On Saturday, September 10, the Strategic Information Center of the Ministry of Health, an company underneath the Ministry of Health, revealed a danger assertion for the detection of poliomyelitis virus in the United States, and has already put the complete diagnostic community in Brazil into state. awake.

The world is anxiously watching the resurgence of this previous disease that has already plagued so many households: polio amongst youngsters, polio amongst the plenty. An acute infectious disease attributable to a virus that lives in the intestines, known as poliovirus, is transmitted to youngsters and adults by direct contact with feces or secretions that cross by way of the mouth of contaminated folks.

Polio might or might not trigger paralysis. In extreme circumstances, muscle paralysis happens and the decrease limbs are extra affected.

Commission on Certification of Polio Eradication.

The final assembly of this fee was held in Geneva in June 2022 and aimed to evaluation progress in the eradication of wild poliovirus, together with the response to the outbreak in southern Africa and the prevention of the outbreak of vaccinia virus sort 2. Vaccine-derived poliovirus sort 2 (VDPV2) from environmental samples in London, UK in May 2022, subsequent virological and epidemiological analyzes confirmed the circulation of this pressure.

Because there are two vaccines towards this virus, an oral vaccine from our well-known hero Ze Gotinha, an attenuated (weakened) virus vaccine, and an intramuscular vaccine, an inactivated (useless) virus, inactivated. vaccine (VIP). An attenuated virus vaccine, the oral vaccine (VOP), with the virus nonetheless lively to trigger signs, may cause disease in immunosuppressed people. When vaccination is excessive, ie 95% of youngsters underneath 4 years of age are vaccinated, virus circulation is interrupted or drastically diminished and there’s no danger to public well being. The drawback arises when vaccine protection declines and there are extra folks uncovered to the disease in the group.


The American area didn’t have wild virus and vaccine virus, however final week the outbreak of the disease in the United States and the discovery of vaccine virus in the sewage of a particular person recognized with the disease, the ministry mentioned. da Saude issued a danger assertion for Brazil.

It ought to be famous that since the preliminary isolation of VDPV2 in London in May, public well being authorities have been working underneath the assumption that this pressure is circulating. To cease its speedy unfold, quick actions are wanted, comparable to: persevering with to intensify surveillance efforts (together with for potential circumstances of paralysis), figuring out subpopulations or areas with low vaccination protection, and administering extra doses of vaccine to enhance protection. provide.

As polio has been eradicated in a number of areas of the world, and to keep away from paralysis attributable to the virus contained in the oral vaccine (OPV), the WHO recommends that nations like Brazil have a low danger of growing the disease. If disease happens, begin utilizing inactivated vaccine (VIP) as quickly as attainable. As of 2012, the National Program on Immunization (PNI) accepts the VIP vaccine in the first three doses of the first 12 months of life (at 2, 4, and 6 months) and in the OPV booster and annual vaccination campaigns.


In Brazil, it’s time to use solely the inactivated virus vaccine (VIP) for the primary and booster routine, that’s, for all doses. However, since vaccination protection has been low in recent times and primarily due to the rise of anti-vaccination actions throughout the Covid-19 pandemic, a change in technique by Brazilian well being authorities is essential.

Faced with this publicized disaster, WHO joined different organizations, together with Rotary International, in campaigning for a polio-free world. In Espirito Santo, as well as to the well being authorities, Rotary is growing actions to eradicate polio in collaboration with the Ufes Epidemiological Laboratory.

Community involvement and consciousness of the devastating results of the resurgence of this critical disease with penalties related to poliovirus an infection of the spinal twine and mind, which is usually cell and incurable, is a precedence. Expanding vaccination protection is important to cease this evil from making a comeback.

Civil society, dad and mom, guardians and educators ought to deal with polio vaccination and assist cut back the burden of unvaccinated folks. Only collectively we will overcome this disease and check out to remove it fully.
