What other variants of concern of COVID-19 are there?
The alpha, beta, gamma and delta variants are all considered variants of concern by the WHO. The WHO classified lambda last month as a global “variant of interest” — a step below variant of concern.
How is the new mutation of COVID-19 different from the original strain?
Compared to the original strain, people infected with the new strain — called 614G — have higher viral loads in their nose and throat, though they don’t seem to get any sicker. But they are much more contagious to others.
Is South African COVID-19 variant dominant in the US?
Researchers in the United States and Canada have conducted a study showing that the South African variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – is unlikely to become the dominant strain in the US.
What is the new Delta variant of Covid?
The B.1.617.2 (delta) variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (Covid-19), has contributed to a surge in cases in India and has now been detected across the globe, including a notable increase in cases in the United Kingdom.
Which Brazilian variant of COVID-19 is more transmissible?
A recent study conducted by investigators from Brazil, the United Kingdom and the University of Copenhagen has found that the COVID-19 variant P. 1, which originated in Brazil, is more transmissible than the original virus and is able to evade immunity.

Can I still have sex during the coronavirus pandemic?

What happens if COVID-19 mutates?
Thanks to science fiction, the word “mutant” has become associated in popular culture with something that is abnormal and dangerous. Yet in reality, viruses like SARS-CoV-2, the virus that causes COVID-19, are mutating all the time and often this process does not have any impact on the risk the virus poses to humans.
How do mutations in the virus that causes COVID-19 happen?
When viruses infect you, they attach to your cells, get inside them, and make copies of their RNA, which helps them spread. If there’s a copying mistake, the RNA gets changed. Scientists call those changes mutations.
