As state opens after lockdown, coronavirus cases increase in Florida
Researchers at the University of Southern California claim to have discovered that the symptoms COVID-19s tend to appear in a specific order, a finding that could allow earlier detection and treatment for many patients.
“It’s a good guide in a way,” Dr. Bob Lahita, a professor of medicine who is not affiliated with the study, told CBSN presenter Anne-Marie Green. “We can safely say, studying like they did, I think it was 55,000 patients from China, they looked at the data and looked at the symptoms and found that this order was quite reproducible.”
According to the study, published in the medical journal Frontier Public Health, the most likely order of symptoms is: fever, then cough and muscle pain, followed by nausea and / or vomiting, then diarrhea.
“Fever is number one, followed by cough, followed by aches and pains – and they don’t all have to appear in order, they can appear together,” Lahita said of Group One. symptoms. After that, he says, comes nausea and vomiting, followed by diarrhea.
Not all patients have the same set of symptoms. But the new findings help highlight how COVID-19 differs from other well-known diseases. While fever and cough are also associated with a number of other illnesses, such as the flu, the study notes that this was when these symptoms appeared, and later. gastrointestinal symptoms, which distinguishes this virus.

In a press release on the study, USC scientist Peter Kuhn said that understanding the order of viral symptoms is useful during “overlapping disease cycles” such as upcoming flu season.
“Doctors can determine what steps to take to take care of the patient and they can prevent the patient’s condition from worsening,” Kuhn said.
To uncover the sequence, USC researchers, led by doctoral student Joseph Larsen, examined medical records and other data on more than 55,000 cases of coronavirus in China collected over a nine-day period in February, as well as ‘a set of more than 1000 cases from December to January. They also compared their results to data on 2,470 influenza cases in North America, Europe and the southern hemisphere from 1994 to 1998.
“It is important to have this information,” Lahita said. “Besides the things we all talk about like loss of smell and loss of taste, again – fever, cough, muscle pain, nausea, vomiting and then diarrhea are very good indicators that you may have COVID-19. ”
