Researchers learn that coronavirus symptoms present themselves in a specific order – which could be a potentially useful tool in helping with earlier detection and self-isolation.
A recent study from the University of Southern California, published in the medical journal Frontier Public Health, found that the virus typically first appears as a fever, followed by cough and muscle aches, progression to nausea and / or vomiting and then diarrhea.
The Aug. 13 study was led by doctoral candidate Joseph Larsen and scientists Peter Kuhn and James Hicks at the Convergent Science Institute at USC Michelson Center in Cancer.

“This sequence is especially important to know when we have overlapping cycles of diseases such as the flu that coincides with COVID-19 infections,” said Peter Kuhn, a USC professor of medicine, biomedical engineering and aerospace and mechanical technique, released in an online press. “Physicians can determine what steps to take to care for the patient, and they can prevent the patient’s condition from deteriorating.”
“Given that there are now better approaches to COVID-19 treatments, patients can identify hospitalization sooner rather than later,” Larsen added in the statement.
Researchers knew that the new data from the study could also help doctors rule out other diseases.
Although fever and cough are often linked to a wide range of illnesses, including flu and other respiratory illnesses, it comes down to the timing at which they appear – followed by the delayed onset of stomach symptoms, the study says.
“The upper GI tract (i.e., nausea / vomiting) appears to be affected before the lower GI tract (i.e., diarrhea) in COVID-19, which is the opposite of MERS and SARS,” scientists wrote in ‘ the study.
The study was funded through the National Cancer Institute and the Carol Vassiliadis Scholarship.
Larsen also had support from USC Dornsife College and the Schlegel Family Endowment Fellowship, the press release added.

Researchers analyzed cases of Coronavirus dating to December 2019

The USC researchers are studying more than 55,000 confirmed cases of coronavirus in China, collected by the World Health Organization, from February 16 to February 24, according to the study. They also analyzed a dataset of roughly 1,100 cases sampled by the China Medical Treatment Expert Group through the National Health Commission of China from December 11, 2019 to January 29. 2020.
The study showed that scientists then compared the chronology of flu symptoms by examining data from 2,470 cases in North America, Europe and the Southern Hemisphere, which were reported to health authorities from 1994 to 1998.
“Our model predicts that flu initiates with cough, while COVID-19 like other coronavirus-related diseases initiates with fever,” the study reads.
Scientists also suggested that “fever should be used to screen for entry” into “facilities” as they begin to open.
The CDC lists a variety of possible COVID-19 symptoms

Although the research focuses on early-onset symptoms, the Centers for Disease Control and Prevention has published a list of common COVID-19 symptoms. People with COVID-19 have reported a wide range of symptoms – ranging from mild to severe illness. Symptoms may appear 2-14 days after exposure to the virus, “CDC wrote, adding,” People with these symptoms may have COVID-19: “
Fever or fever
Cough
Shortness of breath or difficulty breathing
Wurgens
Muscle as body
Headache
New loss of taste or smell
Sore throat
Congestion as a runny nose
Nausea as vomit
Diarrhea
The CDC notes: “This list does not include all possible symptoms. CDC continues to update this list as we learn more about COVID-19. The CDC list has grown as more is learned about coronavirus.
According to the Centers for Disease Control and Prevention, the U.S. reported a total of about 5.2 million coronavirus cases as of Sunday morning – nearly 57,000 up from the day before.
The total death toll from coronavirus was just over 167,000, a rough increase.
Meanwhile, California on Friday became the first state in the U.S. to reach more than 600,000 confirmed COVID-19 cases, resulting in 11,000 total deaths, CBS reported, according to data from Johns Hopkins University.
