The research was conducted on a sample of 181 infected citizens of Hubei province in China. Despite the fact that in most cases the disease is confirmed within 11 days of exposure, a fourteen-day quarantine is a sensible measure.

Recent research from scientists at Johns Hopkins University has shown that the average incubation period of COVID-19 is 5.1 days. With this discovery, a two-week quarantine could seem like a waste of time and money.

Research was conducted with the participation of 181 infected in Hubei province in China. Basic parameters such as probable time of infection and onset of basic symptoms were examined. Based on this, the team designed the incubation period model.

The incubation period is by default the period between exposure and the appearance of the first symptoms. During this time, the patient is normally non-infectious. This cannot be confirmed with certainty about the new coronavirus yet. However, several asymptomatic cases of coronavirus have been reported. By default, virus transmission is droplet-like, as well as related viral diseases.

According to a study published in the Annals of Internal Medicine, symptoms appear in 97.5% of cases within 11.5 days. Of this, only 2.5% of patients show symptoms after 2.2 days.

"A fourteen-day quarantine is a sensible solution. Even if a shorter period would be enough for most patients," said epidemiologist Justin Lessler for ScienceAlert.

Similar investigations are important for a wide variety of measures to prevent the spread of the virus. However, it is necessary to carry out a larger study on a wider sample of the population in order to have clearer conclusions.
