely overstretched.
The amoeba travels from the nasal membranes to the brain. Symptoms are initially very mild, including a headache, stiff neck, fever and stomach pain. Death usually occurs five to seven days after infection.
