Evidence suggests that SARS-CoV-2 suppresses the immune response in the first few days following infection. The process can be likened to an expert act of burglary.

A new study from UC San Diego demonstrates that wastewater surveillance can detect Covid-19 in a single infected, asymptomatic person living or working in a multi-unit dwelling such as a university campus building.

A complex genome and replication strategy offers many new opportunities to develop drugs that prevent and treat Covid-19 infections.

SARS-CoV-2 has evolved mechanisms that allow it to dodge innate immunity, many of which kick in early, allowing the virus enough time to enter, proliferate, and exit before the immune system can respond.

The Covid-19 virus is a master at evading both the defenses of an infected cell and the entire immune system. This has myriad implications for drugs, vaccines, and other aspects of our pandemic response.

Despite not having the official label of Variant of Interest or Concern, it should be noted that B.1.621 has certain characteristics that suggest it may be worth watching, as it could become a variant of interest or concern in the near future.

Cases are occurring in both vaccinated and unvaccinated populations, yet with one of the highest vaccination rates in the world, Israel’s experience confirms that no single modality will control Covid-19 alone, as the virus continues to evolve and muta…

Throughout the pandemic we have told ourselves stories that were convenient truths until proven false—mythologizing a virus when it needed rigorous, evidence-based demystifying. Here’s where we went wrong and how we can fix it.

In lieu of rigorous public health controls, there are practical considerations we can make at the individual level to protect ourselves and the people around us.

An estimated 1.5 million children globally have lost a caregiver or parent due to Covid-19. We must develop programs to support these children emotionally and financially.
