ABSTRACT

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections were not prevalent in Yonago and its vicinity during autumn 2020, and the relative frequencies of pathogen-induced respiratory infections during this period are unclear.

Methods:

We collected 109 nasopharyngeal swabs from 93 pediatric patients who visited Tottori University Hospital between October 1, 2020, and March 31, 2021. These samples were comprehensively tested for 18 pathogens with the FilmArray® respiratory panel test (v2.1) using nested real-time polymerase chain reaction, and the frequency of pathogens detected per month was calculated. In addition, we compared the duration of fever and the blood test results of patients infected with each pathogen or multiple pathogens.

Results:

Of the 109 samples, 42 were obtained from female patients and 67 from male patients (median age, 3 years; range, 0-15 years). Overall, 62 patients (56.9%) had a fever ≥ 38 °C at the time of examination, and the median duration of fever ≥ 38 °C was 2 days (1-12). During the study period, the highest number of samples (22) were collected in November 2020. Among samples that tested positive, the most common pathogens were rhino/enteroviruses (52 samples; 76.5%), followed by adenoviruses (7 samples; 10.3%), coronavirus NL63 (6 samples; 8.8%), coronavirus OC43, parainfluenza virus type 1, and parainfluenza virus type 2 (1 sample each; 1.5% each). The duration of fever was significantly longer in adenovirus-infected patients than in patients infected with other viruses (P < 0.05). Hemoglobin and sodium levels were also significantly lower among the adenovirus-infected patients. However, these variations were mostly within the normal range. No clinically meaningful differences were found between rhino/enterovirus-infected and non-rhino/enterovirus-infected cases, between coronavirus NL63-infected and non-coronavirus NL63-infected cases, and between cases with multiple- and single-pathogen infections.

Conclusion:

Rhino/enteroviruses were the most common viruses causing respiratory tract infections in areas without endemic SARS-CoV-2.
