Over 33 Million Children Vaccinated Against Poliovirus

Globally, kids remain at risk of wild polio type 1 if the polio virus is not eradicated in the last remaining areas in which it is still circulating.

Across southern African countries, over 33 million kids are vaccinated against poliovirus type 1, said the World Health Organization (WHO).

A total of nine wild poliovirus cases have been reported so far, with one in Malawi and eight in neighbouring Mozambique since the declaration of an outbreak on February 17, 2022, in Malawi, reports Xinhua news agency.

Poliomyelitis - About
Polio is an infectious disease caused by the poliovirus. It results in paralysis and generally affects people of all age groups, children being more susceptible

‘The WHO Emergency Committee has declared that the risk of the international spread of poliovirus remains a public health emergency of international concern.’

The last confirmed case to date was in August 2022 in Mozambique.

The wild poliovirus in Malawi and Mozambique originated from Pakistan, one of the two last endemic countries, according to the WHO regional office for Africa, based in Brazzaville, the capital of the Republic of the Congo.

Concerted emergency response launched following the outbreak in 2022 has helped increase protection among children through vaccines in Malawi, Mozambique, Zambia, Tanzania and Zimbabwe.

The countries have also ramped up disease surveillance and community mobilization to help find cases and halt the virus.

Post-Polio Syndrome - Symptoms, Causes, Diagnosis and Treatment
Post polio syndrome occurs a long time after an early attack of poliomyelitis virus. Gradual progressive weakening in muscles, fatigue, joint pain and a decrease in the size of muscles are key symptoms.

To date, 19 vaccination rounds have been concluded in the most at-risk areas, and at least five more are planned for 2023 in the five countries.

"Southern Africa countries have made huge efforts to bolster polio detection, curb the spread of the virus and ensure that children live without the risk of infection and lifelong paralysis," said Matshidiso Moeti, WHO regional director for Africa.

Polio was one of the dreaded diseases that left its victims paralyzed and disabled for life. Test your knowledge on this condition, which hopefully will soon be history!

"We continue to support the polio control efforts across the region so that every child receives the protection they need."

Additionally, more than 10 new environmental surveillance sites have been set up over the past year in the affected countries with support from WHO. The fully operational sites are playing a critical role in the efforts to detect silent circulating poliovirus in wastewater.

After 10 years, a young patient with poliovirus has been detected in the USA, who had not been vaccinated and received the oral polio vaccine (OPV).

"Response teams have worked intensely in the fight against polio not only in Malawi but in the rest of the neighboring countries in a coordinated manner. We will not rest until we reach and vaccinate every child to stop polio transmission," said Emeka Agbo, Acting Country Coordinator for the Global Polio Eradication Initiative in Malawi.

Reaching all households where eligible children live is critical to protect them against the risk of paralysis.

The national health authorities, with support from the Global Polio Eradication Initiative, are paying efforts to map cross-border communities, migratory routes, border crossings and transit routes.

Polio is highly infectious and affects unimmunized or under-immunized children.

In Malawi and Mozambique, the disease has paralyzed children younger than 15 years. There is no cure for polio, and it can only be prevented by immunization.
