On 23 April WHO reported an outbreak of Ebola in the Democratic Republic of Congo (DRC). A patient aged 31 began experiencing symptoms on 5 April. He was sick for over a week before going to a local health facility. On 21 April he was admitted to an Ebola treatment centre but died that day. Recognising the symptoms, health workers submitted samples to test for Ebola. Now there are investigations to determine the source of the outbreak. The disease has had a two-week head start and medics are playing catch-up. The positive news is that the health authorities have more experience than anyone else in the world at controlling Ebola outbreaks quickly. By 27 April everyone had been inoculated in the province’s capital city, and over 230 Ebola contacts had been identified and monitored. Three vaccination teams will soon reach those at highest risk.
