The term “flurona” made headlines in Israel and is now used around the world.

Some have misunderstood the term to mean a combination of flu and COVID-19 cases.

Dr. Jonathan Grein, an infectious disease physician and director of hospital epidemiology at Cedars-Sinai Medical Center in Los Angeles, said that’s not what’s happening. H said the medical diagnosis is actually a co-infection.

At this point, Dr. Grein says flu and COVID co-infections are nothing to panic about.

“There doesn’t seem to be any major sign that getting infected with both makes you that much sicker, but we just don’t know, and it’s too early to know,” Grein says. “Common sense would dictate getting infected with two things is definitely not good.”

Common symptoms to look for are dry cough, fever, sore throat, headache or body aches, and exhaustion.

Grein says her hospital has only seen a few people with flu and COVID at the same time. Much like co-infections elsewhere in the country, all of the cases were mild and in younger patients, he said.

Experts say it’s because young people have less immunity because they haven’t been exposed to as many viruses.

Unvaccinated people who are very sociable, do not mask are more likely to contract influenza and COVID co-infection. Older and immunocompromised people are more likely to see both diseases become serious.

“There’s a real concern that we’re seeing more flu circulating with COVID-19,” Grein said. “And, I think there’s a real concern that it could really increase the number of people getting seriously ill or having to come to hospital.”

Medical experts are encouraging people to get flu and COVID-19 vaccines to protect against viruses.
