Study reveals why SARS-CoV-2 is more infectious than SARS-CoV-1

Coronaviruses such as the severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 are enveloped positive-sense RNA viruses that are a huge threat to public health globally. They can be transmitted from animals to humans and can cause many diseases ranging from the common cold to severe respiratory illnesses. Structural similarities between SARS-CoV and SARS-CoV-2 viral …

Comparison of recombinant SARS-CoV-2 receptor binding domain produced in mammalian, insect, and bacterial cells

Comparison of recombinant SARS-CoV-2 receptor binding domain produced in mammalian, insect, and bacterial cells

The spike (S) protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a critical role in receptor recognition and host-cell entry. Thus, major efforts to characterize and reproduce this protein in its truest form have been underway since the inception of the coronavirus disease 2019 (COVID-19) pandemic to support the development of adequate …

Study reveals how saline solution can inhibit replication of SARS-CoV-2

Study reveals how saline solution can inhibit replication of SARS-CoV-2

The use of a hypertonic solution of sodium chloride at 1.1% reduced viral replication by 88% in tests involving infected lung cells conducted by researchers at the University of São Paulo. If found efficacious in clinical trials, the strategy could contribute to the development of novel prophylactic interventions and therapies for COVID-19. Credit: Researchers’ archive …

COVID-19 vaccine effectiveness against SARS-CoV-2 variants

A commentary published in the journal Cell summarizes international data on vaccine effectiveness against new severe acute respiratory coronavirus 2 (SARS-CoV-2) variants. Evidence shows that the currently approved vaccines continue to be effective in preventing severe and symptomatic illness — even with the widely circulating Delta variant. SARS-CoV-2 has mutated many times in the pandemic. …

What impact has SARS-CoV-2 variant B.1.1.519 had on Mexico City?

Coronavirus disease 2019 (COVID-19) has become one of the most concerning diseases globally since its initial outbreak. It is of great importance that monitoring new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants is ongoing because mutations could change viral biological properties. Viral genome alterations could alter neutralization efficiency resulting from naturally acquired immunity, and …

Asymptomatic SARS-CoV-2 infections vary with age and geographical location

A distinguishing feature of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) compared to severe acute respiratory syndrome (SARS) is that it is spread not only via symptomatic people but also asymptomatic and pre-symptomatic people. Asymptomatic cases are becoming of increasing concern due to the potential of people unknowingly causing local outbreaks within their communities. In …
