Background: Despite global prevention and quarantine efforts, the incidence of COVID-19 disease continues to increase. As a possible cause, our aim was to investigate which parameters increase the sensitivity or protection against COVID-19 between RT-PCR positive and RT-PCR negative cases in patients admitted to the emergency department.
Methods: In the pandemic process, patients admitted to the hospital with suspicion of COVID-19 were evaluated retrospectively. RT-PCR test was divided into + (for Group 1) and - (Group 2). The gender, age, clinical information, application symptoms, and comorbidity data of the patients were evaluated.
Results: One hundred and sixty-seven cases were evaluated in the study. Group 1: 88 cases, M/F ratio: 46/42 and average age 48 ± 17.3 years, Group 2: 79 cases, M/F ratio was approximately 3/2, and the average age was 48.3 ± 19.4 years. When the groups were compared in terms of symptoms, fever, cough, weakness, and headache were prominent in Group 1, whereas the contact was significantly higher in Group 2 (p < 0.05). Among the comorbid diseases, only COPD showed a significant difference between the groups, and it was found significantly higher in Group 2 (p < 0.05).
Conclusions: Cough, headache, and fever were found valuable in the detection of cases. Attention should be paid to contact isolation to circumvent the pandemic process with less damage. Having chronic diseases, especially COPD, increases the risk of infection with SARS-CoV-2. Close monitoring and control of chronic diseases can positively change the course of COVID-19.
