A top health official in Kenya has died from coronavirus as the country deals with rising infections.

Kamau Mugenda was second in charge at the Kenya Medical Research Institute which oversees Covid-19 testing and vaccine trials programme.

More than 450 workers in the health ministry have been infected, and at least three frontline health workers have died, the BBC's Emmanuel Igunza reports from Nairobi.

Despite imposing strict measures to deal with the virus, cases have more than doubled over the past days.
Meanwhile, authorities in Kenya are investigating the disappearance of equipment and monies donated to help stop the spread of Covid-19, our correspondent adds.
