A new study published on Monday (21) shows that Manaus (AM) has reached the so-called herd immunity, leading to a drop in the number of new confirmed coronavirus cases in the city.

According to researchers, the peak of people immunized in the city was in June, with 51.8% of the population showing antibodies. After correcting false negatives, up to 66% of Manaus's population would have been infected with Sars-CoV-2 (in the most optimistic hypothesis).

However, more than 130,000 people were infected, and nearly 4,000 lost their lives during the explosion of cases and over the past six months, according to the latest press consortium data.

The study was carried out by Brazilian researchers in partnership with scientists from Harvard (USA), Imperial College (United Kingdom), and Oxford University (United Kingdom), in addition to institutes such as Ipea (Institute of Applied Economic Research) and Fiocruz (Foundation Oswaldo Cruz).

The capital of Amazonas was one of the cities most affected by the pandemic. The first case was officially registered on March 13. A month later, there were more than 3,000. As of September 15, the capital had more than 45,000 cases and at least 2,435 deaths.
