However, there is strong evidence that two of the variants -- those that were first identified in the U.K. and South Africa -- are more transmissible. Now, scientists are racing to understand exactly what it is about these two variants that makes them easier to jump from person to person, and whether we should be worried that other variants might do the same.Pedestrians wearing facemasks walk past a prevent the spread of Covid-19 banner in Los Angeles, Jan. 19, 2020.
With more virus in the respiratory droplets, it could be easier to get an infection if a droplet lands in your eyes, mouth or nose.In a related theory, scientists are investigating whether the new variant might somehow lengthen the number of days an infected person is contagious.A pedestrian passes by a notice of social distancing in New York, Jan. 9, 2021.
That could cause others to be infected, because you might not be quarantining when you should be and therefore exposing others unknowingly.Yet another idea is that the virus might have evolved to be sturdier and better able to withstand the harsh environment outside the human body. Many scientists feel confident about this theory, because the mutations they found in the U.K. and South African variants are in those little"spikes" on the outside of the virus. The virus uses those spikes to bind to a specific site on our cells called the ACE2 receptor.Most of the mutations “have predominantly been at the interface where the virus meets the cell receptor,” Kuhn said.
There are still many questions regarding the COVID-19 variants and what they mean in the course of the pandemic, but scientists are working every day to learn about them. Each time a new variant is discovered, researchers will need to characterize the variant to understand what the mutations do and how they could alter the course of the pandemic.

The only way to stop the spread. Listen to Fauci
I owe you an apology to ever doubt your sincerity and professionalism. It’s was just like a dream to me when I received my first payment. After my second payment it became a reality now after several payments it has become a way of life. marksust7
Cause its the flu.
The British Covid B117 and the African variety are highly contagious.
Its a virus! Thats what they do.
Fear to be obedient. Ppl need to get educated up on...we are surrounding by viruses, bacteria and fungi. Since beginning of time.
It bothers me when news outlets ascribe intentionality to viruses, especially since we've been attentive for over a year. The article describes the Covid-19 virus mutating to prolong it's infectious period. That's a stupid thing to say. It makes naive readers more foolish.
Why, is this variant smaller in diameter than the one before it or is it just first time exposure with no buildup resistance?
Have they really proven that viruses are contagious?
Plan is to not read anything with the word variant in it for a while. I don’t even deviate from my course on a walk so the word variant won’t pop into my head
95% only bad news(
This is the article “there are many theories”, “could be”, “may be” the same as there could be a “pandemic” or there may be a COVID virus. Who really knows the REAL truth? The government will declare a situation to be for their “own”reasons unknown to the people
I thought masks worked?
It’s just more fear incitement.
Bullshit c19 has been mostly poor testing to tale down trump.
Theory 5 - it’s just cold and flu season. That’s it.
Thanks for the report & posting this! (yitt)
It is very disturbing that there are people who still believe that Covid-19 is hoax. I wish they would start realizing the Covid-19 IS NOT a hoax and start listening to President Biden, Scientists/Experts. Covid-19 got out of hand because Trump didn’t do anything.
COVID19
Theorize? 😂😂
I know this is a random place to promote but I've been battling cancer for the last 4 years and now it's spreading. I'm raising money to help fight my Cancer as my condition worsens. My mom's a single parent no job or financial support. Plz Anything helps!
You guys are really trying by all means to instill fear,we already have fear, it's enough,we can't take more 😭
Simple it's cold and flu season, you can't fool mother nature

If this was actually a real virus it would be airborne
1. “It” can’t. That’s all.
In that 75% of human infectious disease is somehow linked to our consumption of fellow animals, maybe you could examine that at some point in the interest of pandemic prevention. Just a thought.
This is a little off topic but can anyone tell what type of mask is the one in the thumbnail?
Maybe because our blessed masks get touched over and over all day long and then go right up against our mouths but what do I know
as a news source you should be giving us facts not so called theories.
