A mutant coronavirus has emerged, even more contagious than the original, study says
Scientists have identified a new strain of the coronavirus that has become dominant worldwide and appears to be more contagious than the versions that spread in the early days of the COVID-19 pandemic, according to a new study led by scientists at Los Alamos National Laboratory.
The new strain appeared in February in Europe, migrated quickly to the East Coast of the United States and has been the dominant strain across the world since mid-March, the scientists wrote.
In addition to spreading faster, it may make people vulnerable to a second infection after a first bout with the disease, the report warned.
“We are looking to identify the mutation,” he said, noting that his hospital has had only a few deaths out of the hundreds of cases it has treated, which is “quite a different story than we are hearing from New York."
People infected with the mutated strain appear to have higher viral loads. But the study's authors from the University of Sheffield found that among a local sample of 447 patients, hospitalization rates were about the same for people infected with either virus version.
“The rate at which this virus is mutating or evolving is not unexpected; it’s exactly what we would expect for a virus like this,” says Nathan Grubaugh, a virologist at the Yale School of Public Health in New Haven, Connecticut. “All viruses continuously evolve and there shouldn’t be anything alarming about the process in general.”
However, the bulk of the mutations that appear as a virus spreads are either harmful to the virus itself (meaning it is less likely to survive or replicate) or don’t change how it functions. Additionally, the two characteristics that are of most concern right now—how contagious the virus is and how harmful it is to its hosts—are controlled by multiple genes, Grubaugh says. Changing these characteristics is a complicated process, and not often the work of a single mutation. So the odds of the virus mutating in such a way that it actually becomes more lethal or contagious over the timescale of weeks, months, or even a couple years aren’t very high.

There are no "strains" its all fear mongering....there is one single Pleomorphic Bacteria.
Your uneducated and unscientific opinion is just as bad as the fear mongering.

It's called "marketing"...give a person to read "See them now!"...which makes you click and flip so you can't help but see the ads...
Brilliant actually, and time-tested...you want more(especially slideshows)...

It's about more than just ad revenue. The headline would be all they need if that was the case and the real info wouldn't always be buried at the bottom.
Also, ad blocker helps with that

Viruses are not bacteria.
