Virus hunters: The scientists tracking deadly diseases in tough conditions

Amid threats from mpox and new unknown viruses, how do epidemiologists track pathogens before a health crisis begins?
It was September 2017 at a teaching hospital in Nigeria’s southern state of Bayelsa. An 11-year-old boy came into the clinic with a fever, rash and lesions on his body.
Infectious disease scientist and Chief Medical Director Dimie Ogoina examined him. At first, doctors thought it could be chickenpox, but after hearing the boy had previously had the illness, they suspected it must be something more serious.
Upon further examination, Ogoina concluded that it was likely monkeypox, a highly infectious disease that causes a skin rash, mucosal lesions and other symptoms the boy was experiencing.
It was a stunning finding. The last case of monkeypox – now called mpox – detected in Nigeria was nearly 40 years earlier. And even then, there were only two cases ever recorded. The country was not prepared for it.
At that point, Ogoina couldn’t be certain of the diagnosis, though. He first had to notify the Nigeria Centre for Disease Control and Prevention, which needed to take a sample and then send it to the Institut Pasteur in Dakar, Senegal, for testing. The process took days, but when the results came in, it was as Ogoina had suspected.
