The \u201cincubation period\u201d means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days. These estimates will be updated as more data become available. <\/p>\n\n\n\n
Researchers\u00a0first isolated a coronavirus\u00a0in 1937. They found a coronavirus responsible for an infectious\u00a0bronchitis\u00a0virus in birds that had the ability to devastate poultry stocks.<\/p>\n\n\n\n
Scientists first found evidence of human coronaviruses (HCoV) in the 1960s in the noses of people with the common cold. Two human coronaviruses are responsible for a large proportion of common colds:\u00a0OC43 and 229E.<\/p>\n\n\n\n
