New Crown asymptomatic infected patients are usually those who have no clinical symptoms themselves, but have a positive nucleic acid test result. Some patients can be detected within 3 to 7 days, but it is not excluded that some patients are detected within 7 to 14 days. Usually, when the body is infected by the novel coronavirus, a positive test can be detected 3 to 7 days after infection. Since asymptomatic patients have stronger body immunity, they do not show clinical symptoms when the test is performed, but their test results are positive. However, there are some cases where asymptomatic infected patients are detected within 7 to 14 days. This is because asymptomatic patients may not be detected at an early stage when they have a strong resistance or when the incubation period of the virus in their body is long. However, since the incubation period of the novel coronavirus usually does not exceed 14 days, that portion of infected individuals will be detected in 7 to 14 days. Since the incubation period of the virus varies among individuals, it is advisable to isolate yourself at home or go to a designated healthcare facility for testing to prevent the spread of the virus when you are suspected to be a close contact.
