Legionnaires' disease Legionnaires' disease Legionnaires' disease, also known as legionellosis, is a form of atypical pneumonia caused by any type of "Legionella" bacteria. Signs and symptoms include cough, shortness of breath, high fever, muscle pains, and headaches. Nausea, vomiting, and diarrhea may also occur. This often begins 2-10 days after exposure. The bacterium is found naturally in fresh water. It can contaminate hot water tanks, hot tubs, and cooling towers of large air conditioners. It is usually spread by breathing in mist that contains the bacteria. It can also occur when contaminated water is aspirated. It typically does not spread directly between
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
