2019-11-20 | Pakistan | Infectious | Acute Flaccid Paralysis | Through national disease surveillance, an outbreak of cVDPV2 has been confirmed in Pakistan in 2019. Between 7 July and 5 November, seven children have been paralysed from cVDPV2 in northern Pakistan – four in Diamer district, Gilgit-Baltistan province, one in MCI Islamabad, one in Torghar and one in Kohistan, Khyber Pakhtunkhwa province. The cases have a date of onset of paralyses between 7 July and 6 October 2019. Moreover, the virus was also isolated in stool samples from three contacts of patients experiencing acute flaccid paralysis (two contacts from Diamir and one contact from Torghar), as well as in 16 healthy children from Diamer, Kohistan and Rawalpindi districts and in seven environmental samples from Rawalpindi and Lahore districts in Punjab province, Diamer and Gilgit districts in Gilgit-Baltistan province and Karachi district in Sindh province.
All environmental samples were collected between 21 August to 7 October 2019. The genetic sequencing confirms that the isolated VDPV2 from the environmental surveillance samples collected at the Safdarabad site in Rawalpindi district in August is linked to a virus isolated from Diamer environmental surveillance samples collected in August and September, which indicates a circulating VDPV2 outbreak. Pakistan is classified as endemic for wild poliovirus and as of 13 November, there have been 82 cases of wild poliovirus type 1 (WPV1) reported in the country in 2019 compared to 12 cases in 2018. The last VDPV2 case in Pakistan was reported from Quetta city, Balochistan province in December 2016 and was classified as a cVDPV2. WHO is currently assessing the risk of spread of cVDPV2 within the country as high due to the high population movement, strong connectivity across the country, and low population immunity against type 2 poliovirus WHO does not recommend any restriction on travel and/or trade to Pakistan based on the information available for the current polio outbreak.

The patient was in a critical condition in an isolated ward. After the treatment, he had recovered and been discharged from the local hospital on 14 November. He went back to Australia on 16 November. Epidemiological investigations and contact tracing are ongoing. Close contacts on the cruise ship were identified and were given prophylaxis regardless of vaccination history. The cruise ship on which the patient was travelling has stopped at five ports in Japan and will stop at five additional ports in Japan and another port in the Republic of Korea.
