Those with more critical cases of COVID-19 went on to suffer more severe symptoms that last for two more weeks, on average. Phase one encompasses the first seven days of symptoms (see below).

The study showed that 85% of those with the virus only experience “phase one” of the virus’s course.

About 50% felt fatigued and had a dry cough, with 33% having difficulty breathing and complaining of muscle pain. Ninety-nine percent of the patients studied had a fever.

The average duration of fever was 12 days.

A new study from Johns Hopkins Bloomberg School of Public Health suggests a median time of about five days.

The first symptoms begin from two to 14 days after you have been exposed to the virus.

The fever is often followed a few days later by a dry cough, one in which you do not cough up any phlegm, and shortness of breath.

The first symptom of COVID-19 is usually a fever.
