10 symptoms of coronavirus
(KYMA, KECY)- Fever, cough, and shortness of breath are found in a majority of COVID-19 (coronavirus) cases.
According to CNN, scientists learn more each day about the mysterious symptoms of coronavirus, the disease that causes it.
Symptoms can appear anywhere from two to 14 days after being exposed to the virus, according to US Centers for Disease Control and Prevention.
Here are 10 signs that you or a loved one may have COVID-19 -- and what to do to protect yourself and your family.
Shortness of Breath
Shortness of breath is not usually an early symptom of COVID-19, but it is the most serious. It can occur on its own, without a cough. If your chest becomes tight or you begin to feel as if you cannot breathe deeply enough to fill your lungs with air, that's a sign to act quickly, experts say.
"If there's any shortness of breath immediately call your health care provider, local urgent care or the emergency department," said American Medical Association president Dr. Patrice Harris.
Fever is a key sign of COVID-19. Because some people can have a core body temperature lower or higher than the typical 98.6 degrees Fahrenheit (37 degrees Celsius), experts say not to fixate on a number.
Don't rely on a temperature taken in the morning, said infectious disease expert Dr. William Schaffner, a professor of preventative medicine and infectious disease at Vanderbilt University School of Medicine in Nashville. Instead, take your temperature in the late afternoon and early evening.
"Our temperature is not the same during the day. If you take it at eight o'clock in the morning, it may be normal," Schaffner explained.
Coughing is another common symptom, but it's not just any cough.
"It's not a tickle in your throat. You're not just clearing your throat. It's not just irritated," Schaffner explained.
The cough is bothersome, a dry cough that you feel deep in your chest.
A report put out by the World Health Organization in February found over 33% of 55,924 people with laboratory-confirmed cases of COVID-19 had coughed up sputum, a thick mucus sometimes called phlegm, from their lungs.
Chills and Body Aches
Not everyone will have such a severe reaction, experts say. Some may have no chills or body aches at all. Others may experience milder flu-like chills, fatigue and achy joints and muscles, which can make it difficult to know if it's flu or coronavirus that's to blame.
One possible sign that you might have COVID-19 is if your symptoms don't improve after a week or so but actually worsen.
Speaking of worsening signs, the CDC says a sudden confusion or an inability to wake up and be alert may be a serious sign that emergency care may be needed. If you or a loved one has those symptoms, especially with other critical signs like bluish lips, trouble breathing or chest pain, the CDC says to seek help immediately.
At first science didn't think diarrhea or other typical gastric issues that often come with the flu applied to the noval coronavirus, also known as SARS-CoV-2. As more research on survivors becomes available, that opinion has changed.
"In a study out of China where they looked at some of the earliest patients, some 200 patients, they found that digestive or stomach GI (gastrointestinal) symptoms were actually there in about half the patients," Gupta said on CNN's New Day news program.
Overall, "I think we're getting a little bit more insight into the types of symptoms that patients might have," Gupta said.
The study described a unique subset of milder cases in which the initial symptoms were digestive issues such as diarrhea, often without fever. Those patients experienced delays in testing and diagnosis than patients with respiratory issues, and they took longer to clear the virus from their systems.
Research from China, South Korea and other parts of the world indicate that about 1% to 3% of people with COVID-19 also had conjunctivitis, commonly known as pink eye.
Conjunctivitis, a highly contagious condition when caused by a virus, is an inflammation of the thin, transparent layer of tissue, called the conjunctiva, that covers the white part of the eye and the inside of the eyelid.
But SARS-CoV-2 is just one of many viruses that can cause conjunctivitis, so it came as no real surprise to scientists that this newly discovered virus would do the same.
Still, a pink or red eye could be one more sign that you should call your doctor if you also have other telltale symptoms of COVID-19, such as fever, cough or shortness of breath.
Loss of Smell and Taste
In mild to moderate cases of coronavirus, a loss of smell and taste is emerging as one of the most unusual early signs of COVID-19.
A recent analysis of milder cases in South Korea found the major presenting symptom in 30% of patients was a loss of smell. In Germany, more than two in three confirmed cases had anosmia.
It has long been known in the medical literature that a sudden loss of smell may be associated with respiratory infections caused by other types of coronaviruses, so it wasn't a surprise that the novel coronavirus would have this effect, according to ENT UK (PDF), a professional organization representing ear, nose and throat surgeons in the United Kingdom.
For some people, extreme fatigue can be an early sign of the novel coronavirus. The WHO report found nearly 40% of the nearly 6,000 people with laboratory-confirmed cases experienced fatigue.
Fatigue may continue long after the virus is gone. Anecdotal reports from people who have recovered from COVID-19 say exhaustion and lack of energy continue well past the standard recovery period of a few weeks.
Headache, Sore Throat, Congestion
The WHO report also found nearly 14% of the almost 6,000 cases of COVID-19 in China had symptoms of headache and sore throat, while almost 5% had nasal congestion.
Certainly not the most common signs of the disease, but obviously similar to colds and flu. In fact, many symptoms of COVID-19 can resemble the flu, including headaches and the previously mentioned digestive issues, body aches, and fatigue.
Still, other symptoms can resemble a cold or allergies, such as a sore throat and congestion. Most likely, experts say, you simply have a cold or the flu -- after all, they can cause fever and cough too.
