France and Greece on Monday joined countries that are reimposing tighter COVID-19 restrictions to stem the surge of Delta variant infections threatening the global fight against the pandemic. The virus has killed more than four million people since first emerging in China in late 2019, and attempts to halt its […]
Russia on Wednesday reported a spike in the number of coronavirus infections as officials struggle to encourage Russians to get vaccinated. A government tally reported 10,407 new coronavirus infections across the country, the highest since March 14. Moscow, the worst-hit city in Russia, also saw a surge in new infections, […]
Japan’s third most populated region will on Tuesday ask the central government to impose a state of emergency over the coronavirus as infections rise just three months before the country hosts the Olympics. Osaka prefecture only lifted a state of emergency two months ago and restrictions are expected to be […]
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a primarily respiratory virus. It is the causative agent of the ongoing coronavirus disease 2019 (COVID-19) pandemic. In severe or critical cases, however, this virus is known to trigger rapid and severe deterioration of multiple organs, including the central nervous system. […]
A large team of researchers from the US demonstrated that pets with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) likely acquired the putative virus from humans. This suggests that human-animal infection may actually occur much more frequently than previously thought – implying that infected individuals should limit their contact […]
Amid the coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), people with comorbidities are at a higher risk of developing severe disease. In the fight against COVID-19, scientists are racing to determine effective treatments to reduce mortality among infected individuals. Now, researchers at Harvard Medical […]
The importance of cross-neutralizing antibodies to the recently emerged variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is evident in light of the fact that these variants are highly transmissible as well as being able to evade immune responses to earlier variants of this virus. A new preprint […]
A promising new study, released as a preprint on the bioRxiv* server, reports on the high neutralizing efficacy of a polyclonal swine antibody against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen responsible for the novel coronavirus disease 2019 (COVID-19). By demonstrating the ability of this antibody to […]
The effect of different neutralizing antibodies, both vaccine-elicited and from convalescent sera, suggests new variants are emerging that can evade the human immune response. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to host cells via its spike protein, which has two parts, the S1 and S2 subunits. The […]
As the coronavirus disease (COVID-19) pandemic continues, scientists race to develop or find effective treatments to stem its spread. At the same time, health experts and scientists continue to determine which existing drugs could be repurposed to treat COVID-19. Researchers at the University of Hong Kong found that Clofazimine, a […]
