Can people be naturally immune or resistant to COVID-19?
More than two years into the COVID-19 pandemic, most Americans have some immunity against the virus — either by vaccination or infection, or a combination of both. But there have been some rare cases in which certain unvaccinated people seem to have been able to dodge the virus despite being repeatedly exposed to it. This has raised the question of whether it is possible that some people are simply immune or resistant to COVID-19 without having had the virus or a vaccine.news.yahoo.com

Study: Children nearly 60% more likely than older adults to spread COVID-19
GAINESVILLE, Fla. – A new epidemiological study from the University of Florida found that while children are less susceptible to COVID-19, they can be nearly 60% more likely than adults over 60 to infect exposed family members. The overall contribution of child cases to household transmission was still limited, the study determined, as children were isolated faster than adults who were infected. Older adults were more likely to become infected than younger household members, especially those under age 20. While children were less susceptible to COVID-19 infection than adults and they generally experienced less severe symptoms, they were just as likely to develop symptoms as adults. “I recommend following CDC guidelines and taking extra caution when a household or family member is infected,” Yang said.
EXPLAINER: China's claims of coronavirus on frozen foods
China has stirred controversy with claims it has detected the coronavirus on packages of imported frozen food.

Frozen shrimp imported from an Ecuadorian company was banned for one week on Tuesday in a continuing series of such temporary bans. Experts say they generally don’t consider the presence of the virus on packaging to be a significant health risk. “I’ve seen no convincing data that SARS-CoV-2 on food packaging poses a significant risk for infection,” he said.
