After the deaths of 14 children in the last few months, health experts are now warning that Nairobi and several other districts could be on the verge of a measles outbreak. After the upsurge in cases and deaths caused by the highly infectious disease, the Government issued a red alert after three children died in Nairobi's Kayole estate last week. The children aged six, five and eight months died one after the other over a period of 10 days.
