10 typical symptoms

Some of the more well-known and commons signs of Covid-19 can be just as dangerous.


An inability to take a deep 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 immediately call your doctor or a local urgent care, experts say.


"If the shortness of breath is severe enough, you should call 911," said American Medical Association president Dr. Patrice Harris.

“如果呼吸短促非常严重,那么你应该拨打911”,美国医学协会主席Patrice Harris表示。

Get medical attention immediately, the CDC says, if you experience a "persistent pain or pressure in the chest," or have "bluish lips or face," a possible sign of a lack of oxygen.


A rising temperature: Fever is a key sign of Covid-19. But don't fixate on a number on the thermometer. Many people have a core body temperature that is above or below the typical 98.6 degrees Fahrenheit (37 degrees Celsius).


Most children and adults, however, will not be considered feverish until their temperature reaches 100 degrees Fahrenheit (37.7 degrees Celsius).


"There are many misconceptions about fever," said Dr. John Williams, chief of the division of pediatric infectious diseases at the University of Pittsburgh Medical Center Children's Hospital of Pittsburgh.

匹兹堡大学匹兹堡儿童医院医疗中心儿科传染病科主任John Williams博士表示:“关于发烧,人们有许多误解。”

"We all actually go up and down quite a bit during the day as much as half of a degree or a degree," Williams said, adding that for most people "99.0 degrees or 99.5 degrees Fahrenheit is not a fever."


Don't rely on a temperature taken in the morning, Schaffner advised, because temperature varies during the day. Instead, take your temperature in the late afternoon and early evening.


"One of the most common presentations of fever is that your temperature goes up in the late afternoon and early evening. It's a common way that viruses produce fever."


A debilitating cough: Coughing is another common symptom, but it's not just any cough, Schaffner said. The cough is bothersome, one that you feel deep in your chest.


"It's not a tickle in your throat. You're not just clearing your throat. It's not just irritated," Schaffner explained. "It's coming from your breastbone or sternum, and you can tell that your bronchial tubes are inflamed or irritated."


Around 60% of the people infected with Covid-19 experienced a dry, peristent cough, likely from irritated lung tissue, according to studies from China. As the disease worsens, the lungs begin to fill with fluid, which might change the nature of the cough.


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 coughed up sputum, a thick mucus sometimes called phlegm, from their lungs, which is also characteristic of the common cold or flu.


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.


Of course that makes it difficult to know if you have the flu or have been exposed to the novel coronavirus. One possible sign that you might have Covid-19 is if your symptoms don't improve after a week or so but actually worsen.


Overwhelming exhaustion: 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.


Diarrhea and nausea: At first science didn't think gastric issues that often come with the flu applied to Covid-19. After all, this is a respiratory disease. But as more research rolled in and the virus was found in stool samples, that opinion quickly 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.

“在一项由中国展开的研究中,研究对象是大约200名Covid-19患者,他们都来自于最早患上Covid-19的一批患者。在研究中,他们发现,大约有一半的患者存在消化或胃部(肠胃)症状:,Gupta在CNN的 “New Day”新闻节目中表示。

Researchers have now found that SARS-CoV-2 can infect cells in the intestine and multiply there. That's likely because, like the lungs, the intestinal lining is loaded with ACE2 receptors, the sweet spot where the spokes of the SARS-CoV-2 virus attach and enter the body's cells.


Sore throat, headache and nasal congestion: The early 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.


While cough, shortness of breath or difficulty breathing are key red flags of Covid-19, the council recommended headache and sore throat fall into a second tier of symptoms that may trigger doctors to consider testing for Covid-19.


That tier kicks in when patients present with two of the following clinical signs: Chills or shivers, fever, muscle pain, headache, sore throat or new loss of taste and smell. If there is no other more appropriate diagnosis, the guidelines say doctors should report those patients as potentially infected with Covid-19.
