Preventing Infectioius Diseases
Five Agents 1. Bacteria- Tiny single celled organisms that can cause diseases. Most bacteria are harmless, in fact some is helpful. Some bacteria cause illness when they grow on or in your body. 2. Virusesdisease causing
particles made up of a gene strand and a protein coat. Reproduce by taking control of the living cell and making it make more viruses. 3. Fungiabsorb the nutrients of living or dead organisms. Athleteâ€™s foot is an example
4. ProtistsLarger, more complex than bacteria. Some account for diseases. E.g. Malaria 5. Parasites get energy by feeding off of other living things. Lice, tapeworms, and roundworms are examples
Infectious Diseases Spread Person to Person- Sneezing, coughing, kissing, drinking from the same glass and sexual contact are all ways that people can spread disease from one person to the next.

Mucous Membranes- Forms a barrier much like skin to stop the bacteria from entering. This barrier often traps the bacteria and keeps it from entering the body Chemicals- Many of the chemicals in your body destroy pathogens. Sweat is acidic and prevents the growth of bacteria. Your stomach also creates acid to kill bacteria.

Immune system- A system made up of special blood cells and antibodies that fight the intruders. They travel through the lymphatic system. This system carries things to your lymph nodes where white blood cells are stored.
are a reaction from your body. Stay home Drink water Follow doctorâ€™s directions Wash hands
