Abstract

Objective

Under the prevention and control measures of COVID-19, the epidemiological situation of respiratory pathogens is not well known. Understanding the patterns of respiratory pathogens epidemiology under the prevention and control measures of COVID-19 is important to guide resource allocation for existing and future treatment and prevention strategies.

Methods

In total, 659 fever outpatients nasopharyngeal swabs were collected at fever illness onset during June in 2022 at the First Hospital of Guangzhou Medical University. Swabs were tested by real-time fluorescent single-tube multiplex polymerase chain reaction (PCR) for 12 respiratory pathogens. Moreover, 108 of the 659 swabs were tested for influenza virus antigen.

Results

At least one pathogen was detected in 477 (72.38%) of 659 fever outpatients with multiple pathogens identified in 25 (3.79%). The highest multiple infectious pattern is parainfluenza virus in combination with influenza (five cases). Influenza A virus (IFA), human rhinovirus (HRV), and parainfluenza virus are the three leading virus pathogens with proportions of 64.64%, 5.01%, and 2.88%. School-age children and adult groups have the highest pathogens positivity rate of 81.28% and 83.87%.

Conclusion

A high proportion of adolescents and adults has respiratory pathogens detected during fever illnesses during June in 2022 under the prevention and control of COVID-19. These data indicate that diagnosis, prevention, and control of respiratory tract infection should be paid attention under the prevention and control of COVID-19.

2022年6月广州市防控COVID-19流感疫情形势分析

目标在 COVID-19 的预防和控制措施下，呼吸道病原体的流行病学情况尚不十分清楚。了解 COVID-19 防控措施下呼吸道病原体的流行模式对于指导现有和未来治疗和预防策略的资源分配非常重要。方法 2022年6月，广州医科大学附属第一医院共采集了659名发热门诊患者的鼻咽拭子。咽拭子通过实时荧光单管多重聚合酶链反应（PCR）检测 12 种呼吸道病原体。此外，还对 659 份咽拭子中的 108 份进行了流感病毒抗原检测。结果在 659 名发热门诊患者中，477 人（72.38%）至少检测出一种病原体，25 人（3.79%）检测出多种病原体。最多的多重感染模式是副流感病毒合并流感（5 例）。甲型流感病毒（IFA）、人类鼻病毒（HRV）和副流感病毒是三种主要病毒病原体，所占比例分别为 64.64%、5.01% 和 2.88%。学龄儿童和成人组的病原体阳性率最高，分别为 81.28% 和 83.87%。结论在 COVID-19 的预防和控制下，2022 年 6 月期间，青少年和成人在发热疾病中检出呼吸道病原体的比例较高。这些数据表明，在预防和控制 COVID-19 的过程中，应重视呼吸道感染的诊断、预防和控制。
