Many deadly diseases present in human nature. want to know? The disease sometimes move from human to animal or from animal to human.
Bacteria and viruses are very simple creatures multiply and the disease it causes highly contagious. Currently a number of contagious and deadly disease has been transferred from animals to humans and from humans to animals. What are the deadly disease?
Cross-species infection could come from farms or markets, where conditions create a mixing pathogens. Which gives pathogens the opportunity to exchange genes and equipment up to a previous killing of foreign host.
Transmission can also occur from activities that seem trivial and harmless, like letting a monkey riding on top of your head, a lot happens on the streets in Bali.
Microbes from the two varieties can even be assembled in your intestines, the virus evolved and make some 'dancing' to turn you into a host of infectious and deadly.
Infectious diseases from animals to humans is called zoonosis. There are more than three dozen diseases, whether transmitted through touch as well as from the bite.
As quoted from the LiveScience, Saturday (15/05/2010), the following 10 deadly infectious disease from cross-species:
1. Influenza pandemics
Deadly flu pandemic like the Spanish flu, swine flu or bird flu has struck in several countries. Potential pandemic is very easily spread by direct contact, so that could be very dangerous.
Between 1918 and 1919, Spanish flu killed 20 to 40 million people. This is truly a global disaster. This deadly flu attacked people ages 20 to 40 years, and infects 28 percent of Americans.
And lately also emerging swine flu and avian influenza that has become epidemic in some countries. Now, governments are better prepared, scientifically and logistics to manage the outbreak. However, there is no vaccine against swine flu.
2. Plague
Pestilence known as 'Black Death', is an infectious disease caused by the bacterium Yersinia pesti, most often carried by rodents and fleas. At mid-century, millions of people across Europe died from plague caused by rat fleas that there are many homes and offices.
3. Diseases due to bites
Zoonotic diseases are expected to increase due to the bite of an animal that kills hundreds of thousands of people every year. Mosquitoes are the main causes, such as dengue fever and malaria.
There were also outbreaks of disease caused by insect bites, rabies due to dog bites and other wild animals.
4. HIV/AIDS diseases
HIV, the virus that causes AIDS, originated from chimpanzees and other primates and the first human infection is estimated at least a century ago. The virus is damaging the immune system, opening the door to a host of deadly infections or cancer.
5. Cat brain parasite that is transmitted to humans
Weird parasite Toxoplasma gondii infects the brain more than half the human population, including about 50 million Americans. Estimated to increase the risk of neuroticism and can cause schizophrenia. The main cause is the cat's house, which is the sexual reproduction of microbes. This usually comes from cat feces.
6. Humans give cats the bacteria that cause stomach ulcers
Cats have been transmitted bacterium that causes peptic ulcers, Helicobacter pylori, an ancestor of mankind since thousands of years ago. And according to scientists, this disease is now spreading to other animals such as lions, zebras, and tigers.
7. Gorillas gave humans pubic lice crabs
Humans get pubic lice from gorillas about 3 million years ago. This disease is not transmitted through sexual contact with a gorilla, but with overnight stay or dining in gorilla nests. The scientists named the disease in the year 2007 'crab'.
