Why are so many people sick with COVID-19, flu and RSV? Health experts weigh in

According to the Centers for Disease Control, in most U.S. states, respiratory illness levels are currently “high” or “very high."

YORK, Pa. — According to the Centers for Disease Control, in most U.S. states, respiratory illness levels are currently “high” or “very high.” COVID-19, flu and RSV cases have been on the rise, and health experts say it’s common for the time of year. 

“It’s cold and flu season, so we very commonly see respiratory illnesses of all kinds, but particularly COVID, flu and RSV,” said Dr. John Goldman. 

Dr. Goldman says the illnesses tend to spread because many people are in enclosed areas due to colder temperatures and weather changes. Being in close spaces allows the virus to spread amongst people, causing a rise in respiratory illnesses and infections. 

“Diseases that are spread through air are spread more efficiently inside than outside,” said Dr. Goldman. 

Although there is a rise in these cases, Dr. Goldman says our area has hit its peak, and cases of the three illnesses should be on a decline very soon. The spike hit a high specifically with an increase in COVID-19 and flu cases. 

“Part of it is, all of these diseases tend to spread from South to North, so I think the number that is coming down nationally--our area will come down a little bit later,” said Dr. Goldman. 

As for hospitalizations, those numbers have not risen. Dr. Goldman says at UPMC Hospitals, they’re seeing fewer patients who come in with COVID-19, flu or RSV. With these three illnesses on the rise, it’s also hard to tell what sickness a person has if they were to self-diagnose. Dr. Goldman says there aren’t many differentiating factors but one. 

“The only thing is that if you lose your taste or your sense of smell, it is likely that you have COVID, but if you haven't lost them and you think have a cold--you can have any three of those viruses,” said Dr. Goldman. 

UPMC recommends taking an at-home COVID-19 and flu test to help diagnose your symptoms. They’re also encouraging anyone who is sick to stay home and prevent the spread, and wash their hands and disinfect surfaces frequently. 

“I would also encourage you to get your vaccination,” said Dr. Goldman. “Patients who are high risk or above the age of 65--if you get a flu shot, your chances of dying from the flu go down by about half,” said Dr. Goldman.
