Causes of Zoonotic Diseases
Zoonotic Diseases can be caused by a virus, bacteria, parasites, or fungus in the animals. These germs can be spread through direct contact i.e. petting them or farming them or through indirect contact through food, and water, the major causes of zoonotic diseases are:
- Food and water contamination: Contaminated food and water supply is one of the major causes of zoonotic diseases. Drinking unpasteurized milk, eating undercooked or raw meat, eggs, etc. can lead to several stomach related infections. Eating fruits and vegetables infected with animal faeces is also one of the causes for infection and thus, should always be looked out for.
- Direct contact with animals: If you have pets, you are more prone to infections like rabies, ringworm, etc. Farmers primarily come in direct contact with several animals like horses, donkeys, cattle, birds, etc. and are at a risk of Glanders, bird flu, clamydiosis, and more. An animal can cause you an infection even when it appears healthy. Therefore, it is crucial to get them vaccinated at regular intervals to get rid of any potential risks.

Animal habitats, aquarium tank water, pet food and water dishes, plants, etc. that may carry a lot of bacteria. Thus, these things to be handled with care with appropriate safety measures in place.

- Hunting: People who like hunting and eating bush meat, can contract various infection including HIV due to improper handling of the meat and not cleaning the meat properly.
Common Zoonotic Diseases
In the recent past, one of the zoonotic diseases that has claimed the lives of many is the monkey pox. A bit similar to the small pox that we see obliterated today, it can come to humans from monkeys – either by touch or any physical contact.
However, that is not the only common zoonotic disease that you need to be aware of. As you shall see below, most of these diseases are quite deadly in nature.
Some common zoonotic diseases include:
Rabies is spread through the bite of an infected animal to a healthy one. It infects the nervous system and can have symptoms like paranoia, fits of rage, etc. This disease is fatal and should be prevented with vaccination as once the symptoms start too show, it can’t be treated
Ebola is a viral haemorrhagic fever that has killed over 50 percent of the affected individuals. The virus’ signs include high fever, muscular pain, sore throat, etc.
The virus subsequently decreases the function of livers and kidneys and can eventually lead to death due to internal bleeding. It is spread through contact with the body fluids or blood of the infected animal/individual.
3. Monkey Pox:
Monkey pox virus is transmitted through animal bite or coming in direct contact with the blood of an infected monkey. It can spread from both animals to humans and humans to humans.
The symptoms include swelling of lymph nodes, muscular pain, etc. The virus should be recognized early on and is very difficult to treat.
4. Diarrheal Diseases
Eating contaminated food or drinking water filled with animal saliva can cause a lot of stomach related infections, and diarrheal diseases. However, depending on their type, they can be treated and aren’t fatal in nature.
