An alert from the Civil Defense was sent this Wednesday (14/9) to the population of Rio Grande do Sul encouraging children to be vaccinated against polio.
“Civil Defense: RS warns against polio: vaccinate children under 5 years of age by 9/30 and combat the risk of infantile paralysis returning. Take care of our children!”, reads the text, sent by SMS to the 800,000 registered users of service 40199.
The alerts sent usually deal with weather events with risk for the population, but since the covid-19 pandemic, the Civil Defense has supported the Secretary of Health (SES) in public health campaigns. This is the case with the action against poliomyelitis. The State intends to achieve the goal of the National Vaccination Campaign against Poliomyelitis 2022 to immunize 95% of children from one year to four years, 11 months and 29 days.
“The alert we issued today was a request from the Department of Health. Vaccination is important and we participate in this campaign so that children are vaccinated in a comprehensive way”, said the head of the Military House and state coordinator of Civil Defense and Protection, Colonel Júlio César Rocha Lopes.
Until this Wednesday (14/9), 281,611 doses of the polio vaccine were applied in the state, reaching 50.85% of children. Data from the National Vaccination Campaign Against Poliomyelitis 2022 can be followed at this link.
fall in coverage
Vaccination rates below the goals recommended by the Ministry of Health increase the risks for vaccine-preventable diseases, such as whooping cough, polio, measles, mumps, rubella, chickenpox, meningococcal and pneumococcal meningitis, rotavirus gastroenteritis and hepatitis A and B, among others.
Considering the basic childhood vaccination schedule, in the last five years, the targets have not been reached. The 2021 data, considered still partial, indicate that Rio Grande do Sul will be below the projected rates.
In recent years, in Rio Grande do Sul, vaccination against poliomyelitis has not reached the target of 95% coverage. The analysis of the historical series of vaccination coverage from 2017 to 2020 has varied between 75% and 86%.
Poliomyelitis, or infantile paralysis, is an acute contagious disease caused by the poliovirus, which can infect children and adults via the fecal-oral route (through direct contact with feces or secretions expelled from the mouth of infected people), and can attack the system. nervous system and cause acute flaccid paralysis, mainly in the lower limbs.
Basic children’s calendar scheme
- Inactivated polio vaccine 1,2,3 (VIP)
Dose: 0.5 mL intramuscularly
Schedule: three doses (at 2, 4 and 6 months)
- Attenuated Poliomyelitis 1, 3 vaccine (VOP – droplet)
Dosage: two drops, orally
Scheme: booster applied at 15 months of age and at 4 years
Critical risk situation
An analysis by the Pan American Health Organization (PAHO) identified that Brazil, in 2021, was one of the countries on the American continent at high risk of reintroduction of the poliomyelitis virus, along with five others (Argentina, Bolivia, Ecuador, Panama and Paraguay). Four are at very high risk: Haiti, Peru, Dominican Republic and Venezuela.
In Rio Grande do Sul, the analysis showed a worrying scenario, in which 42% of the municipalities in Rio Grande do Sul are at very high risk and 32% at high risk. That is, in 367 municipalities in the state (74%) there is a great risk of a return of polio cases.
For the risk analysis, vaccination coverage, epidemiological surveillance and some health determinants such as access to drinking water and sewage network are considered. This reinforces the need to maintain permanent and effective disease surveillance actions and adequate levels of immune protection for the population.
