Climate and weather, thus, have the capacity for large-scale impact on the emergence and spread of infectious diseases. In one example, these elements directly affect human lifestyle and behaviors, like increasing time spent outdoors during long, hot summer days, thus, heightening their exposure to vector-borne diseases.
