Acute respiratory infections (ARIs) and severe acute respiratory illness (SARI) are public health burdens globally. The percentage of non-SARS CoV-2 respiratory viruses among patients having ARI and SARI who visit Car Nicobar's hospital settings is undocumented. Changes in the epidemiology of other respiratory viruses during COVID19 pandemic is being reported worldwide.
Inpatient and outpatient settings at BJR hospital, Car Nicobar Island, India, were used to conduct prospective monitoring for ARI and SARI among Nicobarese tribal members. The patients with ARI and SARI were enlisted in BJR hospital from June 2019 to May 2021. At the ICMR-NIV in Pune, duplex RT-PCR assays were used to test the presence of respiratory viruses. The prevalence of non- SARS CoV-2 respiratory viruses was measured by comparing here between pandemic and pre-pandemic periods.
During the COVID19 pandemic, Influenza A (H3N2) and rhinovirus were predominantly reported non-SARS CoV-2 respiratory viruses while Human metapneumovirusand influenza A (H1N1)pdm09were most commonly reported in the prepandemic period. This result indicates the altered circulation of non-SARS CoV-2 during pandemic.
A considerable proportion of respiratory infection was correlated with respiratory viruses. Prevalence of non-SARS CoV-2 respiratory viruses was high at the time of infection when compared with pre-pandemic period, at Car Nicobar Island. This study enlightened the change in circulation of other respiratory viruses among the indigenous Nicobarese tribes. Clinicians and allied medical staff should be more prudent of these respiratory infections.
急性呼吸道感染（ARI）和严重急性呼吸道疾病（SARI）是全球范围内的公共卫生负担。在前往印度安达曼和尼科巴群岛的卡尔尼科巴岛的医院就诊的患有 ARI 和 SARI 的患者中，非 SARS-CoV-2 呼吸道病毒的比例尚未记录。全球范围内都有报道称，在 COVID-19 大流行期间，其他呼吸道病毒的流行病学发生了变化。
在印度卡尔尼科巴岛的 BJR 医院的住院和门诊环境中，对尼科巴部落成员进行了ARI 和 SARI 的前瞻性监测。2019 年 6 月至 2021 年 5 月期间，在 BJR 医院登记了患有 ARI 和 SARI 的患者。在浦那的 ICMR-NIV，使用双重 RT-PCR 检测法来检测呼吸道病毒的存在。通过比较大流行期间和大流行前期间的病毒流行率，来衡量非 SARS-CoV-2 呼吸道病毒的流行率。
在 COVID-19 大流行期间，甲型流感（H3N2）和鼻病毒是主要报告的非 SARS-CoV-2 呼吸道病毒，而人类偏肺病毒和甲型流感（H1N1）pdm09 在大流行前期间是最常报告的病毒。这一结果表明，在大流行期间，非 SARS-CoV-2 的循环发生了变化。
相当一部分呼吸道感染与呼吸道病毒有关。与大流行前时期相比，在卡尔尼科巴岛，非 SARS-CoV-2 呼吸道病毒的感染率在大流行期间较高。这项研究揭示了在当地的尼科巴部落中，其他呼吸道病毒的循环发生了变化。临床医生和相关医疗人员应该更加警惕这些呼吸道感染。
