The first case of COVID-19 was reported Dec. 1, 2019, and the cause was a then-new coronavirus later on named SARS-Co, V-2. SARS-Co, V-2 might have come from an animal and changed (altered) so it could trigger health problem in people. In the past, a number of contagious disease outbreaks have been traced to infections coming from birds, pigs, bats and other animals that altered to end up being dangerous to humans. Research study continues, and more research study may expose how and why the coronavirus progressed to trigger pandemic disease.
Signs show up in people within 2 to 14 days of direct exposure to the infection. A person infected with the coronavirus is contagious to others for approximately two days prior to symptoms appear, and they remain contagious to others for 10 to 20 days, depending upon their immune system and the intensity of their illness.
