Since the beginning of the COVID-19 pandemic, SARS-CoV-2 has mutated several times
into new strains, with an increased infectivity. Infectivity of SARS-CoV-2 strains depends on …

In this paper, for the first time, empirical formulas have been reported of the Delta and
Omicron strains of SARS-CoV-2. The empirical formula of the Delta strain entire virion was …

SARS-CoV-2 virus is the cause of COVID-19 pandemic and belongs to RNA viruses,
showing great tendency to mutate. Several dozens of mutations have been observed on the …

This paper reports, for the first time, standard Gibbs energies of binding of the BA. 1, BA. 2,
BA. 3, BA. 2.13, BA. 2.12. 1 and BA. 4 Omicron variants of SARS-CoV-2, to the Human ACE2 …

A question is often asked about what tomorrow brings. During the last 4 years of the COVID-
19 pandemic, this question was asked with every appearance of a new SARS-CoV-2 …

During the rapid worldwide spread of SARS-CoV-2, the viral genome has been undergoing
numerous mutations, especially in the spike (S) glycoprotein gene that encode a type-I …

RNA viruses exhibit a great tendency to mutate. Mutations occur in the parts of the genome
that encode the spike glycoprotein and less often in the rest of the genome. This is why …

The spread of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory
syndrome coronavirus-2 (SARS-CoV-2) has become a global health crisis. The binding …

Omicron BA. 2.75 may become the next globally dominant strain of COVID-19 in 2022. The
BA. 2.75 sub-variant has acquired more mutations (9) in spike protein and other genes of …

SARS-CoV-2, since emerging in Wuhan, China, has been a major concern because of its
high infection rate and has left more than six million infected people around the world. Many …
