背景:儿童呼吸道病毒性疾病是发展中国家发病率和死亡率的主要原因。这项研究的目的是了解Nicobarese部落中呼吸道病毒的季节性模式和激增。
方法:从在CarNicobarIsland的BJR地区医院就诊的ARI和SARI病例中收集呼吸道标本,印度,2021年至2022年。通过使用qRT-PCR测定从样本中鉴定呼吸道病毒。使用MicrosoftExcel和SPSS21收集并评估气象参数。评估了呼吸道病毒的激增与每个气候参数之间的显着关联。
结果:在这项以医院为基础的横断面研究中,纳入了471例ILI病例,其中209例呼吸道病毒感染呈阳性。在这些呼吸道病毒感染中,201例(96.2%)感染单一呼吸道病毒感染,8人(3.8%)患有混合病毒感染。发烧,咳嗽,在这些土著居民中,寒战是呼吸道疾病最常见的症状。呼吸道病毒与儿童(5岁以下和6至15岁)的流感样疾病之间存在显着联系。
结论:这项患病率研究表明,儿童比成人更常见病毒性呼吸道感染。在这些呼吸道病毒中,呼吸道合胞病毒A(RSV)和乙型流感病毒主要在5岁以下的部落儿童中报告.在2021年,这些病毒在冬季频繁记录。高湿度等气候因素,高降水,温度适中,适度降雨与呼吸道病毒感染有关。这项研究暗示了预防CarNicobar岛进一步爆发呼吸道病毒感染的重要信息。
BACKGROUND: Respiratory viral illnesses among children are a prominent cause of morbidity and mortality in the developing world. The aim of this study is to understand the seasonal pattern and surge of respiratory
viruses among the Nicobarese tribe.
METHODS: Respiratory specimens were collected from both ARI and SARI cases attended the BJR district hospital in Car Nicobar Island, India, between 2021 and 2022. Respiratory
viruses were identified from the specimens by using the qRT-PCR assay. Meteorological parameters were collected and evaluated using Microsoft Excel and SPSS 21. The significant association between the surge of respiratory
viruses and each climatic parameter was evaluated.
RESULTS: In this hospital-based cross-sectional study, 471 ILI cases were enrolled, and 209 of these were positive for respiratory viral infections. Of these respiratory virus infections, 201 (96.2%) were infected with a single respiratory virus infection, and 8 (3.8%) had mixed viral infections. Fever, cough, and chills were the most common symptoms of respiratory illness among this indigenous population. There was a significant link between respiratory
viruses and influenza-like illness in children (below 5 years and 6 to 15 years).
CONCLUSIONS: This prevalence study revealed that viral respiratory infections were more common in children than adults. Among these respiratory viruses, respiratory syncytial virus A (RSV) and influenza B virus were predominantly reported among tribal children up to age five years. In the year 2021, these
viruses were recorded frequently during the winter season. Climate factors such as high humidity, high precipitation, moderate temperature, and moderate rainfall are found to be correlated with respiratory viral infections. This study implicates important information for preventing a further outbreak of respiratory viral infections in Car Nicobar Island.
