Germ Theory

Racing through the room, faster than a bullet, is your brother’s sneeze. It contains something deadly; something called a virus. A virus is an infectious agent that typically consists of a nucleic acid molecule in a protein coat. It is too small to be seen by anything but a powerful microscope, and is able to multiply only within the living cells of a host: "a virus infection" is what that's called. If you read that definition twelve times and still don’t understand what a virus it, hopefully this will help you understand it: a virus is a micro-organism that can infect our bodies, and make us sick. They have certain parts that make it work properly. It can only survive if it is living inside of a body. It is the cause of having a fever in bed with a garbage can overflowing with tissues. What if the virus goes into someone else? According to Flu Attack, the virus is covered with tiny yellow keys. If these tiny keys fit perfectly into purple “locks” on the outside of the cell, the virus will be given permission to enter safely by the “guard”. Once it enters, the "welcoming committee" surrounds the virus, hugging it. These pieces fly off and the virus capsule explodes. The guards were fooled into letting the bad virus right into the nucleus, or the head of the cell. The virus is immediately seen by the “copy machine” molecule, and it begins to copy the virus. Those viruses leave the cell and spread to another cell, and another, and another. But don’t worry. Your white blood cells will track them down before they empower your body. A long time before. You have a lot of viruses, yes, but you have way more cells.

These are some simulation viruses and bacteria.

How can you prevent disease, you may ask?  There are many ways to get sick, so there are also many ways to prevent illnesses. According to Scientific Physic, some ways to prohibit diseases from entering your body include…

  • Washing your hands before and after eating and cooking, and touching things in public places

  • Not touching your face if your hands are not clean

  • keeping places where food is being prepared clean and washing them properly

  • Completely cooking food such as meat or seafood

  • Drinking clean and pure water only

  • Refrigerating food if it is meant to be kept cool

  • Making sure cooked food doesn't sit out for too long

  • Washing fruits and vegetables before eating to prevent contamination.

  • Making sure the food you eat is not spoiled

  • Making sure that the air you breathe is clean

  • Using window screens, insect repellent, and mosquito netting to prevent bites from insects

  • Not walking barefoot on soil, in public places, or swimming in contaminated water

  • Brushing and flossing teeth daily to avoid getting gum diseases

  • Avoiding touching any bodily fluids from a sick person. In fact, don’t touch them if you can help it.
