The Oswaldo Cruz Foundation (Fiocruz) presented last Tuesday (3) a study, still nearing completion, which warns of the increase in the number of hospitalizations of the elderly for Severe Acute Respiratory Syndrome (SRAG by Covid-19) in the state from Rio de Janeiro.
The increase in the number of cases occurs after about four months showing a drop in hospitalizations. Even so, the analysis indicates that the age groups 60 to 69 years and 70 to 79 years are still in a much better situation than presented in previous peaks. The biggest concern is with the population aged 80 and over.

The study highlights that the population of children aged zero to nine years is at the worst moment of the pandemic. The 30 to 39 age group, in spite of having registered an improvement, is in a more serious situation than at the peak at the end of last year.
The investigation is by the research group for Epidemiological Surveillance at Fiocruz (Mave/Fiocruz) and the Covid-19 Observatory. The projections are based on the Fiocruz Epidemiological Surveillance Information System (Sivep-Gripe), of the Ministry of Health.
According to the study, the data indicate that the scenario is still very serious. The tension is now also found in the population with good vaccination coverage, but whose effectiveness is lower, which is that of the elderly aged 80 years or more.

In this age group from 80 years onwards, there are some aggravating factors. Among them are the still high community transmission, lesser effectiveness, longer time since the second dose and possible loss of immunity (immunosenescence) due to age.
