Nigeria ends 21-day Ebola contact monitoring with no secondary transmission

What the report says

Nigerian health authorities have completed a 21-day monitoring period for 62 people identified as contacts of the country’s first Ebola case in more than a decade, with no secondary transmission detected, according to Al Jazeera’s report citing the Nigeria Centre for Disease Control and Prevention (NCDC). The agency said none of the contacts became ill, although 13 reported fever or other non-specific symptoms during the follow-up period and all tested negative.

The case was confirmed on October 20 in a Swiss woman who had travelled to Uganda and then returned to Nigeria. She and her husband were later evacuated to Switzerland, where she recovered and has since been discharged from hospital. Al Jazeera reported that the last monitored contact has now been discharged as well.

The NCDC said the completion of contact monitoring does not by itself mean the outbreak is over. Under World Health Organization guidance, countries must complete a 42-day countdown from the recovery or departure of the last confirmed patient before declaring an outbreak ended. That context matters because Ebola can spread through direct contact with bodily fluids or contaminated materials.

Al Jazeera also noted that seven Ebola alerts in five Nigerian states over the past three weeks were investigated and all tested negative. The broader outbreak in the region has been linked to the Bundibugyo strain, which has also been reported in several countries since an outbreak began in eastern Democratic Republic of the Congo earlier this year.
