Concept How to treat/prevent diseases.

Bacterial Diseases 1.Rabies – transmitted through bite of infected animal. 2.Lyme disease – bull’s eye rash; tick bite.

Bacterial Diseases 3. Bacterial Meningitis – inflammation of nervous system. 4. Leprosy – skin lesions or blisters.

Viral Diseases 1.AIDS/HIV – immune system deficiency; more likely to get other infections. 2.Influenza – infection of nose, throat, lungs. 3.Common Cold – runny nose, sore throat, headache. 4.Chicken Pox – itchy blisters on skin.

Viral Diseases 5.Polio – affects nerves; victims can be paralyzed. “Iron Lung” – Helps a person breathe.

Viral Diseases 6.Small Pox – infects blood vessels; causes severe rash and fever. Has been declared “eradicated” – wiped out. 7.Yellow Fever – fever that causes liver damage and jaundice, a yellow-ish skin color due to the liver damage.

Viral Diseases 8.Viral Meningitis – inflammation (swelling) of nervous system; rash; headaches.

Viral Diseases 9.West Nile – flu-like symptoms; mosquito carried illness. 10.Ebola – fever, rash, circulatory system infection, and organ failure.

Treatment A method to treat a patient once they are already sick. Viruses – only symptoms can be treated; immune system “fights” virus on its own.

Antibiotics Treatment for bacterial infections. Antibiotics – kill bacteria cells.

Dose The amount of medicine a person takes based on age and weight.

Prevention Boosting a person’s immune system BEFORE contracting an illness, so the immune system can fight it off. Can be: vaccine, washing hands, sleep, exercise, etc.

Vaccine “Dead” or weakened form of a virus; injected to allow person’s immune system to fight it off on its own when it comes in contact with the virus.

Contamination When bacteria are present on unclean surfaces or food. Surfaces must be sanitized; food thoroughly cooked. Can lead to food poisoning / E.coli, salmonella.

Resistance Antibiotic resistance – when bacteria are not killed by antibiotics after several generations. Caused by overusing the same antibiotics.
