the order of onset of symptoms identified by researchers

Cough and fever are known to be the main symptoms of the new coronavirus Covid-19. Today it’s the order in which symptoms appear that interests scientists. Data that could prove useful to differentiate patients with Covid-19 from those with influenza this autumn for example. ” We hypothesize that the order of symptom onset could help patients and healthcare professionals more quickly diagnose and distinguish Covid-19 from other respiratory illnesses “, Indicate the American researchers from the University of Southern California who published the results of their study in the scientific journal Frontiers in Public Health.

They studied the case of nearly 56,000 Chinese patients affected by Covid-19 (cases all collected by the World Health Organization) in February 2020. The researchers compared the symptoms caused by the coronavirus to 2,500 influenza cases declared by European and American health authorities from 1994 to 1998, and symptoms of the other two coronavirus diseases, SARS (severe acute respiratory syndrome) and Mers (Middle East respiratory syndrome). As a result, they put forward a diagram and established the order of appearance of the symptoms of the new coronavirus. The objective of this study is therefore to make it possible to differentiate the Covid-19 other infectious diseases.

Scientists have chosen to focus on certain symptoms ” easily discernible or objective »Thus excluding the symptoms reported as loss of taste and / or smell. The results of the study make it possible to draw up a list of the signs of a coronavirus infection in chronological order. Scientists warn about how symptoms can vary from person to person, noting that some patients with Covid-19 are asymptomatic.

The order of appearance of symptoms of Covid-19 according to this study:

1. Fever

2. Cough

3. Muscle pain, headache, throat pain

4. Nausea and / or vomiting

5. Diarrhea

The order of appearance of flu symptoms:

1. Cough or muscle pain

2. Headache

3. Sore throat

4. Fever

5. Nausea and / or vomiting and diarrhea

The site maladiecoronavirus.fr, referenced by the Ministry of Health, allows those who think they are infected to take an anonymous and free “test”: 24 questions on their symptoms (fever, cough, breathing difficulties, muscle aches, etc.) but also on their medical history, their age.
