Coronavirus infections in Asia passed 100 million on March 30, according to a Reuters tally, as the region records a resurgence in cases dominated by the BA.2 Omicron sub-variant.

The U.S. national public health agency said on March 29 that the BA.2 sub-variant of Omicron was estimated to account for more than half the coronavirus variants in the country.

A sub-variant of the highly transmissible Omicron version of coronavirus known as BA.2 is now dominant worldwide, prompting surges in many countries in Europe and Asia and raising concern over the potential for a new wave in the United States.

The U.S. health regulator said on March 25 the current authorized dose of GlaxoSmithKline and Vir Biotechnology’s COVID-19 antibody therapy is unlikely to be effective against the Omicron BA.2 variant.

A year after infection with the coronavirus – when antibodies in the blood are barely detectable – the immune system continues to “remember” the virus and should respond to some extent upon re-encountering it, a study from China suggests. According to new research, women who were pregnant during the recent Omicron surge had more than eight times the rate of COVID-19 diagnoses, but lower odds of severe illness compared with pregnant women diagnosed earlier in the pandemic.

Shanghai’s bespoke approach to tackling coronavirus outbreaks is coming under strain as new cases rise in the Chinese metropolis, with authorities reluctant to impose a comprehensive lockdown as other cities have done.

Top U.S. infectious disease official Dr. Anthony Fauci said on March 22 he would not be surprised to see an increase in COVID-19 cases in the United States, but he does not expect a major surge.

The BA.2 Omicron sub-variant of the coronavirus was responsible for over a third of all COVID-19 cases in the United States in the week ending March 19, according to an estimate from the U.S. Centers for Disease Control and Prevention (CDC) on March 22.

Adamis Pharmaceuticals Corporation announced that in studies conducted at Galveston National Laboratory (GNL), University of Texas Medical Branch (UTMB) at Galveston, hamsters challenged with high levels of the Omicron variant of the SARS-CoV-2 virus resulted in significant decrease of inflammation in the lungs of animals treated with Tempol compared to controls.
