SARS-CoV-2, the virus that causes COVID-19, is a single-stranded RNA virus. These viruses are notoriously sloppy replicators. They areprone to developing random mutationsas they replicate in a population, meaning SARS-CoV-2 mutations happen pretty regularly, and their severity depends on where ...
As the vaccines for COVID-19 continue to roll out and tens of millions more doses get into tens of millions more arms, I’m coming to the reluctant conclusion that I could, if I so desired, do nothing but blog about the antivaccine misinformation about these p...
However, neither nonhuman primate model led to respiratory failure or mortality, and thus further research will be required to develop a nonhuman primate model of severe COVID-19 disease. SARS-CoV-2 infection in rhesus macaques led to humoral and cellular immune responses and provided protection ...
Testmore than once, especially if your symptoms are mild. The at-home rapid tests may not detect COVID infection in the first couple of days, according to the FDA, which recommends using "multiple tests over a certain time period, such as two to three days." With all three viruses, ...
By sheer luck, certain existing PCR tests can detect the British variant. Fontanet therefore advocated "extremely aggressive surveillance" through widespread testing. "We need to be even more vigilant in our prevention measures to slow the spread of COVID-19 by wearing masks, staying at least si...
Genomic conservation means Thermo Fisher’s assays are designed to look at areas of the viral genome that are less likely to mutate even as the virus evolves. Specificity means the assays are designed to only detect regions that are unique to the SARS-CoV-2 virus, not other viruses or micro...
And we saw a huge drop-off in COVID-19 cases, as well as flu, RSV and other illnesses. That's a reminder "that there are things that you could do that really minimize your exposure to viruses," Esper says. Limit exposure to people who are sick. Keep your distance from people who ...
Market researchers have noticed that the public has lately been gravitating toward unaccustomed smells. “We knew because of Covid, there were going to be shifts in terms of consumer behavior,” says Fabien Craignou, who studies finicky global perfume markets for the Swiss fragrance company Firmeni...
But I do know how to win against the viruses. And I have been winning. Time will prove me right. I am ahead of the time after all. Just like my analysis on Covid a year ago. No one believed me. But time proved me right , didn’t it ?Time will prove me right again. ...
Hunting for new viruses has become more difficult during an actual pandemic, but it has never been more important. This year, Covid-19 has brought some of the most powerful countries in the world to their knees. Like most other novel human viruses, Sars-Cov-2, which causes Covid-19, is...
