For those who have not been infected by the novel coronavirus, much confusion lies as to what are the first typical symptoms to spot, how these symptoms progress and how the infection can become worse. Medical staff from a hospital in China were able to compile a day-to-day diary of the COVID-19 infections and how it affected the patients in the hopes to offer more clarity regarding the deadly virus.
A day-by-day breakdown
After observing thousands of patients during China’s outbreak of COVID-19 earlier this year, hospitals were able to identify a pattern of symptoms.
A day-by-day breakdown of the symptoms of COVID-19 include:
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 pre-existing 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 (ARDS), 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 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.
