According to the Express reports, researchers identified a distinct order of systems among COVID-19 patients, a fever followed by a cough. For the seasonal flu, on the other hand, people generally develop a cough before a fever.

The common cold is more likely to begin with a sore throat as the first symptom of illness, as told by the Centers for Disease Control and Prevention (CDC) Allergies abruptly come on and include itchy eyes, sneezing, a runny nose and post-nasal drip.

First Symptom of Each Illness:

COVID-19 - fever

Flu - cough

Cold - sore throat

Allergies - itchy eyes, sneezing, runny nose and post-nasal drip all at once.

The study identifies these as the first symptoms to appear in each condition. However, caution is given, as not everybody with COVID-19 will develop a fever.

In addition, some flu sufferers may not come down with a cough, which is why the length of time symptoms take to appear could be another clue.

The CDC outlined the main differences in the onset of symptoms in COVID-19 and the flu. COVID-19 symptoms can take longer to appear than flu symptoms, up to five days following infection.

However, COVID-19 symptoms could appear as early as two days or as late as 14 days after becoming infected.

The flu symptoms can take up to four days following infection, and a person is usually contagious the day before symptoms appear.

People with the flu can remain contagious for up to seven days after infection. COVID-19 is still under investigation as to how long a person with the disease is contagious. What we do know is that COVID-19 is up to three times more contagious than the flu.

Unfortunately, the researchers from Southern California attested that "a large number of others are asymptomatic", who can still spread the disease.
