Respiratory illnesses are hitting U.S. hard (12/6/22)
STAT’s Helen Branswell has this report: The U.S. is socked in with respiratory illness outbreaks, with 47 jurisdictions reporting high or very high levels of influenza-like illness activity, the CDC reported yesterday. Hospitals across the nation are struggling to cope with people sick with flu, respiratory syncytial virus (RSV), and Covid-19, CDC Director Rochelle Walensky said during a press conference called to urge people who haven’t yet done so to get a flu shot and a Covid booster and to consider wearing well-fitted masks to reduce the chances of getting infected.

Walensky said the CDC is seeing evidence of Covid infections rising after the Thanksgiving holiday. RSV levels seem to have peaked in the South and Southeast and may be leveling off in the mid-Atlantic, New England, and Midwest regions. Walensky noted that flu shot uptake is lower so far this year in some key demographics, with a 12% drop in pregnant people in comparison to last year, and a 5% drop in children under the age of 17.


Meta-analysis estimates 29% vaccine effectiveness against long COVID (12/6/22)

The authors said the results suggest that COVID-19 vaccines are more effective against persistent symptoms when given before infection, although recipients of post-infection doses also had some protection.
