What causes rinderpest in animals?
Rinderpest was caused by a paramyxovirus (genus Morbillivirus) closely related to those that cause measles in humans and viral distemper in dogs. The virus was transmitted by close direct or indirect contact. After an incubation period of three to nine days, fever and loss of appetite occurred in an infected animal.
Who spread rinderpest?
Rinderpest is spread between animals by direct contact. The virus can be in secretions from the eyes, nose, or mouth, and the feces, urine, blood, milk, or reproductive fluids of infected animals. The virus may also be spread by fomites such as contaminated equipment, feed troughs and watering tanks.

An epizootic is defined as an outbreak of disease in which there is an unusually large number of cases, whereas an enzootic refers to a low level of disease that is constantly present in a population (Steinhaus, 1967; Onstad et al., 2006). The study of epizootiology crosses multiple interests within insect pathology.

Why did the smallpox vaccine leave a round scar?
Why did scarring occur? Scars of the smallpox vaccine are usually a result of the human body’s healing process. What happens is, when the skin is punctured, the body’s immune system responds and repairs the punctured tissues. Based on the skin cells’ different arrangement, the skin area tends to show a scar.
