The six strains of SARS-CoV-2:

"The SARS-CoV-2 coronavirus is presumably already optimized to affect human beings, and this explains its low evolutionary change," explains Federico Giorgi, a researcher at Unibo and coordinator of the study. "This means that the treatments we are developing, including a vaccine, might be effective against all the virus strains."

Currently, there are six strains of coronavirus. The original one is the L strain, that appeared in Wuhan in December 2019. Its first mutation—the S strain—appeared at the beginning of 2020, while, since mid-January 2020, we have had strains V and G. To date strain G is the most widespread: it mutated into strains GR and GH at the end of February 2020.

Globally, strains G, GH and GR are constantly increasing. Strain S can be found in some restricted areas in the U.S. and Spain. The L and V strains are gradually disappearing.

    Don't be wilfully stupid. When antibiotics kill off your gut bacteria, you wilfully infect yourself with new bacteria. In extreme cases hospitals have a treatment room reserved for fecal transplants. Harvard's definition is not a one size fits all. BTW, even beneficial bacteria can turn rogue - like the flesh-eating disease - and attack the host. Log in to continue or fuck off.

    Don't be willfully stupid. We were talking about bacteriophages and the bacteria hosts.
