The World Health Organization says that seven African countries have cumulatively reported about 1,400 monkeypox cases this year up to mid-May. These, the BBC reports, were recorded in Cameroon, the Central African Republic, the DRC, Liberia, Nigeria, Congo-Brazzaville, and Sierra Leone. The health organization says though that the number of cases this year is slightly fewer than half of the cases reported last year. The WHO notes that while the virus has not spread to new African countries where it is not common, it has been expanding its geographic reach in recent years.
