Polio reappears in Nigeria; 2 reported paralysed
According to reports, polio has reappeared in Nigeria, with two children having been paralysed by wild-type polio virus. Findings suggest that the virus may have been circulating undetected for years in the country, with non-existent to poor vaccination in militant-controlled areas. Nigeria, which was celebrating 2 years without a wild polio case, launched a mass vaccination campaign in response.
