Swamp fever is a term commonly used to describe a disease that affects horses, known medically as Equine Infectious Anemia (EIA). This viral disease is primarily transmitted through the bites of infected horse flies and can cause various symptoms ranging from fever, anemia, and fatigue to more severe complications such as organ failure and death. Due to the severity and contagious nature of swamp fever, there are several different names used to describe the same disease. For example, it is also known as horse AIDS, equine malaria, or mountain fever. While these synonyms may sound daunting, it is important for horse owners to understand the symptoms and potential risks associated with this disease to ensure the health and safety of their equine companions.
