Major human epidemic viruses include Influenza, Human Immunodeficiancy Virus (HIV), Measles, and Rubella. Smallpox has been eradicated as a major epidemic virus, however emerging viruses and engineered viruses pose a significant challenge for the future. HIV is no longer considered an emerging virus as it was discovered over 20 years ago, and it has grown to become a major epidemic. Other emerging viruses include Severe Acute Respiratory Syndrome (SARS), henipaviruses and Ebola which have been contained through aggressive contact tracing and isolation of patients and suspected carriers of the disease.
Hoof (UK Foot) and mouth disease is a major animal epidemic virus affecting the agricultural industry of any country with an outbreak. It affects cows, pigs, sheep, goats, deer and other cloven hoofed animals.
