As Covid-19 's Delta variant continues to spread worldwide, doctors say it can cause more hospitalisations than the original strain
Research in Canada, Singapore and Scotland shows people, mainly those who are unvaccinated, infected with Delta variant are more likely to be hospitalised than patients earlier during the pandemic.
But the experts said more work is needed to compare outcomes among larger numbers of individuals in epidemiologic studies to sort out whether one variant causes more severe disease than another."It's difficult to pin down increase in severity and population bias," said Lawrence Young, a virologist at the UK's Warwick Medical School.
In addition, it is likely that the extraordinary rate of Delta transmission is also contributing to a greater number of severe cases arriving at hospitals, the experts said.Delta is as contagious as chickenpox and far more contagious than the common cold or flu, according to the CDC report.
Shane Crotty, a virologist at the La Jolla Institute for Immunology in San Diego, said the clearest indication that the variant may cause more severe disease comes from the Scotland study, which found that Delta roughly doubled the risk of hospitalisation compared to an earlier version. headtopics.com
The majority of hospitalisations and deaths from coronavirus in the United States are occurring in people who have not been vaccinated. But there is evidence that the shots are less effective in people with compromised immune systems, including the elderly.
For vaccinated, otherwise healthy individuals, the odds are that if they contract Covid-19 they will only experience asymptomatic or mild disease, said Dr.Gregory Poland, infectious disease expert at the Mayo Clinic."But they can pass it on to family members and others who may not be so lucky," Poland said. "We have to be vaccinated and masked or we will, for the fourth time now, endure another surge and out of that will come worse variants."

"This is like a wildfire, this is not a smouldering campfire. It is full-on flames right now," said Dr. Michelle Barron, senior medical director of infection prevention and control at Colorado's UCHealth.Research from China suggesting that the Delta variant replicates much faster and generates 1,000 times more virus in the body compared to the original strain highlights the biggest danger of this new wave, Barron said. headtopics.com
"It is hard to tell if they are more sick because of the Delta variant or if they would have been more sick anyway," she said.Other doctors said patients infected with Delta appear to become ill more quickly, and in some cases with more severe symptoms, than those they treated earlier in the pandemic.
"We are seeing more patients requiring oxygen sooner," said Dr. Benjamin Barlow, chief medical officer at American Family Care, a 28-state chain of urgent care clinics.At his clinic in Birmingham, Alabama, Barlow said that around 20 percent of patients are testing positive for Covid-19, compared with 2-3 percent a few weeks ago. Patients are assessed at that time for potential hospital admission and oxygen support.
David Montefiori, director of the Laboratory for AIDS Vaccine Research and Development at Duke University Medical Center, said the Delta variant is more infectious and leads to faster onset of illness - particularly for the unvaccinated."Frankly there's a severity that comes from this variant that is a little more severe," Montefiori said on a webcast last week. "It's not just easier to transmit, it makes you sicker."Read more: TRT World »

Delta spreads 'like wildfire' as doctors study whether it makes patients sickerWith a new wave of COVID-19 infections fueled by the Delta variant striking countries worldwide, disease experts are scrambling to learn whether the latest version of coronavirus is making people - mainly the unvaccinated - sicker than before. The U.S. Centers for Disease Control and Prevention warned that Delta, first identified in India and now dominant worldwide, is 'likely more severe' than earlier versions of the virus, according to an internal report made public on Friday. The agency cited research in Canada, Singapore and Scotland showing that people infected with the Delta variant were more likely to be hospitalized than patients earlier in the pandemic. VaxUPBitches! DON'T be an AntiScienceAHole!! It's also like the chickenpox, as that once you get it, you're basically immune to it afterwards, unlike dangerous experimental vaccines that have been actually causing more harm than good. But no, you won't report on that will ya! Hacks!

Delta Variant Spreads to Indonesia’s Remote, Vulnerable IslandsFor 18 months, a town in a remote, heavily forested part of eastern Borneo island had avoided the worst of Indonesia’s Covid-19 pandemic.
