What will you learn? • Causes of infectious diseases • Who, What, Where? • Common infectious diseases • Bacterial • Viral • Preventing infectious diseases • Active immunity • Passive immunity
Infectious Diseases • “Disease caused by organisms that enter the human body and multiply.” • The history • Since the beginning of time.
What is the cause? • Most infections are caused by pathogens. • Pathogens live on all surfaces • Can spread through many different vectors and vehicles.
5 Causes 1. Bacterial 2. Viral 3. Fungi 4. Protozoan 5. Rickettsias
Bacterial Most are harmless Causes most respiratory illnesses Can be cured by antibiotics Viral Causes the most illnesses Causes most forms of the common cold Cannot be cured by antibiotics The Virus vs. The Bacteria
Spreading it around • Direct Contact • Indirect Contact • Animals • Vectors • Vehicles • Inanimate Objects • Environment
Getting Sick is Never Fun • Common Cold • Influenza • Tuberculosis • Strep Throat • Encephalitis • Meningitis • Mononucleosis
Common Cold • What is it? • Infection of your upper respiratory tract (nose & throat) • How did I get it? • Droplets in the air • Hand-to-Hand contact • Handling Contaminated Objects
Common Cold • What are the symptoms? • Appear 1 to 3 days after exposure to cold virus. • Runny or Stuffy Nose • Sneezing • Sore Throat • Cough • Congestion • Low Grade Fever (Up to 102 F)
Common Cold • How do I treat it? • No cure • Antibiotics do not treat cold viruses • Pain Relievers • Decongestant Nasal Sprays • Cough Syrups
What is it? Viral infection of the respiratory tract (nose, throat, bronchial tubes, lungs) How did I get it? Spread through droplets in the air What are the symptoms? High grade fever (101 F) Chills and Sweats Dry Cough Headache Body aches & weakness Congestion Influenza (The Flu)
Influenza (The Flu) • How do I treat it? • Bed Rest • Plenty of fluids • Antiviral Medications may be prescribed by doctor • Get your flu shot!!!
Tuberculosis • What is it? • Bacterial infection that affects your lungs • TB infection vs. active TB • Very dangerous! (active TB) • How did I get it? • Highly contagious (active TB) • Spread through droplets in the air
What are the symptoms TB infection: No symptoms Not contagious Active TB: Cough lasting 3 or more weeks Pain with breathing & coughing Slight Fever Unexplained weight loss Chills Night Sweats Tuberculosis
Tuberculosis • How do I treat it? • TB infection: • TB medication INH used for 6-9 months • Active TB: • Several TB medications • Hospitalization
What is it? Bacterial throat infection How did I get it? Streptococcal bacteria Highly contagious Bacteria spread through droplets in air What are the symptoms? Sore throat Red, swollen tonsils Swollen, tender lymph glands (in neck) Fever Headache Strep Throat
Strep Throat • How do I treat it? • Antibiotics • Treating strep is very important!
Encephalitis • What is it? • Viral infection causing inflammation of the brain • Can be life-threatening • How did I get it? • Insects • Other viruses
What are the symptoms? Drowsiness Seizures Sudden Fever Severe Headache Nausea and Vomiting Stiff neck How do I treat it? Mild infections: Rest, healthy diet, plenty of fluids More severe infections: anti-viral drugs Encephalitis
Meningitis • What is it? • Inflammation of the meninges • Can be viral or bacterial • Meningococcal Meningitis • How did I get it? • Spread through air droplets and direct contact with an infected person
Meningitis • What are the symptoms? • High fever • Severe headache • Vomiting and nausea • Seizures • Confusion • Sleepiness
Meningitis • How do I treat it? • Meningococcal Vaccine available! • Bacterial meningitis: • Immediate treatment VERY IMPORTANT • Requires IV antibiotics
Mononucleosis • What is it? • Mono- “The Kissing Disease” • Virus • How did I get it? • Virus is transmitted through saliva
What are the symptoms? Weakness Sore throat Fever Swollen lymph nodes & tonsils Skin rash How do I treat it? Bed Rest Plenty of fluids Mononucleosis
Lets Experiment with Each Other • WARNING: Do Not sniff, drink, or spill the liquid in your cups! • Follow instructions carefully. • Have fun!
Active Immunity Life long immunity Developed over time Ex: Disease A: Chicken Pox Bacteria A Bacteria Aa Passive Immunity Temporary immunity Few months Mother to baby How?
Vaccines • 3 major types • Live Virus • Made from weakened virus strain • Killed Virus • Cause body to produce antibodies • Toxoids • Destroys toxic properties
Always wash your hands Keep your house clean If some is sick do not: Kiss Hug Be in close contact Never share your toothbrush The “five second rule” does not exist. Cook food completely Maintain healthy diet It’s Common Sense!
