Scientist Semenov: coronaviruses have a high potential to break through interspecific barriers 
Alexander Semyonov spoke about groups of coronaviruses that are ready to break through to people in an interview with Izvestia.
As the scientist explained, coronaviruses have an extremely high potential for breaking through interspecific barriers, so they cannot “surprise” people in the future. In addition, there are several more groups of viruses that stand on the border of the interspecies barrier and are ready to break through it. “We must understand that this may happen in the foreseeable future, and be ready for it,” he warned.
Semenov also recalled that the pathogen SARS-CoV-2 has become the third coronavirus in the past 20 years. which successfully broke into the human population. “This means that somewhere there may be a fourth and a fifth,” he said. Before SARS-CoV-2, SARS-CoV-1, which caused SARS, and the Middle East Respiratory Syndrome Virus (MERS) were able to penetrate people.
In the same conversation, Alexander Semenov said that omicron- the strain descends more quickly into the lungs, causing pneumonia. When infected with the previous variants of the coronavirus in humans, it took up to 10-11 days from the moment of infection to pneumonia. However, this period has now been reduced to 3-5 days.
