By now, you most likely already know all of the symptoms of the coronavirus, and if you don't, you are in luck because they will be listed out in the most typical order of onset.
For those that don't know, coronavirus symptoms can be a range of different things. Researchers have boiled the most common COVID-19 symptoms to three; fever, a dry cough, and shortness of breath. It should be noted that these symptoms won't appear immediately after the infection takes place, as the virus has an incubation period of about five days.
Other COVID-19 symptoms include the loss of taste or smell, sore throat, congestion, diarrhea, fatigue, and muscle or body aches. Now, researchers from China have identified a pattern of which symptoms appear first over a 27 day period. The Chinese researchers were able to do this after examining thousands of COVID-19 patients.
Thanks to BusinessInsider for the breakdown:
- Day 1: Symptoms start off mild. Patients usually experience a fever, followed by a cough. A minority may have had diarrhoea or nausea one or two days before this, which could be a sign of a more severe infection.
- Day 3: This is how long it took, on average, before patients in Wenzhou were admitted to the hospital after their symptoms started. A study of more than 550 hospitals across China also found that hospitalized patients developed pneumonia on the third day of their illness.
- Day 5: In severe cases, symptoms could start to worsen. Patients may have difficulty breathing, especially if they are older or have a preexisting health condition.
- Day 7: This is how long it took, on average, for some patients in Wuhan to be admitted to the hospital after their symptoms started. Other Wuhan patients developed shortness of breath on this day.
- Day 8: By this point, patients with severe cases will have most likely developed shortness of breath, pneumonia, or acute respiratory distress syndrome, an illness that may require intubation. ARDS is often fatal.
- Day 9: Some Wuhan patients developed sepsis, an infection caused by an aggressive immune response, on this day.
- Days 10-11: If patients have worsening symptoms, this is the time in the disease's progression when they're likely to be admitted to the ICU. These patients probably have more abdominal pain and appetite loss than patients with milder cases.
- Day 12: In some cases, patients don't develop ARDS until nearly two weeks after their illness started. One Wuhan study found that it took 12 days, on average, before patients were admitted to the ICU. Recovered patients may see their fevers resolve after 12 days.
- Day 16: Patients may see their coughs resolve on this day, according to a Wuhan study.
- Day 17-21: On average, people in Wuhan either recovered from the virus and were discharged from the hospital or passed away after 2.5 to 3 weeks.
- Day 19: Patients may see their shortness of breath resolve on this day, according to a Wuhan study.
- Day 27: Some patients stay in the hospital for longer. The average stay for Wenzhou patients was 27 days.
