Which countries were identified as high risk for Polio virus transmission?
Polio transmission is currently concentrated in a limited number of countries and specific regions within them. High-risk areas are often defined by ongoing outbreaks, low vaccination rates, or instability. Factors like conflict, misinformation, and pandemic-related vaccine stops keep certain places on the high-risk list.
What the research says
Pakistan is identified as one of the few countries where poliovirus transmission still persists despite global eradication efforts 8. In this country, high-risk areas include regions where misconceptions about vaccines lead to refusal, hindering the program's success 8.
In Ethiopia, the country remains at risk of outbreaks, particularly in pastoralist communities and areas affected by conflict 1. These specific zones face challenges that make sustaining surveillance and preventing transmission difficult.
The risk of polio has also increased in Africa and the Philippines due to disruptions in routine immunizations caused by the COVID-19 pandemic 4. These disruptions elevate the risk for increases in vaccine-preventable diseases like polio in these specific regions 4.
Australia remains at risk of importing the virus from endemic countries, and specific local areas with high arrivals from those countries and low vaccination coverage are identified as at increased risk 6.
What to ask your doctor
- Which specific regions or countries are currently listed as high-risk for polio transmission?
- How might recent global events or travel to certain areas affect my personal risk of exposure?
- What are the current vaccination recommendations for travelers to high-risk polio areas?
- Are there specific signs of polio I should watch for if I travel to a high-risk zone?
