世界卫生组织估计，2016 年全球霍乱大流行造成的负担为每年 1.3 至 400 万例，病死率从 2015 年的 0.8% 翻一番，达到 2016 年的 1.8%。霍乱是由霍乱弧菌引起的，这种细菌存在于环境储存库中，以游离浮游形式或与宿主共存。有机体、非生命颗粒物或沉积物中，并参与各种生物地球化学循环。越来越多的流行病学研究正在利用陆基和水基遥感观测来监测、监测或绘制弧菌病原体和霍乱疫情的风险图。尽管卫星传感器无法直接感知弧菌病原体，但可以利用遥感数据来推断它们的存在。在这里，我们回顾了海洋颜色遥感数据的使用，结合病原体的生态信息，绘制其分布图并预测疾病发生的风险。最后，我们评估了基于卫星的霍乱信息如何帮助支持健康（目标 3）、水质（目标 6）、气候（目标 13）和水下生物（目标 14）的可持续发展目标和具体目标。
The World Health Organization has estimated the burden of the on-going pandemic of cholera at 1.3 to 4 million cases per year worldwide in 2016, and a doubling of case-fatality-rate to 1.8% in 2016 from 0.8% in 2015. The disease cholera is caused by the bacterium Vibrio cholerae that can be found in environmental reservoirs, living either in free planktonic form or in association with host organisms, non-living particulate matter or in the sediment, and participating in various biogeochemical cycles. An increasing number of epidemiological studies are using land- and water-based remote-sensing observations for monitoring, surveillance, or risk mapping of Vibrio pathogens and cholera outbreaks. Although the Vibrio pathogens cannot be sensed directly by satellite sensors, remotely-sensed data can be used to infer their presence. Here, we review the use of ocean-color remote-sensing data, in conjunction with information on the ecology of the pathogen, to map its distribution and forecast risk of disease occurrence. Finally, we assess how satellite-based information on cholera may help support the Sustainable Development Goals and targets on Health (Goal 3), Water Quality (Goal 6), Climate (Goal 13), and Life Below Water (Goal 14).
