It turned out that there is a 'sequence of onset' in the symptoms of new coronavirus infection

In addition to fever, novel coronavirus infection (COVID-19) is known to exhibit various symptoms such as respiratory symptoms such as coughing and sneezing, strong fatigue (malaise), and loss of taste and smell. I am. A new study of 55,000 infected individuals found that COVID-19 symptoms tended to occur in a particular 'order'.

Study of More Than 55,000 COVID-19 Cases Reveals a Predictable Order of Symptoms

A research team led by Joseph R. Larsen of the University of Southern California conducted research on the order of COVID-19 symptoms. The research team conducted a study to derive the sequence of symptoms from the data of 55,000 confirmed cases of confirmed COVID-19 in China published by the World Health Organization.

As a result, it was confirmed that COVID-19 tended to develop fever in the initial stage, and thereafter, the symptoms tended to progress in the order of cough, myalgia, nausea, vomiting (daughter), and diarrhea.

In addition, the research team is comparing the order of the symptoms of COVID-19 with the order of the symptoms of

SARS and MERS , which are infectious diseases caused by viruses classified as influenza and coronavirus . Influenza tends to have a cough in the early stage and then fever, which is contrary to the order of COVID-19 'fever→cough', and SARS and MERS have the same fever as COVID-19 in the early stage. However, it is different from COVID-19 in that nausea and vomiting occur after diarrhea comes.

Furthermore, when the research team simulated the progress of symptoms for 500,000 people based on the assumption that the symptoms of COVID-19 occur independently, the order of occurrence of symptoms of COVID-19 was ``fever It appears to be different from other prominent respiratory diseases.

'The order of symptoms is important. Knowing that the progression of each disease is different will allow doctors to distinguish COVID-19 from other illnesses sooner,' said lead author Larsen. And comment. Science Alert, a science news media that reported this research, said, 'The Center for Disease Control and Prevention in the United States should 'measure body temperature before meeting people to check if they have a fever'. , 'Fever' should be checked as an initial symptom of COVID-19. The results of this research support this.'
