A quadruple whammy of viruses – flu, COVID, norovirus, and respiratory syncytial virus, or RSV – is hitting the U.S. as the year comes to a close. The Centers for Disease Control and ...
The latest numbers show 66 confirmed human cases of bird flu in the U.S. The CDC is taking a holiday break and will resume updates on human cases on Jan. 3. The CDC is taking a holiday break and ...
Variants are expected as “gradual changes to the virus, known as mutations, result in new viruses that look different to your immune system,” the CDC says. But this novelty is what makes it ...
Currently, New Hampshire is listed as having "very high" respiratory virus activity, and 11 states – Arizona, Delaware, Georgia, Idaho, Kansas, Kentucky, Louisiana, Oklahoma, Tennessee, Texas ...
As of September 28, 2024, a new subvariant of Omicron labeled XEC has emerged. The new variant is found in Europe, and in 25 states in the United States of America, including three cases in California.

Norovirus cases are surging across the country this winter, according to Centers for Disease Control and Prevention (CDC) data. There were 91 outbreaks reported by state health departments during ...
The main virus involved in the global outbreak is classified as H5N1 clade 2.3.4.4b, however genetic diversification with other clades such as 2.3.2.1c has seen the virus evolve in ability to cause significant outbreaks in a broader range of species including mammals. [7] [8] [9]
Virus infections start when viral particles bind to host surface cellular receptors. [158] Protein modeling experiments on the spike protein of the virus soon suggested that SARS‑CoV‑2 has sufficient affinity to the receptor angiotensin converting enzyme 2 (ACE2) on human cells to use them as a mechanism of cell entry.
