A strand of gonorrhoea resistant to most drugs used to treat the disease is now in Nairobi.
The finding, described by experts as “of concern”, means that many Kenyans are carrying an almost incurable infection that can cause significant health problems, including permanent damage to the reproductive system.
The drug-resistant gonorrhoea was isolated from a sample taken from one of 24 sick sex workers from Nairobi last year.
Amina Abdullahi, a researcher from the Kenya Medical Research Institute (Kemri) who made the discovery, said most of the sick women did not even have the clinical symptoms of gonorrhoea.
