CNN —The avian flu virus isolated from a hospitalized teenager in Vancouver has mutations in key areas that could help the virus spread more easily in humans, scientists say. But scientists say the genetic changes are a reminder of what the virus is capable of if it continues to spread. The H5N1 bird flu virus that infected the teen, who is in critical but stable condition, is not the same strain that is transmitting in dairy cattle in the United States. The three mutations are at positions in the virus’ genome that Bloom and other scientists have determined would allow it to attach more easily to human cells. Most of the human H5N1 infections reported in the United States have had red, inflamed eyes as an early symptom, suggesting that’s where the virus entered the body.

By Robin Foster HealthDay Reporter(HealthDay)TUESDAY, Nov. 28, 2023 (Healthday News) -- The prevalence of a highly mutated COVID variant has tripled in the past two weeks, new government data shows. Now, nearly 1 in 10 new COVID cases are fueled by the BA.2.86 variant, the U.S. Centers for Disease Control and Prevention reported Monday. Scientists first warned of the highly mutated variant back in August, but it has since spread in several regions of the United States. The CDC also noted that BA.2.86 variant poses a "low" public health risk. But the CDC data released Monday did show that emergency department visits linked to COVID-19 have begun to climb nationwide.

CNN —The US Centers for Disease Control and Prevention is expanding its infectious disease surveillance program at four major US airports to more than 30 pathogens, including flu, RSV and other respiratory viruses. The program currently operates Covid-19 surveillance at seven major international airports in the United States. The traveler surveillance program was introduced in 2021 when the CDC began collecting nasal swab samples from anonymous international travelers arriving at participating airports who volunteer to get swabbed. The program has collected samples from travelers from more than 135 countries and has sequenced more than 14,000 samples for further analysis. The wastewater program, which was introduced in August 2022, collects wastewater from a single plane using a custom-made collection device.

A new study from the Centers for Disease Control and Prevention warns that COVID-19 hospitalization is a “continued public health threat” that predominantly affects adults ages 65 and older. The study looked at hospitalizations from January to August and found that adults ages 65 and older accounted for 63% of all hospitalizations associated with COVID-19. Nearly all hospitalized individuals ages 65 and older had two or more underlying medical conditions. Despite the issues, uptake of the shot is likely to be significantly higher than the last round of boosters. Broken down by age group, about two-thirds of adults ages 65 and older are likely to get the vaccine.

CNN —This year’s Nobel Prize in physiology or medicine has been awarded to Katalin Karikó and Drew Weissman for their work on mRNA vaccines, a crucial tool in curtailing the spread of Covid-19. The Nobel Prize committee announced the prestigious honor, seen as the pinnacle of scientific achievement, in Sweden on Monday. Rickard Sandberg, a member of the Nobel Prize in medicine committee, said, “mRNA vaccines together with other Covid-19 vaccines have been administered over 13 billion times. They sold their car, Karikó told The Guardian, and stuffed the money – an equivalent of about $1,200 – in their daughter’s teddy bear for safekeeping. Weissman told CNN that their technology is much more efficient than traditional methods of producing vaccines.

One negative test on the first day of symptoms, especially with the rapid antigen test, is not determinative. The virus that causes Covid-19 infection is a simple scrap of RNA that cannot survive without a living cell to support it.

So if people are less likely to be hospitalized or die from a Covid-19 infection now, has the danger passed? Through genetic bad luck, some people may just be at higher risk of serious reactions to Covid-19 infections, and they probably wouldn’t know it. Researchers defined it as any new or continuing symptoms more than 90 days after a Covid-19 infection. Based on his experience treating long Covid patients, Griffin said that the percentage reported in the Australian paper seems high. Earlier in the pandemic, pediatric infectious disease specialists were on the lookout for a rare complication of Covid-19 infection in kids called multisystem inflammatory syndrome in children, or MIS-C.MIS-C starts two to six weeks after a Covid-19 infection.

REUTERS/Shannon Stapleton/File Photo Acquire Licensing RightsLONDON/CHICAGO, Aug 24 (Reuters) - A highly mutated COVID variant called BA.2.86 has now been detected in Switzerland and South Africa in addition to Israel, Denmark, the U.S. and the U.K., according to a leading World Health Organization official. It has since been detected in other symptomatic patients, in routine airport screening, and in wastewater samples in a handful of countries. That the known cases are not linked suggests it is already circulating more widely, particularly given reduced surveillance worldwide, she said. There have been nine such cases detected as of Aug. 23 and the variant was also found in wastewater in Switzerland.

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.

However, the vaccine is not based on mRNA and is administered through intramuscular injection, according to the MHRA and SK bioscience.

They also mostly agree that many of the earliest known infections and deaths clustered around a wildlife market in Wuhan, China. Others suspect the pathogen somehow leaked from a Wuhan laboratory, 27 km from the market, where researchers study bat viruses. One concentration of jump zones includes a region of mountains and lakes about 175 km southeast of the Wuhan market. In late 2002, the SARS-CoV-1 virus emerged in Guangdong province, in southern China, and became the SARS pandemic of 2003.
