While COVID is still out there, it's the viruses that have long been circulating that sent so many kids to the hospital this cold and flu season. Things like RSV and the flu. So what made this year so unusual?
It has been a tough cold and flu season. COVID-19 is still a concern, but it's the viruses that have always been circulating that are causing serious illness and filling up hospitals. Things like the flu and RSV. So, why has this season been so bad? KSAT Explains explores why.– If it feels like you’ve been playing a “guess the virus” for months now, it’s not just you.
During the pandemic, babies who would normally be exposed to RSV and build up some immunity didn’t get that exposure because of the precautions we needed to take for COVID.“Last year it wasn’t bad at all for the flu,” Alsip said. “And then the year before that it was almost nonexistent.”Both the flu and RSV are aerosolized viruses, meaning they spread by someone coughing, breathing out the particles, and the next person inhaling those particles.They’re often cough, fever, chills, and body aches.
The vaccine does not contain the actual, infectious flu virus. The vaccine doesn’t infect a person, though some people may feel crummy after getting the shot.“You want your body to think it’s got a real infection,” Turner said. “So that means the virus will turn on all the same pathways that it would if you saw the real flu and then it just can’t cause disease.
“They formalin-fixed the virus, which means they just killed it and they gave a killed virus to babies. So it’s not infectious,” Turner said. “But somehow that vaccine ended up making infection worse. So as soon as that baby saw RSV infection for the first time, it actually responded much more rapidly and more potently and a lot more children got hospitalized.”
