A new generation of real-time environmental monitoring systems to study the impact of El Niño on disease dynamics.

Global warming is drastically altering weather patterns, accentuating the frequency and strength of global events such as the El Niño Southern Oscillation. This alteration is driving the spread of diseases sensitive to climate such as diarrheal diseases. Environmental monitoring through remote sensing, in combination with data from epidemiological surveillance programs, is facilitating the study of infectious disease dynamics associated with El Niño. This integrative approach can inform the development of strategies for mitigating the impact of these diseases on public health. Here, we discuss some of the achievements of this approach in the management, control, and prevention of infectious diseases linked to El Niño.
