Circulating Vaccine-Derived Poliovirus in Laos

12 Oct 2015

WHO has been notified of a confirmed case of circulating vaccine-derived polio in Laos. The case is an 8-year-old boy who lived in the district of Bolikhan, in Bolikhamxay Province, central Laos. This area of Laos has a long history of poor polio vaccine coverage.

The boy developed paralysis on 7 September and sadly died on 11 September 2015. The last case of poliovirus in Laos was reported in 1993.

Comprehensive outbreak response activities are taking place in response to the outbreak.

Advice for Travellers

The vaccination recommendations for Laos have been amended, following the emergence of circulating vaccine-derived poliovirus in the country.

It should be confirmed that children have received their recommended doses of polio vaccine according to the UK childhood schedule. It is recommended that travellers have a poliomyelitis booster (or course) if not already protected. Travellers should also take precautions with food, water and personal hygiene.
