Usually, checking your symptoms online can spark more anxiety: Is it a cold? The flu? Something entirely more frightening?

With coronavirus though, fears have reached a fever pitch, and many aren’t taking any chances.

And so, surprising absolutely no one, visits to WebMD’s “symptom checker” site are up. What is surprising, though, is just how many people visited the page: A spokesperson for the site told The Post that visits rose 67,000% between early January before the disease began to spread and the week of March 1. Sixty-seven thousand!

According to the CDC, coronavirus symptoms may appear anywhere from two to 14 days after exposure. Generally, people have reported an unrelenting fever and cough as the most immediate symptoms.

But aren’t those also the symptoms of a cold? And the flu? Yes, according to the CDC, and the differences are slim. Shortness of breath appears to be the most obvious difference between the two viruses, in addition to weakness or lethargy.

Flu symptoms can start fast and furious and can include fever, chills, cough, sore throat, stuffy nose, muscle or body aches, headaches and fatigue. Cold symptoms can be similar, the agency notes, but usually much more mild. People with a cold are more likely to also have a runny or stuffy nose, the CDC says.

Doctors at Johns Hopkins University in Baltimore note that the symptoms of coronavirus and the flu are very similar, but the mortality rate of COVID-19 “is thought to be higher than that of most strains of the flu,” and since this is a new virus, “people do not have immunity to it, and a vaccine may be many months away.”

The similarities could be why people are researching their symptoms online.

According to WebMD reps, visitors searched “sore throat” and “runny nose” the most on the checker site. From Jan. 12 to March 1, visits to the overall site rose by 3,583%, according to WebMD.

The best way to prevent coronavirus, according to the CDC, is to practice good hand-washing hygiene, stay home when you’re sick, avoid people who are ill and to quit touching your face.

In the meantime, don’t be a hero and go to work anyway if you’re feeling ill. Many in New York’s fashion scene are doing self-quarantines after returning from Milan for fashion week. Italy, which is in the midst of a major outbreak of coronavirus, announced today that the country has closed all schools and universities.
