As Omicron Replaces Delta, “Dark Days Ahead For Hospitals”, Warn Experts

Highly contagious variants of the omicron have cleared delta strains across the U.S., but the supposed rise of milder forms of Covid-19 has so far done little to ease the burden on hospitals.

Rochelle Walensky, director of the Centers for Disease Control and Prevention, said Tuesday that omicron variants account for about 98 percent of cases. The figure is based on data for the week ending Jan. 8 and represents a significant increase from two weeks ago, when omicron accounted for 71.3% of cases.

Omicron’s high infectivity combined with immunity built up by some people against the delta through vaccination and exposure makes conditions favorable for the “milder” variant, said David Wall, a professor at North’s Institute for Global Health and Infectious Diseases. Chapel Hill, Carolina. But experts warn that contracting any variant of Covid-19 is a major problem for those who remain unvaccinated or have other health problems. Without intervention, the data portends dark days for the health care system, they say, which has stretched to its limits.

In many parts of the U.S., the health care system is “collapsed under the weight of Covid patients,” said Neil Sehgal, a professor at the University of Maryland School of Public Health. “I’m starting to wonder if this is a week of collapse for the healthcare system.”

The latest CDC Nowcast data predicts that omicron will dominate the number of cases in every region of the country. While early-hit areas like New York City appear to have peaked in infections, most cities continue to surpass previous records and hospitalizations are soaring.

Covid infection linked to more type 1 diabetes in kids and teens: Study

Two studies that did not definitively resolve the question of whether the coronavirus can cause the chronic disease of diabetes found that Covid-19 in children and adolescents appeared to increase the chance of acquiring diabetes. Over two years after the pandemic’s commencement, researchers from the Norwegian Institute of Public Health looked at new type 1 diabetes diagnoses using national health registries. They discovered that type 1 diabetes was roughly 60% more likely to develop in children who had tested positive for the coronavirus.

The risk within 30 days of a Covid infection confirmed by a PCR test was examined by the researchers. Young adults were also included in a Scottish study that was presented at the European Link for the Study of Diabetes meeting. This study indicated an increased risk one month following the viral sickness, but the researchers said they discovered no association after that point.

The authors of both studies emphasised that their findings do not necessarily imply a causal link between diabetes and the coronavirus. Other potential causes were emphasised, such as delays in seeking medical attention during the epidemic, the introduction of other diseases, and alterations in way of life brought on by lockdowns.

Jamie Hartmann-Boyce, an associate professor at the Nuffield department of primary care health sciences at the University of Oxford, stated: “There are a lot of plausible reasons that Covid-19 might lead to development of type 1 diabetes, but this remains in no way proved.”
According to a paper earlier this week in the medical journal The Lancet, the number of people with type 1 diabetes, in which the pancreas fails to generate the hormone insulin, may increase from 8.4 million to 17.4 million by the year 2040.

The illness, which has no known treatment and is most frequently diagnosed in children, is thought to be caused by a combination of genetics and exposure to particular pathogens, including SARS-Cov-2 as well as a larger family of viruses known as enteroviruses. Type 2 diabetes, which is more prevalent, typically appears later in life as sedentary habits and weight increase mess with the body’s ability to manage sugar.
