Though not many diseases suffered by animals spread to humans, there are some exceptions of zoonotic diseases with deadly outcomes. Rats, rabbits, cats, dogs and even snakes carry diseases that can prove to be deadly to humans. Some of these diseases were known to mankind for ages whereas some of them were diagnosed only in recent years. Many confuse malaria to be a zoonotic disease though it is not. Diseases from animal can spread to humans through infected animal bites, bug that have bitten infected animals, coming in contact with animal feces or directly from the animal itself. Here is the list of top 6 diseases that spread from animals.

Anthrax is a life-threatening deadly disease that is transmitted to humans through ruminants like cattle, sheep, goats or horses.

In recent years, the possibility of using the anthrax causing bacterium, Bacillus Anthracis in biological warfare, has caused a lot of concern among many targeted nations. The anthrax organism is known to exist in the soil in the form of spores for nearly 48 years, which makes it difficult to eradicate this disease. Though anthrax can transmit through skin and ingestion, the most deadly infection is caused by inhaling the spores.
