Assessment of changes in the epidemiology and prognosis of non-SARS-CoV-2 respiratory infections one year after recovery from COVID-19

BACKGROUND: Given its pathophysiology and evidence on its long-term effects, coronavirus disease 2019 (COVID-19) may have altered the incidence, types, and severity of other respiratory infections (RIs). Therefore, this study aimed to evaluate the potential impact of COVID-19 on non-SARS-CoV-2 RIs in COVID-19 survivors. METHODS: This cross-sectional study was conducted using a self-administered, online survey from February 2022 to April 2022 in the United Arab Emirates. Participants included adults diagnosed with COVID-19 before February 2021. Those who did not undergo nasopharyngeal swab tests for contraction of other RIs after recovering from COVID-19 were excluded. RESULTS: Of the 384 participants, 24.5% were aged 18–24 years, and 55.5% were women. The mean body mass index (BMI) was 29.6 ± 3.7 kg/m(2). Among the participants, 34.4% experienced at least one non-SARS-CoV-2 RI after recovering from COVID-19, of which 25.8% reported that the RI lasted longer than those previously, 27.3% sought physician advice, 31.8% reported increased coughing as a symptom of the non-SARS-CoV-2 RI, and 38.6% reported increased sputum. Based on patient responses, the degree of COVID-19 severity was significantly associated with non-SARS-CoV-2 RIs (p = 0.003), and depression was found to be a significant predictor of changes in shortness of breath symptoms (adjusted odds ratio [AOR] = 1.29; 95% confidence interval [CI], 1.17–1.46). CONCLUSIONS: The participants of this study reported changes in the duration and severity of non-SARS-CoV-2 RIs after recovering from COVID-19. Further research is needed to confirm these findings, which suggest a need for swift action to protect the public against RIs, particularly seasonal pathogens.
