Although we here at Eat This, Not That! Health have answered that question, using the CDC's list as the basis, there is another web authority that often comes up first: WebMD. "Here's what to look for if you think you might have COVID-19," they say, using a China study as their foundation, and remember: "No one symptom is definitive for COVID-19. That's why only a COVID-19 test can say for certain if you're infected." Read on, and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus


You May Develop a Fever

A calling card of COVID, 88% of patients in the China study had a fever (although one is not required). "Normal body temperatures are different for everyone, but they lie within the range of 97 to 99," says WebMD. "A temperature of 100.4 or higher is considered a fever."


You May Have a Dry Cough

A dry cough is just one of the reasons why quarantining yourself is so important. Says WebMD: "Droplets from a cough may travel farther than 6 feet and could potentially carry enough COVID-19 virus to infect another person, according to a new study." 68% of those in the China study had a dry cough.


You May Experience Fatigue

38% of those studied in China reported fatigue—and for some people, it can last. "A little more than half of people who recover from COVID-19 report fatigue, even weeks after they get better, according to a new study published in the journal PLOS One," says WebMD. "Regardless of the severity of their infection, about 52% said they still felt extremely tired 10 weeks after contracting COVID-19."


You May Have Mucus or Phlegm

33% of those in the China study produced mucus of phlegm, and a runny nose and congestion are on the CDC's list of symptoms. "The new coronavirus that causes COVID-19 doesn't usually cause mucus in the chest," reports WebMD. "But complications from the virus can include pneumonia, which does involve chest congestion."


You May Have Shortness of Breath

"For most people, the symptoms end with a cough and a fever," says WebMD. "More than 8 in 10 cases are mild. But for some, the infection gets more severe. About 5 to 8 days after symptoms begin, they have shortness of breath (known as dyspnea)." That happened to 19% of those in the China study.

Body aches or myalgia is another symptom that may last for months, if not years, after contracting COVID. "A British study says many coronavirus patients suffer symptoms such as breathlessness, excessive fatigue, and muscle aches for months after being treated at a hospital," reports WebMD. "Three quarters of a group of patients who received care for coronavirus at Bristol's Southmead Hospital were still suffering ongoing symptoms three months later," according to a news release from the hospital. 35% of those in the China study had body aches.


You May Have a Sore Throat

"Sore throat can also be a symptom of COVID-19, but it is not as common as a fever or a cough," says WebMD. "If you are experiencing any symptoms of COVID-19 or have come in contact with someone confirmed to have COVID-19, you should get tested and self-quarantine until you get the results."


You May Have a Headache

"Headache certainly can be a symptom of COVID-19—but also approximately eleven-million other health conditions," says WebMD. "In fact, that's the problem with trying to diagnose the novel coronavirus based on symptoms alone: no one symptom is definitive for COVID-19. That's why only a COVID-19 test can say for certain if you're infected."


You May Have Chills


"Your body can turn on the chills in response to other infections," says WebMD. "This may help your immune system kick in faster and work better."

Though COVID gastrointestinal symptoms vary widely, they can include loss of appetite, nausea, vomiting, diarrhea and generalized abdominal pain."

1% in the China study coughed up blood. "Hemoptysis is when you cough up blood from your lungs," says WebMD. "It can be a sign of a serious medical condition. Infections, cancer, and problems in blood vessels in your lungs can cause it. Unless you have bronchitis, you need to see a doctor if you're coughing up blood."


You May Get Swollen Eyes

A new study, published in BMJ Open Ophthalmology, found that sore eyes are the most common ocular ailment of coronavirus. Previous studies have established that COVID-19 can manifest itself in the eyes, including conjunctival discharge, eye rubbing, conjunctival congestion, and even pink eye. While other symptoms may be more important, researchers note that the "type, frequency, and ocular transmission of the virus must not be ignored, especially as the eye has been recognized as one of the organs through which the virus might enter the body." 1% in the China study has swollen eyes.

"Cardinal symptoms are the key ones from which a diagnosis is made."
