A dairy worker in Texas contracts H5N1 bird flu after contact with infected cows, and suffers eye inflammation. Weeks later, a dairy worker in Michigan begins to cough and then tests positive for the virus. These data and other recent cases of H5N1 suggest that the virus might be evolving to spread more easily to — and among — people. One implication is that while U.S. health authorities say the risk to the general public remains low, that risk could increase quickly. For instance, why isn’t blood testing for signs of the virus among dairy workers now mandatory in all U.S. dairy operations?

The Covid Origins Debate

Did Covid jump from an animal to a person at a food market in Wuhan, China — or leak from a research lab there? — David LeonhardtIn the early days of the pandemic, I was speaking to a variety of U.S. intelligence officials who believed that China was hiding the truth of what happened with Covid. In the name of safety, Chinese officials ordered that coronavirus samples be destroyed. At best, this hampered the later investigation into Covid’s origins, and at worst it was a sign of a cover-up. In this context, some of those intelligence officials believed that people were not paying enough attention to the lab-leak theory.

The Ongoing Mystery of Covid’s Origin

But as the researchers describe it, these apparent contradictions were simply a reflection of their fast-evolving views. It showed that such an RBD had evolved in the wild and might well have gotten into SARS-CoV-2 by recombination, the natural gene-swapping process. The genome was 96.2 percent identical to the SARS-CoV-2 genome as sampled from people during the early days of the pandemic. RaTG13 has attained renown, not just because it constituted strong evidence of SARS-CoV-2’s ancestry in bat viruses but also because the Mojiang mine figures in some of the more lurid scenarios for a lab-leak origin. The inference is that Shi’s team, a year after the mine workers died, may have taken the virus back to Wuhan.

Is malaria an emergency? Is tuberculosis of international concern? I’m neither a public health expert nor a scientist, so I offer a citizen’s opinion: Yes, it’s time to cease calling Covid-19 a public health emergency of international concern. Therefore, Covid is still certainly a public health situation of international concern. We will need to keep improving laboratory techniques and manufacturing capacity for potentially ever-revised Covid vaccines.
Any such bird flu, so deadly, is called highly pathogenic avian influenza, or H.P.A.I. Until this century, these kinds of viruses were virtually unknown among wild birds. For decades after that tern die-off, though, no other influenza so virulent was detected in wild birds. New influenzas did come from wild birds, yes, but in milder form, usually sickening domestic birds little or not at all. The ducks share the rice paddy with wild birds passing through, and some of the chickens are sent live to a local market.
Imani Perry's "South to America: A Journey Below the Mason-Dixon to Understand the Soul of a Nation" has been named the National Book Award winner for nonfiction. The book chronicles the Princeton professor's journey to her native Alabama, putting forth the idea that to better understand America, one must first understand the history and culture of the American South. "'Bama has a National Book Award," Perry said while accepting her award in New York City on Wednesday evening. In her tearful acceptance speech, the 50-year-old award winner said that she writes for "my people." The winners in each National Book Award category receive $10,000, NBC News reports, with nominees chosen by a five-person panel with judges including authors, editors and booksellers.
