In Ohio, there have been 10,540 people hospitalized since October with flu symptoms.
While flu numbers in Ohio are at this point higher than COVID-19 numbers, the coronavirus that’s part of the outbreak is more contagious and spreading at a much faster through the population, with no vaccine and no built up immunity to the new coronavirus. A higher percentage of COVID-19 patients need advance care, such as in an ICU, leading Ohio to brace for an unprecedented spike in hospitalizations.

To some, that comparison seems comforting because flu is such a familiar foe. President Donald Trump regularly brings it up, noting in a tweet how many more Americans die from flu and adding, “Nothing is shut down, life & the economy go on … Think about that!”
But to public health experts, the huge number of flu deaths is exactly why extraordinary steps should be taken to try to prevent the new coronavirus from spreading widely.
The flu’s annual return can’t be stopped because it’s already so embedded in the population. There is still a chance COVID-19 cases can be limited or spread slowed while treatments are developed.
HOW DEADLY ARE THE VIRUSES?
Flu kills about 0.1% of those it infects, but that’s still hundreds of thousands of people each year because it infects millions.
Researchers are still trying to understand just how deadly the new coronavirus is. The mortality rate from infection with the virus isn’t known yet because the cases caught in an early part of an outbreak are often the most severe, people with mild or no symptoms aren’t being tested, and sometimes overwhelmed hospitals struggle to care for the sickest patients. Various reports have estimated the fatality rate from less than 1% to as high as 4% among cases diagnosed so far, depending on location.
Most people infected by the new coronavirus develop mild or moderate symptoms and recover after about two weeks.
SO WHAT DO I HAVE?
Flu, cold and coronavirus often share certain symptoms, but differences in intensity and how they appear
can offer clues to which one is causing the misery. Doctors can test for the flu and get results within a day, but coronavirus testing is still limited by availability in the United States.
Colds are often suspected because adults get about two on average each year, said LeRoy, a family medicine doctor and associate dean at Wright State University in Dayton, Ohio.
“The common cold just starts out with a sore or scratchy throat, cough, runny nose, stuffy nose” and any fever is usually mild, he said.
Flu symptoms are more intense and usually come on suddenly, the Yale New Haven Health System advises. They can include a high fever (over 100.5 degrees), extreme exhaustion, muscle or body aches, a dry cough and chills.
“It really hits you like a bus,” and people may start a day well but feel terrible by afternoon, LeRoy said.
Flu symptoms can include a runny or stuffy nose, headaches and possibly vomiting or diarrhea, though the latter two are more common in children than adults, the U.S. Centers for Disease Control and Prevention says.
Symptoms of COVID-19 may appear more slowly. They usually include fever, a dry cough and noticeable shortness of breath, according to the World Health Organization. A minority of cases develop pneumonia, and the disease is especially worrisome for the elderly and those with other medical problems such as high blood pressure, obesity, diabetes or heart conditions.
One study of hospitalized patients in China found that about half did not have a fever when they were admitted but nearly all developed one.
WHAT TO DO IF YOU’RE SICK
Don’t go straight to your doctor’s office — that just risks making more people sick, officials urge. Call ahead, and ask if you need to be seen and where.
Fever, cough and noticeable shortness of breath — “if you have those three components, especially if it’s associated with some recent travel or someone you know who’s been exposed to COVID-19, those things should prompt you to call for medical attention,” LeRoy said.
“Mildly ill patients should be encouraged to stay home,” the CDC’s Dr. Sue Gerber told doctors on a conference call last week. People having difficulty breathing should seek care, and older people or those with other conditions should contact their doctors early in the course of illness, she said.
To protect yourself, wash your hands well and often, keep them away from your face, and avoid crowds and standing close to people.
There’s one big difference between flu and coronavirus: A vaccine exists to help prevent the flu and it’s not too late to get it. It won’t protect you from catching the coronavirus, but may put you in a better position to fight it.
“You don’t want to have a compromised immune system if you were to encounter coronavirus,” LeRoy said.
