У коронавируса- все отлично.
Работа от англичан, по эволюционной генетике, которая показывает что коронавирусу с нами хорошо, он прекрасно размножается, очень выгодно мутирует, приобретая все лучшие способности, и пока что каждая новая коронавирусная волна (от победителей эволюционного отбора, альфы, дельты итп) из-за приобретенных вирусом преимуществ (ну и не без того, что надежный иммунитет, предотвращающий заражение- не вырабатывается) охватывает нашу популяцию быстрее и шире.
Конечно данные по Великобритании- в Китае, где пресекают жестко, наверное, местная эволюция не такая быстрая, разнообразная и успешная. Но вов сем мире- дело происходит примерно как в ВБ, потому борьба за существование предстоит долгая и с переменным успехом.
The Office for National Statistics COVID-19 Infection Survey is a large household-based surveillance study based in the United Kingdom. Here, we report on the epidemiological and evolutionary dynamics of SARS-CoV-2 determined by analysing sequenced samples collected up until 13th November 2021. We observed four distinct sweeps or partial-sweeps, by lineages B.1.177, B.1.1.7/Alpha, B.1.617.2/Delta, and finally AY.4.2, a sublineage of B.1.617.2, with each sweeping lineage having a distinct growth advantage compared to their predecessors. Evolution was characterised by steady rates of evolution and increasing diversity within lineages, but with step increases in divergence associated with each sweeping major lineage, leading to a faster overall rate of evolution and fluctuating levels of diversity. These observations highlight the value of viral sequencing integrated into community surveillance studies to monitor the viral epidemiology and evolution of SARS-CoV-2, and potentially other pathogens, particularly as routine PCR testing is phased out or in settings where large-scale sequencing is not feasible.
