2019-12-24 Malaysia Infectious Polio-myelitis, Acute Paralytic, Vaccine Associated On 6 December 2019, the National IHR Focal Point of Malaysia informed WHO of the detection of cVDPV1 in Sabah, Malaysia, following confirmation by the WHO  Regional Reference Laboratory (RRL) at the Victorian Infectious Diseases Reference Laboratory (VIDRL) in Australia. The case is a 3-month-old male Malaysian citizen, from Damat Village in Tuaran District, Sabah State, Malaysia, who developed fever on 26 October 2019, followed by seizures on the 30th October 2019 and a rectal swab sample was taken from the baby on that day. The baby was diagnosed as having Acute Flaccid Paralysis (AFP) on 8 November 2019.  

The virus was found to be genetically linked to the strain that was recently isolated from an AFP case detected in Basilan, Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), Philippines (confirmed on 22 November). This VDPV type 1 is therefore classified as circulating VDPV type 1(cVDPV1), between Basilan, BARMM, Phillipine and Sabah, Malaysia.

Initial investigations, showed no apparent travel history to the Philippines, but had given history of receiving frequent visitors from the Phillipines to the family house. The possible source of infection is still under investigation.

WHO currently assesses the risk of the spread of cVDPV1 within the country and regionally as high due to the population movement both within the country and within the region

WHO does not recommend any restriction on travel and/or trade based on the information available for the current polio event.
