ROLE OF CT DIAGNOSIS IN OGK PATHOLOGY IN COVID-19 ON THE EXAMPLE OF A CLINICAL CASE WITH A NEGATIVE PCR TEST IN THE EARLY PERIOD OF ILLNESS

Abstract

On December 31, 2019, the World Health Organization was informed of the discovery of cases of pneumonia caused by an unknown pathogen, and on January 3, Chinese services reported 44 cases of pneumonia to WHO in Wuhan, Hubei province [37]. The pathogen turned out to be a new coronavirus (now known as SARS-CoV-2, previously under the temporary name 2019-nCoV [1]), which had not previously been detected in the human population [38]. On 30 January 2020, in response to the outbreak, WHO declared an international health emergency [38], and on 28 February 2020, WHO raised its global risk assessment from high to very high [26]. On March 11, 2020, the epidemic was declared a pandemic [29].
