Nigeria is the fifth country, and the clock started on 11 October

Nigeria has confirmed its first case of Ebola disease caused by the Bundibugyo virus, the World Health Organization said on Wednesday¹. The patient is a woman who had recently travelled from Uganda. She developed symptoms on 7 October, four days after arriving, sought care at a private health facility in Abuja on 11 October, and was confirmed by laboratory testing on 20 October¹. She is in isolation and receiving care¹.

The nine days. Desk arithmetic: 11 October to 20 October is nine days between her first visit to a clinic and a confirmed result. That gap is where contacts accumulate. Nigerian authorities have so far identified 44 contacts under monitoring, and infection control is being strengthened at the clinic where she was seen¹. The Nigeria Centre for Disease Control and Prevention has activated its incident management system, and WHO is supplying protective equipment and help with tracing¹.

The wider picture. Nigeria is the fifth country to detect the disease since the outbreak in the Democratic Republic of the Congo was declared in mid-May¹. The ECDC counts 9,552 confirmed cases and 4,602 deaths in the DRC, from data to 18 October². There is no licensed vaccine or specific treatment for this species¹. WHO has not recommended any restrictions on travel or trade, and asks countries in the region to keep a high level of readiness¹.

For readers in Europe. The ECDC’s modelling still puts the risk of importation into the EU/EEA at very low, even in a pessimistic scenario, though sporadic imported cases cannot be excluded². Nothing here is a reason to change your plans.

The constructive reading: a new country is bad news, but a case found, isolated and surrounded by a list of 44 names is the system catching up. Watch the list, not the map.
