Since the beginning of the COVID-19 pandemic, SARS-CoV-2 has continued to evolve, with new variants of concern (VoCs) spreading rapidly.
The scientists, in experiments described in a paper published January 6, 2022 in the journal Antioxidants, found that the compound, carnosic acid, can block the interaction between the SARS-CoV-2 outer "spike" protein and the receptor protein, ACE2, which the virus uses to gain entry to cells.
The number of confirmed COVID-19 cases worldwide now exceeds 270 million with an overall mortality rate of approximately 2%.
A new study finds that two forms of immunity - breakthrough infections following vaccination or natural infection followed by vaccination - provide roughly equal levels of enhanced immune protection.
The analysis of 204 countries and territories, published in The Lancet, reveals that AMR is now a leading cause of death worldwide, higher than HIV/AIDS or malaria.
