Answer: Microbes can spread and pass diseases in a number of ways:
1) By direct contact: physical contact (touching etc) with an infected person; sexually-transmitted diseases are passed on this way.
2) By indirect contact: touching something which an infected person has touched eg a towel, door knob, cup etc.
3) By inhalation: breathing in droplets containing microbes which have been produced by sneezing or coughing eg flu, TB, pneumonia.
4) By contaminated food or drink: eating food or drinking water which has been infected by microbes eg typhoid, cholera.
5) By animal vectors: animals can pass microbes on to humans by biting them eg fleas, mosquitoes.

Answer: A disease that cannot be spread is also known as a non-infectious disease. This is a disease that may be caused by the environment (e.g. skin cancer from radiation from the Sun), or lack of food (e.g. scurvy from lack of Vitamin C), genetic disorders, or any source other than an infection. They can also be caused by drugs and carcinogens (cancer-causing agents).
Non-infectious diseases cannot be spread from person to person as in infectious disease, but can be passed down genetically in some cases. It is important to note that non-infectious diseases are not caused by bacteria, viruses, fungi or parasites; diseases caused by these organisms are infectious diseases.
Answer: yes, of course. diseases spread by interaction with other people. lets say someone was sick, they touch a door nob, you touch the door nob after them, you now have the disease(it could be just the common cold). you should wash your hands often, try not to touch things, if someone near you is sick.
Answer: The main spread of mad cow disease actually came from a sheep. Some bits of sheep meat was used in cow feed until the 2000`s. Sadly, part of the sheep`s brain was in the meat and in their brain tissue was scrapie. A disease were an efected prion(pronounced pree-on) a diseased protein particle eats part of a sheep`s brain, therefore cattle got the disease. When cattle was shipped to other countries just like the black plague, it spread, but luckily it was only a huge risk temporarily.
Answer: The spread of diseases can be prevented through the use of properhygiene. Another way to prevent the spread is to encourage infectedpersons to stay away from social situations where they might infectothers.
Answer: The ways most religions spread is through curiosity and movement. As in people who practiced the religion moved to a new country and set up a church for that religion saying that your life will be btter if you practice it. Imagine going to practice a new religion and you said oh my life has gotten better from doing this, ill go and tell my neighbor about it.
