Researchers identify the symptoms of Coronavirus in order, beginning with a fever and cough


University of Southern California researchers have identified the likely arrangement in which symptoms of COVID-19 first appear, represented by fever, coughing, muscle pain, then nausea, or vomiting and diarrhea. According to the scientists, knowing the order of symptoms of COVID-19 may help patients seek care immediately. Or isolate themselves.

According to the study led by the USC Michelson Center for Convergent Biological Sciences in American Cancer, this arrangement may also help doctors rule out other diseases, and knowing the order of symptoms could also help doctors plan how to treat patients and possibly intervene early in the disease.

Corona symptoms as arranged by scientists

The researchers at the University of Southern California: “This arrangement is particularly important to know when we have overlapping cycles of diseases such as influenza that coincide with COVID-19 infection, and doctors can determine the steps to take to care for the patient, and may prevent the deterioration of the patients’ condition.”

“Given that there are now better approaches to COVID-19 treatments, identifying patients early can reduce recovery time,” said the study’s lead author.

Fever and cough are often associated with a variety of respiratory diseases, including Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS), but the timing and symptoms in the upper and lower digestive tract distinguish COVID-19.

The scientists wrote: “It appears that the upper digestive system (nausea / vomiting) was affected before the lower digestive system (ie diarrhea) in COVID-19, which is the opposite of what happens with other coronavirus diseases, MERS and SARS.”

To compare the ranking of COVID-19 symptoms with influenza, the researchers examined data from 2,470 cases in North America, Europe and the Southern Hemisphere that were reported to health authorities from 1994 to 1998, according to results published in Frontiers in Public Health.
