Deaths from the virus were also surpassed by the 782 deaths caused by heart attacks. From the week of January 16 to 22, when 1,976 deaths were recorded, covid had been leading the ranking of deaths. At the time, Brazil was experiencing the height of the third wave, caused by the strong circulation of the Ômicron variant and the effects of the end-of-year festivities. The peak was from January 30 to February 5, when 6,641 died from Covid-19.
In the accumulated result for this month of March, until the 22nd, covid-19 also appears in third place, with 3,549 official death records, behind stroke, with 4,453, and heart attack (4,157 deaths). Since April 2020, this is the second time that Covid-19 has dropped from the top of the disease fatality ranking. The previous one was in the period from October 17, 2021 to January 15 of this year.
The data were computed based on the date of death in the registry, so the numbers may be different from those calculated by the consortium of communication vehicles, of which Estadão is a part, and by the one indicated in the bulletins of the Ministry of Health.
Data from the Ministry indicate that there has been a 77.7% drop in the moving average of cases since February 5, when the pandemic reached its historic maximum in cases, recording an average of 183,000. According to the folder, the drop is mainly due to the broad vaccination campaign against covid-19, which made the immunizer reach 91.38% of the population over 12 years of age with the first dose, and 85.35% of the same public with the first dose. the second application or single dose.
“The Ministry advises Brazilians to take the booster dose. Research from the University of Oxford indicates that this increases immunity against disease by up to 100 times,” she said.
so far, according to the folder, 41% of the public has taken the reinforcement. A survey by the Secretariat for Combating the Covid-19 Pandemic (Secovid) of the Ministry of Health points out that 59.4 million Brazilians are ready to receive the booster dose, however, they have not yet returned to the vaccination posts. The same survey indicates that the completion of the vaccination schedule is pending for 17.6 million people, who only received the first dose.
It’s too early to declare an end to the pandemic, says expert
Infectologist Raquel Stucchi attributed the significant improvement in the spread of covid-19 to the advance of vaccination, but said that it is still too early to decree the end of the pandemic. “These are the effects mainly of the third dose for everyone over 18 years old and the fourth dose for the elderly, in addition to the period of termination of the original Ômicron variant (BA.1). We need to wait and see if Omicron BA.2 will increase circulation here as it did in Europe. The expectation is that this variant could be responsible for a new wave of cases, so we have to wait,” she said.
She recalled that vaccine coverage, not only in Brazil, but worldwide, does not provide a good margin of safety regarding the new variants. “In addition, we are having difficulty, in many places, with vaccination in children and with the adherence of those under 50 to the third dose. This makes it possible for us to keep circulating new variants,” she said.
According to her, it is necessary to promote the vaccination of children, the third dose for everyone aged 18 or over, and the fourth dose, or the first dose of 2022, for all the elderly in the country, in order to prevent BA.2 start to dominate. “It is also necessary to incorporate into the SUS (Unified Health System) some medications already approved by Anvisa (National Health Surveillance Agency) that allow a reduction in the risk of evolution of severe forms of covid for those populations that are known to respond poorly to the vaccine, which are the elderly and the immunocompromised,” he said.
