‘Various strains’ of Covid-19 detected in the UAE Photo: Reuters Dr Nawal noted that mutations are common in SARS-CoV-2 — an RNA virus. While a “limited number” of the UK strain of Covid-19 was found in the UAE, a top health official said several variants are already detected in the country. “Strains are common and, yes, various strains have been detected — but with these small changes, the treatment, management and vaccination method remain the same,” Dr Nawal Al Kaabi, Chairpe...

A biologist who studies the evolution of diseases explains what's different about the two new virus strains that have been found recently, and what that means for vaccine effectiveness.

Image-based deep learning haplotype-guided study maps the global adaptation of SARS-CoV-2 To date, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), has caused more than 93.21 million infections worldwide. As it spreads through different populations, it undergoes adaptations that sometimes affect its transmissibility and other biological characteristics. An interesting preprint on the bioRxiv* server describes the u...

Concern develops over Brazilian SARS-CoV-2 variant The variant, thought to have originated in Brazil, is affecting travel to South America as effort is made to prevent its spread. Meanwhile, areas of Brazil are experiencing surging numbers of COVID-19 cases and oxygen supplies are running out.

A recent study conducted by a team of international scientists has revealed that the infectivity and pathogenicity of SARS-CoV-2 strongly depend on the genetic background of both the virus and the host.

"The mutations in the Columbus strain are likely to make the virus more infectious, making it easier for the virus to pass from person to person," Ohio State University said in a statement.

A press release by the Ohio State University, Wexner Medical Center says that their  Scientists have detected a new variant of the SARS-Cov-2

China finally lets WHO into Wuhan to probe COVID-19 origins By Ramy Inocencio WHO team in China probing COVID-19s origins Wuhan, China — More than a year after the worlds first known coronavirus cases appeared here, a World Health Organization team of experts finally landed in Wuhan on Thursday to try to trace the origin of the deadly virus. But the highly-anticipated visit is now being met with international skepticism because of how long the Chinese government waited ...

The WHO is holding an emergency meeting to discuss the new variants of the coronavirus. There are concerns that they may be much more infectious than the first strain that emerged in China, and could potentially render some vaccines less effective.
