Predicting pandemics: What cholera has taught us about COVID-19



Significant advances in technology have brought new discoveries - from the outer reaches of space, where remote sensing monitors on satellites circle the earth, to the ultramicroscopic through application of next generation sequencing and informatics that can be applied to public health. Vibrio cholerae is a useful example of a fundamental linkage of human health to the environment, namely the oceans.  The causative agent of cholera, Vibrio cholerae is associated with major epidemics yet it is an aquatic bacterium with a versatile genetics and is distributed globally in bodies of water, notably estuaries, throughout the world.  Vibrio species, both nonpathogenic and those pathogenic for humans, marine animals, or marine vegetation, play a fundamental role in nutrient cycling hence cannot be eradicated. They have also been shown to respond to warming of the surface waters of the world oceans, with increase in their numbers correlated with increased incident of infections in humans  The cholera prediction model has been successfully modified for COVID-19 and is now being extended to other infectious diseases including Dengue.  Other species of Vibrio have been shown to cause disease and, with climate change, the incidence of vibriosis has increased significantly around the world and, in the U.S., from Florida to New England, including Maryland. In summary, microorganisms in the environment can serve as a critical indicator of human health and wellness, with the ubiquitous vibrios in the world oceans offering a model system for public health.
