Brasília – Ministry of Health admits that there is a high risk of polio ] in at least 312 Brazilian cities – 44 in the state of São Paulo . The alert was made Thursday (28) at a meeting with state secretaries and municipal health officials. "It's a very serious situation," said Carla Domingues, coordinator of the immunization program
. Municipalities that have not reached 50% of immunization coverage are most at risk of polio. "A city with these indicators has all the conditions to retransmit the disease in our country, it will be a disaster for the health as a whole." The last case recorded in Brazil dates back to 1990. Four years later, the World Health Organization (WHO) declared the disease eradicated in the Americas.
The recommendation is that vaccination coverage against polio should exceed 95%. The worst situation is in Bahia, where 15% of municipalities vaccinated less than 50% of children, followed by Maranhão with 14.29%. Across the country, only Rondônia, Espírito Santo and the Federal District do not have high risk cities.
The general picture is very worrying. According to data from the Ministry of Health, last year 22
units of the federation did not reach the coverage considered ideal. Also in 2017, at least 800,000 children did not have the full immunization schedule – which includes three doses of immunization.
"We light the red light," sums up Carla. The concern arises mainly at a time when the entry of the derived poliovirus was again discussed. In Venezuela, health authorities have considered the possibility that a girl has been infected by this viral mutation.
When vaccine drops are administered to the child, the attenuated virus contained in the vaccine may be present in the environment for four to six months. weeks, creating what is called the herd effect. The problem is that during this period, on very rare occasions, the poliovirus may have contact with other viruses, such as rotavirus, mutate and become infected with the virus.
thus creating a new wave of infections. This hypothesis was rejected in the case of the Venezuelan child, but the concern persists.
The president of the Brazilian Society of Immunization, Isabella Ballalai, notes that the risk increases in cases where immunization coverage is lower. "Where the need to maintain vaccination at 95%."
Isabella called the Brazilian indicator "unbelievable and inadmissible". Carla notes that the most significant decline has occurred over the past two years. In an attempt to reduce the risk, the Ministry of Health is scheduled to conduct a national immunization campaign against polio between August 6 and 31.
Other diseases
Carla also emphasizes that vaccination coverage rates in the country are fallen expressive. For example, it mentions vaccines such as measles, rubella and mumps, pentavalent (diphtheria, tetanus, pertussis, haemophilus influenzae type b and polio meningitis) and pneumococcus. . "In none of these cases was there a shortage," he notes
. For her, the indicators show the need to think about what is done at the end of the care. She notes that the vaccination program offers 14 vaccines. "It takes simultaneity to set up a schedule to offer, during a visit to the post, more than one vaccine." In the ideal scheme, he says, parents take the child nine times in the year to the vaccination post. "If it's not done correctly, that number goes up to 10, 11, 12," he notes
. Resistance to give more than one vaccine the same day by health professionals could be enhanced by capacity building. The same thing applies to completing the vaccination forms. Few municipalities follow the recommendation of registering the nominal vaccination. "The notes are made by dose only.This makes it difficult to search for children who are late," says Carla.
Timetable
For her, it also requires greater rationality in the form of offers Vaccines, such as more flexible work schedules of parents. "The stations run from 8am to 11am and from 2pm to 5pm. Not all parents can take their children at these times several times a year. "
The opening of many vaccination rooms, in turn, would be counter-productive." You need scale. Doses should be opened and used quickly. Otherwise, there is a waste. The information comes from the journal O Estado de S. Paulo
