Both studies agreed that the first and most common symptoms of coronavirus are fever and cough.

The Wuhan University study also found that it could include other symptoms such as fatigue, muscle pain and shortness of breath, as well as less common symptoms such as headache, dizziness, abdominal pain, diarrhoea, nausea and vomiting.

That study also found that 14 of the 138 patients had diarrhea and nausea a day or two before they even developed the first obvious symptoms: fever or shortness of breath, also called dyspnea.

However, according to a Business Insider report, someone could have been infected without showing symptoms for five days or more.

According to a study by the Chinese Center for Disease Control and Prevention, 1.2 percent of coronavirus cases were asymptomatic and 80.9 percent of cases were “considered mild.”

To see what the Wuhan University study and the Jinyintan and Wuhan pulmonary hospitals study, below are the daily symptoms of the coronavirus.

Day 1

According to both studies, the first symptoms experienced by patients are fever and cough.

patients had a fever, nearly 70 percent felt fatigue, 59 percent had a dry cough, nearly 35 percent had muscle pain (or myalgia), and 31 percent had dyspnea in the early stages of the virus.

Day 5

According to the Wuhan University study, the median time between first symptoms and shortness of breath was five days.

Day 7

The study from the Jinyintan and Wuhan pulmonary hospitals found that most patients experienced dyspnea from the seventh day, which lasted between 12 and 13 days.

Meanwhile, the Wuhan University study found that patients need to stay in hospital for about 7 days.

Day 8

Around the eighth day, patients began to develop acute respiratory distress syndrome (ARDS), according to the Wuhan University study.

ARDS occurs when fluid builds up in the lungs and prevents the lungs from getting enough oxygen, according to the Mayo Clinic.

Day 9

The Jinyintan and Wuhan pulmonary hospital study found that after nine days, patients developed sepsis.

Day 10

Meanwhile, the Jinyintan Study and Wuhan Pulmonary Hospitals found that survivors developed ARDS around day 10 and non-survivors developed ARDS around day 12.

It is also around the 10th day that the patients were admitted to the intensive care unit, according to the Wuhan University study.

The study also found that the average hospital stay was about 10 days.

Day 12

The Jinyintan and Wuhan pulmonary hospital study found that the initial fever lasted about 12 days, but the cough lasted about 19 days.

Day 22

According to the study from the Jinyintan and Wuhan pulmonary hospitals, it took approximately 22 days for the survivors from when they contracted COVID-19 until they were discharged from the hospital.
