More than half the time after the campaign, in Salvador, measles vaccination targets received only 4.8% of visitors immunizations, matching 10,144 children aged 6 months to 5 years. Low numbers occur across the state. According to the Bahia Health Department (SESAB), only 11.7% of Bahia children were vaccinated during the national campaign, which began on April 4 and lasted until June 3. Low loyalty, associated with the emergence of suspected cases of the disease, has alarmed authorities.
Following the outbreak of measles in 2019, Bahia has not recorded a case of the disease since 2020 But in 2022, so far, there are already 52 suspected cases Of these, 27 have been canceled and 25 are still under investigation. Measles is highly contagious and six times more contagious than Covid-19. The disease can lead to death, especially in children under 5 years of age. In 2022, there are already confirmed cases of the disease in at least Sao Paulo and Amapa.
Sesab’s epidemic surveillance strategy, Adriana Dorado, warns of declining vaccine coverage in the state. According to him, in 2019, the percentage was 84.75%; In 2020, the percentage decreased from 78.48% and, in 2021, to 62.31%. So far, in 2022, the rate is at 17.45%.
“These are very small numbers, the norm was at least 95%. This is worrying because, with low levels, from the moment the virus enters the territory, we will inevitably live with an outbreak. “To do
Salvador’s Secretariat has also issued a warning about low-vaccination coverage against measles. In the capital, in 2019, coverage was 71.92%. The following year, at 68, 20%. In 2021, a sharp decline to 24.11%. With the national campaign in 2022, which began on April 4, not only was child immunization reduced in the capital.
59-year-old health professionals can also be vaccinated, but, so far, only 23,153 of them have been vaccinated, which corresponds to 16.24%. In Bahia, the vaccination percentage of health professionals in the campaign is 21.05%, which represents 78,815 people. Note that the vaccine is being administered to children as a booster, meaning that those who have already been vaccinated will also have to go to the clinic again.
According to Dwayne Lemos, immunization coordinator at the Municipal Health Department, the best way to prevent the disease is to get vaccinated. The manager invites parents and guardians to come to the health centers to update their children’s vaccine status.
“An optimal immunization coverage is crucial to breaking the chain of infection in our city and preventing the spread of the virus. Unfortunately, we still have very little adherence to the strategy and this worries us even more. Parents and guardians need to take their children to a health center for regular immunization. “He explained.
The cases are under investigation
The 25 cases of measles under investigation in Bahia have been distributed in the municipalities of Lauro de Freitas, Camacari, Agua Freya, Epiau, Alagoinhas, Apora, Bareiras, Cacule, Castro Alves, Corintina, Ibotirama, Iresa, Tapero and Vera Cruz. According to Sesab, the cases are being monitored and once confirmed, the state will enter the alert level 1 according to the measles contingency plan.
In Vitória da Conquista, three cases are under investigation. In all, there are already 14 suspects in the municipality, of whom 11 have been dismissed. The municipality’s epidemiological surveillance has issued a warning to health units and strengthened the recommendation to health professionals and the public to be fully vigilant in any suspected case of skin rash-related febrile exanthematus.
“We are waiting for the results of the other three. We are already investigating the vaccine blockade in the area, that is, we are vaccinating people who come in contact with the suspects, “said Anna Maria Ferrez, director of the municipality’s health surveillance. The agency blames growth for resuming school life and providing less vaccines against the disease. In 2021, the vaccination coverage in the municipality was 63.29%. This year, coverage is 10.71%.
Three cases are under investigation in the Vitória da Conquista, and a total of 52 cases have not yet been filed in the state created by them. According to the secretariat, the three should be added to the system later this week, as well as other municipal cases that were identified during the consolidation and active search.
In Taperoá, three cases are under investigation, including the results of the first serological sample reactive (positive) for measles. “For three of them, a second serology sample will be collected to evaluate the production of antibodies and the PCRT will be processed by the Fuecruz National Reference Laboratory in Rio de Janeiro,” Adriana Dorado told AFP.
Sesab’s epidemic surveillance strategy explains the already dismissed case. “First, the serology test is done and if positive, the PCR test. We have suspected cases in some municipalities that had preliminary serology results that were responsive to measles. We imagine that these are from cross-reaction between viruses, that is, when a person is infected with another virus, such as dengue or hand-foot-mouth syndrome, and when it is transmitted with measles it gives a false reactive result. Virus. “, It says.
Will Hum come back?
In 1992, Brazil implemented the National Measles Eradication Plan and in 2016 was able to obtain the Pan American Health Organization (PAHO) certificate. But in 2018 there was a shock with the re-entry of this disease in the country. In Bahia, there were three cases of measles in Ilheus in 2018 and in 2019, there was an outbreak with 80 cases in 25 municipalities.
The last measles cases in the state were recorded in 2020 (in 7 cases), distributed as follows: Loro de Freitas (2), Juazeiro (1), Belo Campo (1) and Paripiranga (2). In 2021, there were no confirmed cases of measles in the state. In recent years, despite the outbreak, no deaths have been reported from the disease, according to Sesab.
What is hum?
According to the Ministry of Health, measles is a highly contagious disease caused by a virus called morbilivirus, which can be extremely dangerous, especially for children under 5 years of age, causing sequelae or death. The disease is spread through the air and is transmitted from one person to another through coughing, breathing, talking or inhaling secretions from the nose and mouth.
“It is a disease of high infectivity and high mortality rate, especially in children under 5 years of age, but also in young people between 20 and 29 years of age. The risk of contracting the measles virus is 1 in 18, meaning that an infected person can infect another 18 people. Compared to the Covid-19, for example, the infection 1 to 3 “Highlight Adriana Dourado.
In children, some possible complications are: pneumonia (1 in 20 children with measles), acute otitis media (1 in 10 children get measles and this can lead to permanent hearing loss), acute encephalitis (1 in 1,000 children). Can develop (complications and 10% of them may die) and death (between 1 and 3 per 1,000 sick children).
Complications can also occur in adults. Pneumonia is predominant. Another caveat for pregnant women: Women of childbearing age (10 to 49 years) who have not been vaccinated before pregnancy may have a premature birth and may have low birth weight. It is important to get vaccinated before pregnancy, as the vaccine is contraindicated during pregnancy.
The only effective protection against measles is vaccination, inhibiting the transmission of the virus and eradicating the disease. Types of vaccines are: Dual viral – protects against measles and rubella viruses. It can be used to block vaccines in an outbreak situation; MMR – protects against measles, mumps and rubella viruses; Viral Tetra – Protects against measles, mumps, rubella and chickenpox viruses.
According to the Sesab epidemiological surveillance technique, infants receive the first dose at 1 year and the second dose at 15 months. “Ideally, people up to the age of 29 have two doses. From 30 to 59, you should have at least one dose. For the elderly, each case needs to be evaluated by a doctor, “he said.” It is important to note that if a person does not receive the dose in childhood, they can and should seek medical attention. Those who have measles and have not been vaccinated should also be vaccinated. Should.
