Here's a roundup of recent news stories about the pandemic:
Many drugstores offer coronavirus antibody tests. But they're often a poor indicator of how protected you are from Covid-19, because different people can be protected from infection with different amounts of antibodies. The test also should not be used instead of a PCR or rapid-antigen test, because it can't tell whether you're currently infected.

Though the Omicron surge seems to be waning, rural hospitals have had a tough time with it and resources are still stretched thin. One Missouri hospital built a makeshift intensive care unit for a critical patient with supplies from Walmart after failing to find a single ICU bed at 19 larger hospitals in the region. And monoclonal antibody treatments are in such short supply that many hospitals use a lottery system to determine who gets them.

A right-wing journalist who was hospitalized with Covid-19 showed social-media followers a prescription for ivermectin, an anti-parasitic drug that has been baselessly promoted as a Covid cure. His testimonial
