Anti-sense agents suppress SARS-CoV-2 virus

Researchers in the United States have conducted a study showing that anti-sense agents called peptide-conjugated morpholino oligomers (PPMOs) have the ability to specifically and potently suppress the growth of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Confirmed early re-infection with SARS-CoV-2

As scientists strive to develop commercially viable and effective antivirals and vaccines to counter the growing COVID-19 pandemic, there is considerable uncertainty about how long and how durable the immunity induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is. A new paper recently published in the journal Clinical Infectious Disease in September 2020 reports a confirmed case of re-infection with this virus following recovery.
