“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 ...
According to data from the Centers for Disease Control and Prevention, as of mid-February, around 10,000 deaths in 2024 were linked to COVID, and over 21,000 hospital admissions were due to the virus.
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 human virome in five body habitats. (A) All of the viruses detected in the five body habitats . Each virus is represented by a colored bar and labeled on the y-axis on the right side. The relative height of the bar reflects the percentage of subjects sampled at each body site in whom the virus was detected.
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 ...
To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.
"The way I look at it is the virus can still surprise us," Jha added, noting that it continues to evolve. So instead of spending time predicting the chances of a new variant, or if the virus can ...
