Polio Virus Detected in Healthy Children in Papua New Guinea
Imagine a tiny germ called poliovirus that can make people sick.
In some places, like Papua New Guinea, health officials found this virus in healthy kids.
This virus came from the polio vaccine, but it changed a bit and can still spread.
Most kids won't feel sick, but they can still pass the virus to others.
Because not everyone in the area has been vaccinated, there's a higher chance of more people getting sick.
The virus can cause different problems, from a simple fever to serious issues with the nervous system.
That's why it's important for everyone to get vaccinated.
cVDPV2 poliovirus was found in stool samples of two asymptomatic children in Papua New Guinea.
The virus was detected during routine checks following an earlier environmental sample.
Low vaccination rates in Papua New Guinea, especially in Morobe Province, are a concern.
The presence of the virus indicates it's circulating within the community, despite children showing no symptoms.
Polio can range from asymptomatic to severe illness; most infections show no symptoms.
