The coronavirus that causes Covid-19 may spread through the lungs by turning previously resistant cells into targets for infection, a finding that helps explain the widespread inflammation and organ damage seen in severe cases and points to a potential new treatment. (Gale, 4/13)

The US measles case count grew by 43 cases this past week, reaching 1,714, the Centers for Disease Control and Prevention (CDC) said today in its weekly update. The increase is much smaller than the 96-case jump last week, and more than half of the new cases are in Utah. (Wappes, 4/10)

Measles is best known for causing a full-body rash with red spots. But those spots aren’t the only symptom. Early measles symptoms can resemble the flu, and infected people are contagious for four days before the tell-tale rash appears, experts say. People with measles are also contagious for four days after the rash begins.

Even as the US respiratory illness season continues to ebb, it remains deadly, with the Centers for Disease Control and Prevention (CDC) documenting 12 more pediatric deaths in its FluView update today. So far this season, 139 children have died from the virus, and about 85% with a known vaccination status were unvaccinated. While the CDC has classified this flu season as moderate for adults, it’s been high-severity for children.
