Nigeria ends 21-day Ebola contact monitoring with no secondary transmission
Thirteen symptomatic contacts tested negative as authorities said WHO rules require 42 days before an official end-of-outbreak declaration.
On Friday, the Nigeria Centre for Disease Control and Prevention announced that the 21-day monitoring period for 62 contacts linked to Nigeria's imported Ebola case has concluded with none falling ill.
Nigeria confirmed its first Ebola case in over a decade on October 20 in a Swiss woman who had traveled to Uganda and returned to Nigeria; she and her husband were evacuated to Switzerland.
Thirteen contacts reported fever or other non-specific symptoms during monitoring, but all 13 tested negative for the virus. The NCDC investigated seven Ebola alerts across five Nigerian states, finding all seven tested negative.
The NCDC cautioned that completing contact monitoring does not mean the outbreak is over, emphasizing that the disease threat remains under assessment.
According to WHO protocols, a country must complete a full 42-day countdown from the recovery or departure of the last confirmed patient before an official end-of-outbreak declaration can be made.
