Why does COVID-19 make you sneeze?
Science Viral protein stimulates nerves in respiratory passages, could be target for treatment SARS-CoV-2 has many ways of making people miserable, including by causing them to sneeze. Now, researchers have discovered the basis for this nose-tickling effect. One of the virus’ proteins stimulates neurons in respiratory passages, triggering the sneeze reflex. The results could spawn […]

Paxlovid helps prevent severe illness from COVID. Why don’t more people take it?
Yahoo News With the current COVID-19 death toll in the U.S. at more than 1.1 million and new evidence that COVID infections can damage the brain, heart and lungs, it’s clear that the disease is more than “just a bad cold.” Paxlovid, which is a combination of two drugs (nirmatrelvir and ritonavir), can lower the risk of severe symptoms […]

A big shift in collecting COVID data — from case counts to monitoring poop
NPR Earlier this year, the CDC stopped collecting data on new infections (as in positive tests) – relying instead on COVID hospitalizations, deaths and, increasingly, on wastewater surveillance – a network set up during the pandemic to regularly test sewage samples from around the country. The surveillance network has expanded beyond COVID to track flu, RSV, norovirus and other health threats that are […]

Scientists Identify Interferon-gamma as Potential SARS-CoV-2 Antiviral
NIH Conditioning the lungs with interferon-gamma, a natural immune system protein (cytokine) best known for fighting bacterial infections, appears to be a strong antiviral for SARS-CoV-2, according to National Institutes of Health scientists and colleagues. Their new study, published in Nature Communications, shows in two different mouse models that when a bacterial infection triggers the release […]

New blood testing method advances disease detection
Arizona State University Researchers at the Arizona State University Biodesign Institute have made an impressive leap in disease detection, with a novel screening method that can look at hundreds of disease markers and evaluate thousands of samples simultaneously, delivering most results in 24 hours. Unlike conventional blood tests, the new platform, called Multiplexed In-Solution Protein […]

Pre-Existing SARS-CoV-2 T Cells Predicted to Recognize New Pirola Variant
Genetic Engineering and Biotechnology News SARS-CoV-2 variants continue to evolve (even if they are no longer making headlines.) In August, researchers detected a new SARS-CoV-2 “variant of concern” in patients, first in Israel and Denmark. Over the past few months, this variant, BA.2.86 or “Pirola,” has made its way around the globe. The Pirola variant […]

Replication-Competent Virus Detected in Blood of a Fatal COVID-19 Case
Annals of Internal Medicine Background: SARS-CoV-2 infects respiratory tissues, and in some cases, replication-competent virus has been detected in extrapulmonary tissues, including brain (1). Viremic spread is suspected, and detection of viral RNA in blood is frequently reported (2). However, recovery of replication-competent virus from blood has not been previously demonstrated (3, 4). Objective: To confirm viremia in […]
