Coronavirus Symptoms Start About Five Days After Infection
Incubation period supports recommendations of a two-week quarantine, according to a Johns Hopkins University study
Most people who catch Covid-19—the disease caused by the novel coronavirus—start showing symptoms roughly five days after infection, disease analysts at Johns Hopkins University said on Monday, in the largest such study of known cases world-wide.
It takes about five days for COVID-19 symptoms to show after contracting the virus.
The vast majority of those infected will develop symptoms within 12 days.
That’s in line with current CDC recommendations that call for patients to remain in quarantine or self-isolation for 14 days after potential exposure.
It takes an average of about five days for COVID-19 symptoms to show after contracting the virus, while the vast majority of people infected will develop symptoms within 12 days, researchers confirmed in a new report published Monday in the journal Annals of Internal Medicine.
The American College of Physicians said 97.5% of people infected with the new coronavirus will show symptoms within 12 days of catching the virus. The average incubation time is five days, researchers said. That’s in line with current Centers for Disease Control and Prevention recommendations that call for patients to remain in quarantine or self-isolation for 14 days after potential exposure.
Researchers from Johns Hopkins Bloomberg School of Public Health analyzed reports from 50 provinces, regions and countries outside of Wuhan, China, to determine the virus’s incubation period. Researchers found 181 confirmed cases with time frames for identifiable exposure and symptom onset.
