COVID-19 pneumonia spreads like multiple wildfires, leaving destroyed lung tissue in its wake. ‘This effort truly represents a “moonshot” in COVID-19 research’ Scientists identify target…
A unique new study suggests that the behavior public officials are now mandating or recommending unequivocally to slow the spread of surging COVID-19 — wearing…
The spread of COVID-19 in Brazil overwhelmed the health systems in all the country’s regions, particularly in areas where they were already fragile, according to…
Method presents the immune system with several different coronaviruses at once. The SARS-CoV-2 virus that is causing the COVID-19 pandemic is just one of many…

Gut Microbiome May Influence COVID-19 Severity and Immune Response – Also Implicated in “Long COVID”
Imbalances in type and volume of bacteria may also be implicated in “long COVID.” The variety and volume of bacteria in the gut, known as…
