“I would say the most important thing for people to know is that the virus is out there, as ... “Any new subvariant is a sign that the SARS-CoV-2 virus is still evolving; it’s still here ...
The virus is still with us, though humanity has built up immunity through vaccinations and infections. It's less deadly than it was in the pandemic's early days and it no longer tops the list of leading causes of death. But the virus is evolving, meaning scientists must track it closely. Where did the SARS-CoV-2 virus come from? We don’t know.
Viral evolution is a subfield of evolutionary biology and virology that is specifically concerned with the evolution of viruses. [ 1 ] [ 2 ] Viruses have short generation times, and many—in particular RNA viruses —have relatively high mutation rates (on the order of one point mutation or more per genome per round of replication).
The organization still had reservations, though, and cautioned that mask use by the general public was still "not yet supported by high quality or direct scientific evidence". [ 99 ] On 8 June, the WHO warned that the COVID-19 pandemic was worsening globally, with more than 136,000 cases recorded on 7 June, the highest ever in a single day.
"The virus was completely new in humans and arose from a spillover from animals and spread to pandemic levels because there was no prior exposure or protective immunity in the community," Carr ...
Experts differentiate between elimination strategies (known as "zero-COVID") that aim to completely stop the spread of the virus within the community, [166] and mitigation strategies (commonly known as "flattening the curve") that attempt to lessen the effects of the virus on society, but which still tolerate some level of transmission within ...
The SARS-CoV-2 virus still kills thousands of people around the world each month, saddles still more with chronic symptoms known as Long COVID, and continues to evolve, with the highly ...
COVID-19 is expected to circulate indefinitely, but as of 2024, experts were uncertain as to whether it was still a pandemic or had become endemic. [ 2 ] [ 3 ] Pandemics and their ends are not well-defined, and whether or not one has ended differs according to the definition used.
