The recent history of measles
In September 2016, the measles virus was declared eliminated in the Americas region. In 2018, there was an outbreak, starting in the north of the country, which is still in the five Brazilian regions. After 12 months of circulating the virus, Brazil lost the title of disease-free country. Also in 2018, the state of Rio de Janeiro also experienced an outbreak and, as of 2019, again presents a large number of confirmed cases. In 2020, there has been a significant increase in reported cases.
Rio de Janeiro is one of four states in the country where cases of the disease were recorded in 2022. One of the problems is low vaccination coverage, which, according to a survey in August, amounted to 44.53%. In at least 11 municipalities, the proportion does not reach 25%. The teams are doing a quick monitoring of the coverage in the municipal areas.
This year, from January 1 to August 31, 2022, 164 suspected measles cases were reported among the state’s residents: 2 confirmed cases, 147 ruled out and 14 under investigation. Only two of the 92 municipalities have a vaccination coverage of more than 95% against the disease caused by a highly transmissible respiratory virus for which a vaccine has been available since the 1960s.
