Angola: updated recommendations for polio vaccination

Circulating vaccine-derived poliovirus (cVDPV) is confirmed in Cambulo province, Lunda Notre district, Angola Angola: updated recommendations for polio vaccination

As of 12 June 2019, the Global Polio Eradication Initiative (GPEI) reported two cases of circulating vaccine-derived polio virus type 2 (cVDPV2) in Cambulo district of Lunda Notre province, Angola [1]. The first case presented with onset of paralysis on 5 Apr 2019; cVDPV2 was also confirmed by laboratory testing of a close contact of the first case. Cambulo district borders areas of the Democratic Republic of Congo (DRC) where monovalent OPV type 2 (mOPV2) vaccination rounds have been conducted in response to ongoing cVDPV2 outbreaks [1].

Angola has a national vaccination programme, uptake is low and protects against serogroups 1 and 3 [3]. 

CVDPVs can arise in populations who are inadequately vaccinated and where sanitation and personal hygiene is poor. Like wild poliovirus, vaccine derived polio viruses (VDPV) have the potential to cause paralysis in unvaccinated or partially vaccinated individuals [4].

TravelHealthPro Country Information vaccination recommendations for Angola has been updated to reflect this recent outbreak.

Advice for travellers

CVDPV can be transmitted via the faecal-oral route, through exposure to water contaminated by infected human faeces, or by direct person to person contact. You are advised to practise strict food, water and personal hygiene.

Independent of your travel destination, you should be up to date with routine vaccination courses and boosters as recommended in the UK.

If you are travelling to countries reporting recent cVDPV, including Angola, you should make sure you have completed a full course of a polio-containing vaccine. Vaccines used in the UK will provide protection against all types of polio. If your last dose of polio vaccine was given 10 or more years ago, you should have a booster dose before travel to Angola.

Children who are travelling should be up to date with an age appropriate course of polio vaccine.

Other recommendations for polio vaccination apply to certain travellers and are given on the Angola Country Information page: vaccine recommendations.

The polio status of countries is reviewed by World Health Organization on a regular basis and polio vaccination recommendations are subject to change.

Further details on the global polio situation can be found on the Global Polio Eradication Initiative and WHO websites.
