Polio programme staff are conducting disease surveillance for COVID-19 as well as educating communities on the symptoms of the virus, how to prevent transmission, and how to report suspected cases. ©WHO/Somalia4 May 2020 – “The road to the mountain village was rough. It’s only 50 kilometres, but it took more than 3 hours,” says Dr Fatima Ismail, a disease surveillance officer working in Somaliland. “We were bouncing in the car.”
In early 2020, Dr Fatima’s team headed to a remote village near Djibouti to check on a small boy. The boy’s right arm and leg showed a kind of paralysis that sometimes indicates polio. “The village polio volunteer in this mountainous area, geographically inaccessible, found an acute flaccid paralysis (AFP) case,” Dr Fatima remembers.
When children show signs of this paralysis, it’s critical to get stool samples to a laboratory to determine whether they have polio. Polio teams ride camels in the desert or donkeys in the mountains when they have to. They brave bombs to get samples out of conflict zones to laboratories. In brutally hot climates, they plug mini-freezers into car dashboards to keep samples cool.
All over the world, polio surveillance systems that have been built up over decades track infection sources, evaluate symptoms and transport samples to the laboratory — despite distance, natural disasters, and sometimes war. Now, this network of disease surveillance — reaching into the most far-flung corners of the globe — is being tapped to address the COVID-19 pandemic.
“In Somalia, the polio programme pivoted its workforce of thousands of frontline staff to support the effort as the cases of COVID-19 spread. Rapid response teams — made up of disease surveillance officers, community health care workers and volunteers — were trained to educate people about the virus and to test suspected cases. By April 2020, the teams were deployed in the field,” said Dr Mamunur Malik, WHO Representative in Somalia.
