"This new case of polio was reported in Bihsud district of the province. The child who was infected by the disease is 48 months old. Nangarhar and all eastern zones of the country are in danger of polio," read a statement issued by the Afghanistan government as quoted by Tolo News.

An official of UNICEF, Kama Shah Sayed, said that that the children who are deprived of the vaccine are most likely to be affected by the polio.

"However, there have been many campaigns for polio, but still polio cases happen, the reason is that the children who are deprived of vaccine, are being affected," he  told Tolo News.

Meanwhile, some residents of Nangarhar urged officials to launch further vaccination campaigns.

"The medical teams should be increased. The common people should be advised about it," said Mohibullah, a resident of Nangarhar.
