With coronavirus continuing to spread around the nation, identifying symptoms of the illness is crucial for early detection and treatment.
Now researchers have uncovered the order that COVID-19 symptoms are most likely to show up in an infected individual.
According to scientists at the USC Michelson Center for Convergent Bioscience, a person with the novel virus will usually first experience fever, then cough and muscle pain, followed by nausea, and/or vomiting, and diarrhea, reported CBS News.
"This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with infections of COVID-19,'' Peter Kuhn, a USC professor of medicine, biomedical engineering, and aerospace and mechanical engineering told ABC News.
"Doctors can determine what steps to take to care for the patient, and they may prevent the patient's condition from worsening.''
The study, published in the medical journal Frontier Public Health, analyzed data from 55,000 positive cases of the virus in China over a nine-day period in February. The researchers also looked at medical records from another 1,100 cases collected in December and January.
For comparison, the study also examined 2,470 influenza cases in North America, Europe and the Southern Hemisphere, which were collected between 1994 to 1998.
While not everyone experiences all coronavirus symptoms (or any at all), medical experts stressed the importance of knowing the order.
“Besides the things that we all talk about like loss of smell and loss of taste, again — fever, cough, muscle aches, nausea, vomiting and then diarrhea are very good indicators of the fact that you may have COVID-19." Dr. Bob Lahita told CBS.
As we head into flu season, the CDC is also recommending everyone get the flu vaccine this year as a preventative measure amid the pandemic.
As of Saturday, the United States has seen more than 5.3 million cases of COVID-19, with at least 168,761 deaths, according to Johns Hopkins University.
