Researchers have found an increased risk of death in young and middle-aged adults in Brazil after being infected with COVID-19.
Researchers have pointed out that Brazil is currently suffering from a “fatal surge” of COVID-19 infections. This is due to the spread of a new strain known as P.1 (B.126.96.36.199).
They examined public COVID-19 data from the state of Parana in southern Brazil (the largest state in the southern half of the country) with a total of 553,518 positive cases between September 2020 and March 17, 2021. I did.
their reportPublished on medRxiv on April 2, prior to peer review, the proportion of deceased patients was found to be stable or declining between September and January. However, since February, mortality has increased in almost all groups over the age of 20.
From January to February, these rates tripled from 0.04% to 0.13% in COVID-19 patients aged 20-29 years and doubled in 30-39 years, 40-49 years, and 50-59 years. became.
“Individuals between the ages of 20 and 29 diagnosed in February 2021 had a risk of death that was more than three times higher than those diagnosed in January 2021,” the researchers said. ..
“In summary, these preliminary findings suggest that the mortality rate of young and middle-aged adults will increase significantly after the identification of a new SARS-CoV-2 strain that is endemic in Brazil. , This should cause a public health warning. “
The cause of the increase in infection rates among the young Brazilian population is unknown, but medical professionals, coupled with the British variant, are the first P.1 variant to emerge in the city of Manaus at the end of last year. It suggests that the limited vaccine is contributing. To rise.
Government data Last month, more than 2,030 Brazilians between the ages of 30 and 39 died of COVID-19, a disease caused by the CCP (Chinese Communist Party) virus. This is more than double the number recorded in January. Of the deaths in their 40s, about 4,150 died in March, compared to 1,823 in January. For people between the ages of 20 and 29, the number of deaths surged from 242 to 505.
Local doctors Told to CNN Last week, young Brazilians became more ill after being infected with COVID-19 than during the previous pandemic wave.
The P.1 strain is characterized by mutations associated with higher viral infectivity and greater resistance to antibodies, but experts need further research to verify the “compatibility” of the mutant virus. Is warning.
“Last year there was a more important elderly patient. Now it’s completely distinct. We’re dealing with a significant number of critically ill patients in their 30s and 50s,” said Geturio Vargas Hospital in Manaus. Dr. Ammenezes said. Al Jazeera..
