What animal disease is transmissible to humans?

Avian influenza, particularly the H1N1 strain, is a zoonotic disease, meaning it can be transmitted from animals to humans. This type of influenza primarily affects birds, but certain strains, including H1N1, have shown the ability to infect humans, usually after close contact with infected birds or contaminated environments. Symptoms in humans can range from mild respiratory issues to severe pneumonia and even death, depending on the strain and health of the individual.

In contrast, dog flu is an illness found primarily in dogs and does not typically transmit to humans. Measles is a highly contagious viral disease that spreads among humans and has no link to animal transmission. Mesothelioma, on the other hand, is a type of cancer that is associated with asbestos exposure and is not a transmissible disease at all, either between humans or from animals to humans. Thus, the accurate answer showcasing an animal disease that can be transmitted to humans is indeed avian influenza (H1N1).
