Cases of COVID-19, RSV and influenza have declined significantly as winter moves into spring.

Flu is rising, and COVID levels are higher than last season's peak. But COVID hospitalizations and deaths are down. Nonetheless, COVID is still the most dangerous virus circulating.

National data shows COVID-19 levels are moderate. In most of the U.S., levels of other respiratory viruses are low, although RSV is ticking up in some southeastern states.

The Food and Drug Administration has approved the first vaccine for expectant mothers to shield their babies from RSV.

The monoclonal antibody drug prevents the lung infection that puts 58,000 to 80,000 young children in the hospital each year.

At least 58,000 childern younger than 5 years old are hospitalized each year with RSV infections. A Pfizer vaccine given to pregnant people could help protect their infants from severe RSV illness.

After more than five decades of trying, the drug industry is on the verge of providing effective immunizations against the respiratory syncytial virus, which has put an estimated 90,000 U.S. infants and small children in the hospital since the start of October.

The main reason the surge is ebbing now, pandemic experts suspect, is the significant immunity many people in the U.S. have acquired from prior infections and COVID vaccinations many received.

The illness sends tens of thousands of babies to the hospital each year. If approved, the new injection would be the first broadly available prevention tool.

RSV and the flu appear to be receding in the U.S., but COVID is on the rise, new data suggests, driven by holiday gatherings and an even more transmissible omicron subvariant that has become dominant.

The Centers for Disease Control and Prevention say 56% of Georgians are fully vaccinated against COVID-19. But only a quarter got the updated variant-targeting shots this flu season.  

Pediatric cases of RSV and flu have sent families crowding into ERs, as health systems struggle with staff shortages. In Michigan, only 9 out of more than 130 hospitals have a pediatric ICU.

Experts warn winter could bring a spike in flu, RSV and COVID-19 cases. Respiratory illness rates are high and continue to overwhelm hospitals. 

Makers of products like Children's Tylenol say they're trying to keep up with big demand as RSV, flu, and COVID spread. But medical experts note that kids' fevers don't always call for medicine.

As the holiday approaches, infectious disease specialists are bracing for the possibility that big family get-togethers and travel will propel the spread of RSV, flu and COVID-19.
