Veterinary infectious diseases focus on illnesses that affect domestic animals, livestock, and wildlife, many of which can also pose threats to human health. These diseases are caused by a wide range of pathogens including bacteria, viruses, fungi, and parasites. Effective management and diagnosis are essential to protect animal welfare, ensure food safety, and prevent economic losses in the agricultural sector. With the growing interaction between humans and animals, the study of veterinary infectious diseases plays a crucial role in controlling zoonotic infections. Surveillance, vaccination programs, improved diagnostics, and biosecurity measures all contribute to preventing outbreaks.
