A pungent smell hangs in the early morning air as researchers collect samples of sewage dumped into a river in Nepal － a cost-effective way to trace the coronavirus spread for the resource-strapped Himalayan nation.

研究人員在尼泊爾一條河流採取排放到河中的污水樣本，空氣中飄著一股強烈的臭味—對於這個資源拮据的喜馬拉雅山國家來說，這是追蹤冠狀病毒散播情況的一種划算方式。

"When you are limited in the resources that are available for testing and screening, this is a quick and easy way － and a cheaper way － of finding hotspots," said Dibesh Karmacharya, who co-founded Center for Molecular Dynamics Nepal, the NGO leading the research.

「當你篩檢所需資源有限，這是找出熱點的便捷方法，而且比較便宜」，率領這項研究的非政府組織「尼泊爾分子動態中心」共同創辦人卡瑪查亞說。

由於有些感染病例是無症狀，這種檢測方式涵蓋全社區，而非針對個人，有助於在疫情或許尚未浮現的地方得知病毒蹤跡。（法新社）
