预测霍乱这种与水有关的疾病的发生的能力提供了一个重大的公共卫生优势。基于卫星的叶绿素（浮游生物丰度的替代物）估计值与霍乱发病率有关。然而，霍乱菌可以在各种沿海生态条件下生存，因此限制了叶绿素的预测能力，因为它只能提供海水绿色的估计。在这里，提出了一个新的遥感指数：卫星水标志（SWM），估计沿海水域的条件，根据观察到的变化之间的差异蓝色（412 nm）和绿色（555 nm）波长，可以与季节性霍乱发病率。对于相对清澈（蓝色）和浑浊（绿色）的水，该指数被限制在物理上可分离的波长之间。使用SWM，预测霍乱与合理的准确性，至少提前两个月，可以在流行的沿海地区实现。
The ability to predict an occurrence of cholera, a water-related disease, offers a significant public health advantage. Satellite based estimates of chlorophyll, a surrogate for plankton abundance, have been linked to cholera incidence. However, cholera bacteria can survive under a variety of coastal ecological conditions, thus constraining the predictive ability of the chlorophyll, since it provides only an estimate of greenness of seawater. Here, a new remote sensing based index is proposed: Satellite Water Marker (SWM), which estimates condition of coastal water, based on observed variability in the difference between blue (412 nm) and green (555 nm) wavelengths that can be related to seasonal cholera incidence. The index is bounded between physically separable wavelengths for relatively clear (blue) and turbid (green) water. Using SWM, prediction of cholera with reasonable accuracy, with at least two month in advance, can potentially be achieved in the endemic coastal regions.
