雨水收集作为一种可替代的饮用水来源，在世界范围内受到越来越多的关注。虽然收集的雨水通常在没有任何消毒的情况下被消耗，但这种类型的水源的微生物质量可能很差。在世界各地，收集和储存雨水的消费者可能面临各种传染病的相当大的风险。本文综述了将特定疾病风险归因于饮用受污染雨水的研究。由于饮用未经处理的雨水而导致的疾病包括沙门氏菌和弯曲杆菌引起的细菌性腹泻，军团菌引起的细菌性肺炎，梭状芽胞杆菌引起的肉毒中毒，组织蠕虫以及贾第鞭毛虫和隐孢子虫引起的原生动物腹泻。简单的指标系统，如粪便大肠菌群测量，可能不足以确定与雨水收集系统用水有关的微生物风险。
Rainwater harvesting is receiving increased attention worldwide as an alternative source of drinking water. Although collected rainwater is typically consumed without any type of disinfection, the microbial quality of this type of water source can be poor. Around the world, consumers of collected and stored rainwater may be at considerable risk to a variety of infectious diseases. This review presents studies attributing specific risks of diseases to the consumption of contaminated rainwater. Diseases attributed to the consumption of untreated rainwater include bacterial diarrheas due to Salmonella and Campylobacter, bacterial pneumonia due to Legionella, botulism due to Clostridium, tissue helminths, and protozoal diarrheas from Giardia and Cryptosporidium. Simple indicator systems such as fecal coliform measurements may prove to be inadequate for determining microbial risks associated with consumption of water from rainwater catchment systems.
