Disinformation campaigns about vaccines against Covid-19 have negatively interfered with the immunization routine of Brazilian children, previously a success over the years.
On the 21st of this month, health officials in Rockland County, located northwest of New York, announced that a 20-year-old male resident of the area tested positive for poliomyelitis, also known as infantile paralysis. .
Upon positive identification of the patient for polio, the population of the city immediately began to receive the Salk anti-polio vaccine, introduced by the United States in 1950.
Doctor Bryon Backenson, from the State Department of Health, as reported by the American press, reported that there was no indication of additional cases.
The patient was discovered because health officials alerted county doctors to possible cases of a neurological disease, acute flaccid myelitis, which has symptoms similar to polio. Submitted to laboratory tests, the patient tested positive for poliomyelitis.
The Sabin and Salk vaccines entered the medical routine in 1960. Polio was not treated and still is not treated today. Therefore, it is a disease with a strong possibility of prevention and priority for eradication.
According to the WHO (World Health Organization), polio mainly affects children under the age of five. Thanks to polio vaccination, cases have decreased by more than 99% since 1988, from about 350,000 occurrences in 125 countries to 6 cases in 2021.
In every 200 infections, one causes irreversible paralysis; among them, 5% to 10% cause respiratory muscle paralysis. In the past, patients were placed in a device (steel lungs) at Hospital das ClÃnicas that helped them breathe.
