New Data Suggests That 50% Of Omicron Infections In Healthy Young Men Remain Transmissible After Five Days

The study gathered PCR tests from basketball players in the National Basketball Association, aiming to elucidate the viral dynamics of Omicron, namely when viral load peaks and how long the general infection lasts.

Inhaled Remdesivir for Home Use for Covid Treatment

For a patient at high risk of severe COVID-19 related complications, newly released data shows that inhaled remdesivir offers the promise of an effective treatment for home use.

Endemic Disease Does Not Necessarily Mean Mild Disease

Many are hoping that the Omicron variant signals a transition into the endemic phase of Covid-19 pandemic. But this hope is based on the flawed logic that endemic equals mild, resulting in less severe disease and fewer deaths.

We Can’t Stop Reporting Covid Cases

Understanding infection rates in our communities is critical knowledge that keeps us safe by allowing us to modify our behavior based on risk.

Time to Expand Vaccination to Infants and Toddlers and Boosters for Children

Innate immune protection against the COVID-19 virus largely spared young children from contracting previous variants. Omicron, however, has unique adaptations that penetrate natural immunity, leading to record rates of infection and hospitalization amo…

Omicron: Less Virulent But Still Dangerous

A recent study found that Omicron is less virulent in mouse and hamster models.

The Case For Third And Fourth Booster Shots

A third dose of the mRNA vaccines is one tool that can be deployed swiftly to save lives and hospital beds.

The Challenges of Treating COVID-19: Lessons from Gilead’s Remdesivir

As the first and only FDA approved antiviral treatment for COVID-19, Gilead’s remdesivir has been shown to prevent individuals at high risk of severe disease from being hospitalized. However, inherent eligibility and accessibility restrictions reduce i…

SARS-CoV-2 Protein Orf6 Suppresses MHC-I And Recognition By Cytotoxic T Cells

By coding for viral proteins that block immune detection of microbial threats, SARS-CoV-2 is able to establish infection and proliferate to high titers before the immune system can react. One of these proteins is open reading frame 6, or Orf6.

New Potential Covid Virus Variants Of Concern

Scientists and epidemiologists around the world are alert to the possibility that yet another dangerous variant may arise. This is the context to understand the interest in a recent report of a new variant, B.1.640.2, in France.
