A coronavirus variant first reported in Britain is believed to be potentially 50 percent more transmissible and has spread to over 50 countries. Here’s how it was born.https://t.co/UQ5ZhDLGWK
A number of researchers suspect that B.1.1.7 gained many of its mutations within a single person. People with weakened immune systems can remain infected with replicating coronaviruses for several months, allowing the virus to accumulate many extra mutations.
When these patients are treated with convalescent plasma, which contains coronavirus antibodies, natural selection may favor viruses with mutations that let them escape the attack. Once the B.1.1.7 lineage evolved its battery of mutations, it may have been able to spread faster from person to person.
B.1.1.7 is estimated to be roughly 50 percent more transmissible than other variants. Federal health officials warn that it may become the dominant variant in the United States by March. It is no more deadly than other forms of the coronavirus. But because it can cause so many more infections, it may lead to many more deaths.
B.1.1.7 has been detected in at least 14 states, but the United States has no national surveillance program for determining the full extent of its spread.
“I want to know,” one twin said, “why did she have Covid worse than me?”
Kelly and Kimberly Standard both had the coronavirus last spring. Kelly was hospitalized for less than a week. Kimberly spent almost a month in critical condition. https://t.co/12cdIe69ia
Some researchers have also floated the idea that the amount of coronavirus a person takes in may have an impact on the severity of disease, a trend that has been documented with other infections.
“It’s the difference between having your immune system being actually able to squash the infection, or having a much harder time fighting it if all your cells become infected at the same time,” said Juliet Morrison, a virologist at the University of California, Riverside.
Michael Russell, 29, says he wonders if he sniffed up more of the virus than his twin brother, Steven, did this summer, in the days after they gathered with their family for the Fourth of July.
Both brothers began experiencing symptoms shortly after the celebrations ended, around the time Steven headed back to his home in Arlington, Va. The virus saddled Steven with a scratchy throat and a headache — a “light, cold-like” illness, he said.
A few days later, Michael, who was living at home with his parents, came down with much more severe symptoms: a sore throat, chills, shortness of breath and fatigue that relegated him to his bed for an entire day. About two weeks passed before he could smell or taste the cinnamon-dusted popcorn he regularly snacks on.
The twins’ parents came down with bad Covid symptoms as well, so Michael had to isolate with two other infected adults. Hunkering together in the same house may have exposed him to a larger dose of the virus, the brothers said. But, they added, that’s just a guess.
For some twin pairs, there are no obvious explanations for their differing disease course. Marena and Vivian Herr, 17-year-old identical twins in Jackson Hole, Wyo., have spent their entire lives near each other, bonding over their tastes for In-N-Out Burger and Taylor Swift.
“We share drinks, we hang out in each other’s rooms, we have the same friends,” Vivian said. But she and her sister never seem to catch the same sicknesses.
When the sisters both fell ill from Covid the week after attending a Halloween party, their symptoms forked: Marena lost her sense of taste and smell, neither of which have returned in the two months since, while Vivian battled a debilitating flulike illness.
Warp Speed did real good. But I don't think it's sunk in just how little the Trump admin did to prepare for vaccine distribution. They acted like a vaccine would solve the problem for them. But that's not how this works. And now we've wasted so much time. https://t.co/6woZ0LkUc2
All infections of the new COVID-19 variants in Germany have been related to travel.
There have been 16 reported cases of the coronavirus variant that was first detected in Britain, and four of the variant from South Africa.https://t.co/NN8Z4w7Rf1
BREAKING: The UK now has the highest covid death rate in the world. A horrifying, heart-breaking, appalling fact that shames our country & our Govt. pic.twitter.com/URqGbu0ate
^ Czech Republic currently # 2. Sweden way up there. Germany doing no better than the U.S. France and Austria interestingly way down there with Israel.
this other graphic from the Independent is pretty damn scary (BTW the article is free access) and article notes that hospitalizations as well as deaths are higher than the first peak:
imo “everyone should wear a mask” is still a good rule just for enforceability reasons when out and about, but we should emphasize to people that if you get the shots all kinds of socializing are back on the table https://t.co/M6e4bcHAjI
Somehow in epidemiology “we haven’t done a double-blind clinical trial” = “no evidence” but in pediatrics everything is “here’s an observational study with incredibly obvious confounds we made no effort to control for whatsoever.”
thread on NYTimes article; not real good news but so far “is not something that we should be horribly freaked out about.”
REINFECTION & VACCINE SENSITIVITY—the concern is now growing very very real. This piece highlights the big S Africa CDC report I shared earlier, where antibodies from previously infected don’t recognize the #B1351 variant in 48% of patients. #COVID19https://t.co/01WY1I6uYPpic.twitter.com/MrNayZdGU2

CRUCIAL GREAT NEWS:we're back in the W.H.O. and Fauci will lead the U.S. delegation!!!
Somebody's got to bully pulpit and lead this thing worldwide or we are doomed to keep passing variants country to country!
On his first day in office, President Biden retracted a decision by the Trump administration to withdraw from the World Health Organization. Dr. Anthony Fauci will lead the U.S. delegation.https://t.co/MkWy6kHUgL

Sounds to me like we may have to eventually get new, updated vaccines all the time like we do with flu?
