5 diseases from animals

There are 5 deadly disease that come from animals. One of them was from gorillas and it was called the crabs. Another one was an insane mind parasite. The parasite infected the brains of more than half the human population. This is including about 50 million Americans. It is thought to increase the risk of neuroticism and may cause schizophrenia. Its primary host is house cats. You can get it from cat feces. Symptoms in humans are like a flu. This bug never goes away. Some scientists think it has change human behavior enough to shape entire cultures. A third one is HIV/AIDS. HIV is the virus that causes AIDS. It came from chimps and other primates. It was thought to have first infected humans at least a century ago. At the end of 2007, there was about 33 million people had HIV. This is including about 2.7 million new cases for the year. There is about 2 million that die. Two thirds of HIV infections are in Saharan Africa. The fourth one is the black death. This disease was carried from rodents. The Yersinia Pestis lived on the rodent and had the disease. That's how it spread and killed millions of people. The last one is swine flu. Swine can also be said as influenza oandemic. The 1918 influenza pandemic went through the world within months. This disease killed about 50 million people. This was more than any other illness in recorded history. One-fifth of the world's population was infected. It struck more than 25 percent of U.S. residents. I learned this today.
