These clinical features indicate that the absence of these symptoms in an individual does not rule out the diagnosis of COVID-19. If a person has a history of exposure to the virus regardless of the symptoms that he shows, he should be kept under medical observation, isolated from others, and examined thoroughly [16]. The diagnosis should be made on history, examination, symptoms, and certain investigations that are necessary and gold standard in virus detection (RT-PCR, CT scan, POCT of IgG and IgM, ELISA, and blood culture) [4].
