Type-1 wild poliovirus has crippled a 4-year child in Afghanistan,
marking it the 1st case of polio in Afghanistan and the 2nd case
globally this year [2023], stated Pakistan’s National Polio Laboratory
at the National Institutes of Health (NIH) Islamabad. The NIH
Islamabad official maintained that the polio case was reported on [16
Apr 2023] from Nangarhar University Hospital located in Jalalabad city
and investigated by collecting 2 stool samples on [17 and 18 Apr
2023].
“This is the 1st WPV1 case reported in Afghanistan in 2023. Last polio
case in Afghanistan was reported from Dara-e Pech District of Kunar on
[29 Aug 2022],” the official said, adding that wild poliovirus type-1
was circulating in the environment in Nangarhar province since last
many months, which also travelled to various areas of Khyber
Pakhtunkhwa, Pakistan.
The official maintained that the recent case was reported from Sepiaw
village of Batikot district. The village is in SIAs cluster 18 and is
around 3 km [1.9 mi] away from the nearest health facility named
Batikot CHC.
“The village is well covered through EPI routine fix sessions. The
child had received 3 doses in routine immunization and more than 7
doses in SIAs. However, the hygienic conditions are poor in the
village,” he added.
Citing health authorities in Afghanistan, the official said health
authorities conducted active case search in the nearby villages but
did not find any new or unreported AFP cases. The district of Batikot
reported 5 WPV1 positive environmental samples in 2022 and 7 samples
in 2023. The last WPV1 positive environmental sample was collected on
[25 Apr 2023].
