Research in the journal Annals of Internal Medicine has shown that people infected with SARS-CoV-2 will have symptoms after 5 days of exposure to a specific virus and outbreak after 2 weeks.
CNN cited a study published March 9 in the Annals of Internal Medicine, where people infected with the corona virus tend to exhibit symptoms between 5 and 2 weeks after infection. Associate professor of epidemiology at Johns Hopkins Bloomberg School of Public Health, Justin Lessler, an author of the study, said this time is consistent with previous estimates from public health agencies and the results for See, a 14 days isolation period for those suspected of coronavirus is necessary.
To estimate the incubation period, the researchers studied more than 180 reports of coronavirus in non-viral areas of widespread infection. These are places that are likely to be infected with Covid-19 due to travel or travel.
However, research conducted at the beginning of the Covid-19 epidemic has only produced results based on the analysis of Covid-19 cases outside Hubei Province, China reported 4 months ago. 1 to 24 February.
Most of the cases (161 out of 181 people studied) had a recent travel or residence history in Wuhan, China. Other patients had a history of contact with tourists from Hubei or those infected with Covid-19 from this locality. Among the onset of symptoms, the average time from onset to admission was 1.2 days.
The study results also showed that the average incubation period was estimated to be 5.1 days and 97.5% of patients detected specific symptoms in about 11.5 days.
The estimates underpin the 14 days isolation rule issued by WHO and health authorities around the globe.
