Recent Resurgence of Ebola Virus
October 25, 2021
The COVID-19 pandemic negatively impacted the epidemiological control of several infectious diseases worldwide. Specifically, Ebola virus disease has been sporadically resurging in Guinea and the Democratic Republic of the Congo (DRC) in 2021. A total of 16 confirmed and 7 probable cases were reported, of whom 12 people died in Guinea (1). Eleven confirmed cases and one probable case, six deaths and six recoveries were recorded in DRC (2). The coexistence of both outbreaks increased the burden on the country’s health system mainly because Ebola response programs were redirected to the COVID-19 national response (3, 4). The imposition of strict lockdowns threatened Ebola control activities, leading to inefficient Ebola surveillance and contact tracing. Importantly, genome sequencing analyses indicated that these Ebola outbreaks were sparked by the transmission of the virus from the survivors from previous epidemics, the 2013-2016 outbreak (Guinea) (5) and 2018–2020 outbreak (DRC) (6). These underline the risk for reemergence of the virus after interruption of active transmission.
