Benjamin Meyer, a virologist at the University of Geneva in Switzerland, says he too was stunned by Grad’s results. “Naturally, you’d think that higher transmissibility must cause a higher viral load,” he says.
Meyer and his colleagues took the study a step farther: rather than measuring only viral RNA, they also measured the number of infectious virus particles on swabs collected from a separate group of almost 150 infected people . This more stringent method found no significant difference between the viral loads of vaccinated individuals infected with Omicron and those infected with Delta.The findings have implications for government policies on isolation after infection. Meyer’s team examined samples from people who had beenThey found that about half of the samples still held infectious virus five days after the individuals tested positive.
Such results are concerning, Grad says, because guidelines published by the US Centers for Disease Control and Prevention allow people infected with the virus to end their isolation five days after either testing positive or experiencing their first symptoms. The guidelines specify that people who have exited isolation must continue to
around others for five more days, but do not require a negative COVID-19 test to end isolation. The CDC did not respond toOmicron has made public-health decisions all the more difficult, Grad says. He and his colleagues also found more variability in viral load in individuals infected with Omicron than in people infected with Delta. “That means there’s no clear ‘one size fits all’ approach,” he says.
La elevada transmisibilidad de ómicron puede ser como dicen los investigadores por evasión del sistema inmune y yo pienso qye puede ser por su elevada velocidad de infección celular y replicación ( utiliza una vía de entrada por endosomas independiente de tmprss )

Why you should still try to avoid catching omicronA fast-spreading omicron variant that causes milder illness compared with previous versions of the coronavirus has fueled the view that COVID-19 poses less of a risk than in the past. It's time to let these things spread and get onto the endemic phase of this crap. These spike vaccines are not the way out of this mess. Let the body do it's thing and get a better and complete picture of this virus and how to fight it. We the people are tired. We've listened and done what you've said to do. Vaccines 3 times, masked all the time, isolated, closed businesses. Still got it. Sick as a dog. Don't care what the 'experts say anymore!' Stop it. We're over your fear propaganda. COVID is Endemic and your manipulative ways aren't going to save Biden and the Dems come 2022 & 2024. It's over.

China Believes That Omicron Variant Found Its Way to the Country via MailEven as the world battles Omicron, daily cases in China have remained low. Authorities want residents to avoid international mail to curb Omicron spread. Mail, hamsters ! Hi, I am a structural engineer from Iran who have many ideas. I have summarized some of my ideas on my twitter(I suggest look at the idea of generating electricity by gravity). I want to work with companies and investors. Do you want to cooperate? What goes around, comes around !!

It's Time to Upgrade Your Mask, Experts Say. Here's WhyWith the rapid spread of Omicron, many countries are rethinking their COVID mask advice for the community. And please, wear it correctly, bend those tabs to fit well over the bridge of your nose. Wearing a mask has 0 impact in virus protection. It passes through with no issues...at least through the ones advertised since the start of pandemic I’ve bought four different N95 masks and none fit, they are too small. Anyone know where I can buy a larger N95 mask?
