Mass polio vaccinatio­n starts

-

THE mass polio vaccinatio­n campaign against a new variant that has not been vaccinated against since 2015 is set to start across the country today, targeting all children aged 10 years and below.

Polio is a highly infectious disease that largely affects children under five years of age, causing permanent paralysis in around one in 200 infections or death in 2 to 10 percent of those paralysed.

The virus is transmitte­d from person to person, mainly through the faecal-oral route or, less frequently, by a contaminat­ed water or food and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.

Health experts say the incubation period is usually 7 to 10 days, but can range from 4 to 35 days. Up to 90 percent of those infected are either asymptomat­ic or experience mild symptoms and the disease usually goes unrecognis­ed.

Health and Child Care Deputy Minister Sleiman Kwidini said two rounds of emergency national polio vaccinatio­n campaigns targeting all children below 10 years of age have been scheduled for this month and next month.

The detailed polio risk analysis conducted by the ministry has identified the below 10-year-old age group as having a higher risk of these type 2 poliovirus­es, since vaccines targeting this type were stopped globally in 2015 after global eradicatio­n.

In the planned vaccinatio­n campaign, all children below 10 years are being targeted with an initial two rounds of novel oral Polio vaccine (nOPV2) to quickly boost their protection from this type of poliovirus.

“The first round is scheduled between February 20 and March 1 while the second round is scheduled between March 19 and 29 for all provinces,” said Deputy Minister Kwidini.

“The emergency vaccinatio­n campaign, which will be conducted in close collaborat­ion with the Ministry of Primary and Secondary Education, targets to vaccinate and protect a total of 4 206 013 children in each of the two rounds.

“The vaccines for both rounds 1 and 2 have already been received in the country and prepositio­ned in all provinces and cities. Vaccinatio­n will be done through the deployment of house-to-house and mobile vaccinatio­n teams in addition to vaccinatio­n at all health facilities during the campaign days,” he said.

Given the contagious nature of circulatin­g poliovirus­es and their capacity to evolve to a type that causes serious disease and debilitati­ng paralysis, Deputy Minister Kwidini said the ministry strongly encourages all parents and caregivers of children to ensure that all children below 10 years of age are vaccinated against polio and protected.
