According to ITps, the new wave has a different pattern than what was observed in 2022, when there was a period of six to seven weeks of low positivity (below 10%). This time the break was curto.
“This probably occurred because the previous and current waves were caused by subvariants with very different genetic profiles. Furthermore, events with large crowds may also have accelerated the replacement of BQ.1 by XBB”, says ITpS scientific researcher Anderson Brito, who coordinates the monitoring of SARS-CoV-2 variants.

In relation to age groups, the percentage of positive tests is higher among older people, but there was growth, between the end of January and the end of February, in practically all of them:
- 0 to 4 years – From 5% to 7%
- 5 to 9 years – From 5% to 6%
- 10 to 19 years – From 8% to 13%
- 20 to 29 years – From 11% to 24%
- 30 to 39 years – From 16% to 27%
- 40 to 49 years – From 14% to 32%
- 50 to 59 years – From 19% to 39%
- 60 to 69 years – From 15% to 37%
- 70 to 79 years – From 18% to 34%
- Over 80 years old – From 18% to 29%
Covid-19 in the states
Goiás and the Federal District continue with low positivity rateswhile in São Paulo (32%) and Rio de Janeiro (30%), the percentage is high.
In other states, the level of demand for tests makes analysis impossible. It is important to remember that Covid-19 outbreaks do not occur synchronously in the country.

Vaccination
It is important to remember that the increase in covid positivity will not necessarily lead to an increase in hospitalizations, because of vaccines. 😉
Therefore, it is important to warn: pay attention to the Covid-19 vaccination schedule and look for health centers for immunization with booster doses.
On the 27th, the Ministry of Health launched the National Vaccination Movement with the bivalent vaccine, starting with the most vulnerable.

Real Time
O All for Health Institute has been monitoring the arrival and dissemination of Ômicron in Brazil since December 2022 — this is the 23rd report —, in partnership with private laboratories.
The objective is to provide public authorities, the press and society with information quickly to help make health decisions.
At the same time, ITpS also monitors the circulation of respiratory viruses in the country. The two reports are released alternately.
