Diagnostic accuracy of PCR test and symptoms of the disease for covid-19 by Multivariate Roc Analysis

The

new coronavirus disease (Covid-19) is a new viral respiratory tract disease

that was first identified with high fever and shortness of breath in Wuhan,

China, on January 13, 2020. It is known that the disease is transmitted by

droplets and contact. It is defined as a pandemic due to the global epidemic. The

new coronavirus is a type of coronavirus family that can affect both animals

and humans. In retrospect, some different viruses from the coronavirus family

seem to cause severe respiratory diseases such as MERS (Middle East Respiratory

Syndrome) and SARS (Severe Acute Respiratory Syndrome). A total of 160

individuals, 89 men and 71 women, who applied to the hospital with suspicion of

Covid-19, were asked about the possible complaints of the patients in line with

the results of tomography and PCR, and the answers received were recorded. As a

result of the tomography test, which is the gold standard test, a total of 14

cases were positive and 146 cases were negative. Considering the areas under

the curve as a result of Roc analysis, PCR = 0.871, Loss of Taste or Smell =

0.813, Shortness of Breath or Difficulty Breathing = 0.762, Fever = 0.712,

Cough = 0.613 and Sore Throat = 0.598 values were obtained respectively. <o:p></o:p>
