In most of the cases the infections occur at farms and markets. The reason for this is that the pathogens are able to switch various genes and to be prepared to attack their hosts. The hosts can be both the humans and other species as well. There are also different methods of being infected by an animal. Some simple and apparently innocent actions can be deadly. For example simply allowing a performance monkey get on your head might infect you with different microbes.
The microbes might enter your system, mutate and then destroy your body. In most of the cases, the human body is not prepared for these viruses because they are not in their normal form. They are mutated, and as a result, they are much more resistant to different treatments. These diseases which are passed from the animals to humans are called zoonoses. More than 35 zoonoses can be caught simply by touching the animals, and almost 50 can be caught by being bitten by the animal. The animals can also carry viruses which can infect the animals and kill them as well, the process is mutual.
These are the top 10 diseases which can affect different species. The first disease which can affect various species, are the “crabs”, or the pubic lice. It is believed that the humans caught the crabs from the gorillas, by sleeping in their nests, or by eating the gorillas. The humans are the only primates who have both head and pubic lice. The gorillas have the pubic lice, whereas the chimps have the head lice only. There are many respiratory diseases which are responsible for killing people. The respiratory syncytial virus (HRSV) and human metapneumovirus (HMPV) are the most common of its kind. These viruses have affected the people for a long time now, and as a result, we have become immune to them. The chimps however have a weaker immunity, and as a result between 1999 and 2006, entire populations of chimps have been killed by these viruses.
It can be pretty difficult to study the populations of the wild animals. However, the scientists still do it regardless of the risks associated with this activity. They have discovered that the humans have transmitted polio to the chimps at Gombe Stream National Park in Tanzania. It is also believed that the chimps from that area have also developed yaws, which is a disease similar to syphilis. This disease is not sexually transmitted as syphilis is. The chimpanzees and the gorillas from different regions of the world have been infected by anthrax. Once again, it is believed that the humans are the ones responsible for transmitting the disease to the animals, through the infected cattle which they have herded in zones populated by these primates. Ebola is a very dangerous disease which was first seen in primates such as gorillas and chimpanzees. The disease can also attack the humans, and it is believed that the humans first contracted it when they consumed the meat of the animals infected by it.
The disease is now transmittable from human to human through the blood or bodily fluids. It has killed thousands of people over the course of history and it is the most common in the regions from Africa. This disease has very awful symptoms including diarrhea, fever, muscle pain, headaches, sore throats, vomiting. The person then experiences both internal and external bleeding, and it is deadly in 25 and 90 percent of the cases. Another common illness which is present in both the animals and the humans is the ulcer. We gave the tigers the bacteria associated with this disease. The disease was then transmitted to the lions, cheetahs, and many other felines.
The cats also gave us a disease, more precisely the Toxoplasma gondii, a parasite which infects the brains of more than half of the entire population of the world. This parasite may lead to schizophrenia and other similar illnesses. The symptoms are similar to the flu ones, but this disease can not be cured. The people who have this disease are more neurotic than the ones who are not affected by it. One of the most popular and most dangerous viruses in the world is common in both animals and humans. The HIV/AIDS first originated in the chimps and other primates as well. It is said that the humans first contracted the disease almost one hundred years ago. This disease completely destroys the immune system and as a result, any illness can be deadly. It is said that 33 millions of people have had HIV, and about 2 million people die from it each year. Two-thirds of the people who are infected with this deadly disease are from Africa.
There are many diseases which are transmitted through biting, and one of the most common of this kind is malaria. About 50 million people are infected each year with malaria in Africa, and 350 million all over the world. It is said that 2.5 percent of those people die from it each year. The bubonic plague is one of the most famous diseases which are common in different species. The Black Plague has caused the death of more than 75 millions of people. It can be carried by various animals including rodents, and cats, but are the deadliest when they are transmitted from humans to humans. The number one disease which can affect both humans and animals is the influenza virus. The 1918 flu killed 50 million people and it attacks us each year. The most recent one was the swine flu and vaccine for it hasn’t been developed a yet.11
