Water heating by a domestic water heater. Two conflicting safety issues affect water heater temperature—the risk of scalding from excessively hot water greater than , and the risk of incubating bacteria colonies, particularly "Legionella", in water that is not hot enough to kill them. Both risks are potentially life-threatening and are balanced by setting the water heater's thermostat to . The European Guidelines for Control and Prevention of Travel Associated Legionnaires’ Disease recommend that hot water should be stored at and distributed so that a temperature of at least and preferably is achieved within one minute at points of use.

Epizootic hemorrhagic disease virus "Culicoides" gnats ("C. verripennis") and cannot be transmitted directly from deer to deer. EHDV manifests itself as epizootic hemorrhagic disease (EHD), which has similar symptoms to adenovirus hemorrhagic disease (AHD), “bluetongue” disease, and malignant catarrhal fever. Instead of being spread by a vector like EHDV, AHD is spread from animal to animal by direct contact and bodily fluids. EHDV is also antigenically different from “bluetongue” disease but the clinical signs of each disease are very similar. EHDV causes deer to lose their fear of humans and causes weakness, excessive salivation, bloody diarrhea, fever, rapid pulse and rapid respiration rate. Hemorrhage
