Ethiological, Clinical and Epidemiological Overview of Covid-19 Pandemia

Abstract

The cause of COVID-19 disease has been named as the SARS-CoV-2 virus, which is defined in the category of betaCOV viruses. The disease has been declared as a COVID-19 pandemic by the World Health Organization (WHO). Coronaviruses (CoV) are viruses, some of which are zoonotic, have a crown-like appearance under an electron microscope and contain a single stranded RNA genetic material. The SARS-CoV-2 virus that causes COVID-19 is transmitted through respiratory droplets and direct contact with people. Contagious from the presymptomatic period, COVID-19 can be presented with the symptoms of simple upper respiratory tract infection; it may as well cause severe disease characterized by severe respiratory failure. While the first step in radiological evaluation is x-ray, examination of the lungs with computed tomography has diagnostic value. Prevention is important because there is no medical treatment and immunization method specific to the disease. The most important factor in protection is to limit the exposure to the virus. Therefore, attention is constantly paid to the importance of personal protectors and hygiene.
