US subspecies COVID-19 cases increased.Air travelers who need a negative test

The Centers for Disease Control and Prevention (CDC) has announced a new order that will come into effect on January 26. All air travelers arriving in the United States must test negative for COVID-19 within 3 days of departure. In addition to the negative test, travelers must be quarantined on arrival for 7 days and take a second COVID-19 test within 3-5 days of landing in the United States.

“SARS-CoV-2 virus variants continue to emerge in countries around the world, and there is evidence of increased infectivity for some of these variants,” said the CDC. Media statementyesterday. “Because the United States is already booming, air passenger testing requirements can help slow the spread of the virus when tackling immunization of Americans.”

Passengers must provide the airline with written evidence of negative test results or a document certifying that they have recovered from COVID-19.

“Testing does not eliminate all risks,” CDC Director Robert Redfield, MD, said in a statement. “But when combined with staying at home and routine precautions such as wearing masks and social distance, it makes travel safer and healthier by reducing spread on planes, airports and destinations. , You can do it more responsibly. “

Ohio researchers identify new variants

COVID-19 mutants, including the B117 mutant that originated in the United Kingdom, are already circulating throughout the United States. Today, Ohio-based researchers say they have discovered a new variant that grows naturally in the state and is probably behind the rapid spread of the virus in Columbus.

Researchers at Ohio State University haven’t released their findings yet, but say the strain first appeared in late December. Like B117, this strain appears to be more susceptible to infection than the original virus, SARS-CoV-2, but the vaccine should still be able to provide protection.

“This new Columbus strain has the same genetic backbone as the previous cases we studied, but these three mutations represent significant evolution,” said Vice-Chairman of the Molecular Pathology Division. Dr. Dan Jones, a research leader, said. Press release.. “We know that this change is not from the UK or South Africa branch of the virus.”

Possible delays in Johnson & Johnson vaccine

The emergence of mutant strains occurs when the country embarks on a large vaccine campaign with two COVID-19 vaccines, one from Pfizer and BioNTech and one from Moderna.Third COVID-19 vaccine made by Johnson & Johnson, Will be online in March.today New York Times Phase 3 results from trials with the vaccine were reported to be expected in the coming weeks.

The Johnson & Johnson vaccine is promising because it requires only one dose and can be refrigerated for several months at a time. However, the company said earlier this week that production delays could prevent it from delivering the promised 12 million doses by the end of February. Instead, the company is likely to have a million single-digit doses ready by the end of next month.

According to the CDC COVID data tracker, 27,696,150 COVID-19 vaccine doses were distributed in the United States from December, with 9,327,138 doses, of which 951,774 were given at nursing homes. Arizona, Alabama, Arkansas, Mississippi, Georgia, and South Carolina are the states with the lowest immunization rates.

In related news, the U.S. government has signed an agreement to purchase an additional 1.25 million doses. Regeneron antibody cocktail. The dose is used to avoid hospitalization of patients with mild to moderate COVID-19 symptoms.

CDC: More cases of children as school resumes

According to Johns Hopkins COVID-19, the United States yesterday reported 215,805 new COVID-19 cases and 4,327 deaths. Tracker.. There are 131,326 COVID-19 patients in US hospitals. COVID tracking project..

In total, the United States reported 22,987,370 confirmed cases of COVID-19. 383,113 people died..

In the United States, as schools reopened, more children became infected with the virus, but outbreaks across schools are limited. CDC..

According to the CDC, a total of 2,871,828 cases confirmed in the COVID-19 laboratory in children, adolescents, and young adults aged 0 to 24 years were reported between March 1 and December 12, 2020. It was.

Young adults aged 18 to 24 accounted for the majority of cases. Children and adolescents aged 14 to 17 account for 16.3%, 11 to 13 years 7.9%, 5 to 10 years 10.9%, and 0 to 4 years 7.4%.

“Evidence from low incidence of infants and available studies is that the risk of introducing and transmitting COVID-19 among children associated with the reopening of nurseries and primary schools is the reopening of high schools and higher education institutions It suggests that it may be lower than that, “the author said.
