The coronavirus conundrum - New subvariants of SARS-CoV-2 subvariants - COVID-19 and pregnancy - Is there a bright side to the pandemic?

Abstract

Since the late 2020's it was anticipated that the SARS-CoV-2 coronavirus would
stay with us indefinitely, but there was hope that we would be able to combat it
at some point effectively so that it would not produce the severe illness and death
that we were seeing at that time. The pandemic has continued with this coronavirus
continually modifying itself to enter the human body more easily. The Omicron
variant preferentially infects the upper respiratory tract. And some of its mutations
appear to affect parts of the spike protein that bind to ACE2. One of the latest
subvariants of the variants, BA.212.1, infects more people more rapidly, although
cases of severe infection and deaths have declined considerably. The following is
a summary of what has been known in this first quarter of the year 2022 about the
particularities of the virus, how it infects and its consequences, the protection of
vaccination, what's new about the pregnant woman and her newborn, and whether
there is any good side to the occurrence of the COVID-19 pandemic.
