What are the zoons?

Zooses are diseases that can transmit animals to humans. They can be caused by bacteria, viruses, parasites or fungi and can be transmitted by food, environment or direct contact with the animal. As the human population increases and more world is used to produce food, contact with wild animals grows and zoonotic diseases can become more common. Air travel and crowded housing in cities help zoonos to spread as soon as they are infected. While some zoonosy, such as rabies, may be fatal, others cause milder diseases and many zoonos may not cause any symptoms in animals that carry them. Rabies is an infectious disease caused by a virus. It is usually transmitted by people by biting or scratching from an infected dog and is usually deadly if it is not treated. Symptoms of similar influenza progress until the infected person is paralyzed, the coma falling and dying. This disease can be prevented or successfully treated before developing symptoms by cleaning the original blowy and administration of rabbin vaccines.

Cat scratch fever is zoonosis caused by bacteria and is transmitted to people through scratches or bite of cats. Initially, a rash is produced around the infection site, followed by swelling of the nearby glands or lymph nodes. Sometimes infected people can experience a fever and feel good, but many have no symptoms. The disease usually disappears in itself, although it may be more serious in children. Fever scratches the cat can be treated with antibiotics.

zoonoses known as pig flu and bird flu causes forms of influenza that have the potential to become life -threatening in humans. Pluto flu can be handed over from pigs to man and also from man to man. Bird flu cannot be transmitted among people and one becomes onlyinfected by direct contact with birds. Both diseases have symptoms that are similar to human influenza such as sore throat, fever and muscle pain butComplications such as pneumonia may occur and may cause death in some cases. Antiviral drugs are available to treat bird flu and pig flu.

Maybe one of the most famous Zoonos, plague or black death, has smoked millions of people during the Middle Ages. This disease is caused by bacteria that infect rodents and fleas that infest them. One acquires the disease after being bitten by infected fleas. Symptoms usually affect the lungs, liver and spleen, and if antibiotics are not treated, the disease progresses into pneumonia, which is often fatal.
