Surveillance: The Key to Polio Eradication

Dedicated vaccination campaigns have interrupted the spread of polio in Africa, but there is still much work ahead to eradicate the disease.

The director of the Polio Global Eradication Initiative, Hamid Jafari, notes that, “In the past we have had year-long periods when we thought the poliovirus had gone … only to find out that we were simply missing transmission because our surveillance systems were not strong enough to spot cases.”

The next step, according to WHO, will be to continue monitoring the region for additional wild polio cases. If none appear in the next 2 years, Africa will be certified polio-free.
