The first manifestation of a viral infection may be conjunctivitis. There are limited data on the etiology of viral conjunctivitis in Vanuatu, a country in the South Pacific Ocean. Patients presenting to one of two Vanuatu health centers with presumed infectious conjunctivitis were eligible if symptom onset was within 14 days of screening. Conjunctival and anterior nasal swabs were obtained and subjected to unbiased RNA deep sequencing (RNA-seq) to identify DNA and RNA viruses. For samples collected from May to November 2021, RNA-seq identified a viral etiology in 12/48 patients. Human adenovirus species were the most common viruses (58%) detected, followed by human herpes viruses (cytomegalovirus, varicella zoster virus, and human herpes 7 virus). Rhinovirus C, Epstein-Barr virus, and bocavirus were also detected. In summary, the etiology for viral conjunctivitis in Vanuatu appears broad. Unbiased testing may be useful for disease surveillance.
病毒感染的最初表现可能是结膜炎。南太平洋岛国瓦努阿图的病毒性结膜炎病因学数据有限。如果症状在筛查后 14 天内出现,在两个瓦努阿图卫生中心之一就诊的疑似传染性结膜炎患者符合入选条件。采集结膜和前鼻拭子,并进行无偏 RNA 深度测序(RNA-seq)以鉴定 DNA 和 RNA 病毒。对于 2021 年 5 月至 11 月采集的样本,RNA-seq 在 48 例患者中的 12 例中确定了病毒病因。检测到的最常见病毒是人腺病毒属(58%),其次是人类疱疹病毒(巨细胞病毒、水痘带状疱疹病毒和人类疱疹病毒 7 型)。也检测到了鼻病毒 C、EB 病毒和博卡病毒。总之,瓦努阿图病毒性结膜炎的病因似乎很广泛。无偏检测可能对疾病监测有用。
