Diseases
Disease- Any harmful change in the health of
your body or mind.
 Microorganism- A living thing so small you
cannot see it with the naked eye.
 Pathogen- A virus or another agent that
causes a disease.
 Communicable Disease- Disease that can be
passed from person to person.
 Chronic- Long lasting disease.
 Acute- Short term disease.

Infectious Diseases


Caused by pathogens that
invade your body.
Examples: Common cold,
Influenza, Chickenpox,
Hepatitis, Strep Throat,
Tuberculosis
Non Infectious Diseases


Any disease not caused by
a pathogen.
Examples: Sickle Cell
disease, Cystic Fibrosis,
Muscular dystrophy,
Diabetes, Allergies,
Cerebral Palsy, Cancer
Types of Diseases
Causes
Virus- Tiny disease
causing particle that
invades healthy cells
to make more
viruses.
 Not living.
 AIDS, SARS, West
Nile, FLU/COLD

Bacteria- Tiny single
celled organism that
have no nucleus.
 Spread through
direct and indirect
contact.
 Living, Found
everywhere
 Most can be cured
with antibiotics.

Causes
Protist/ParasiteSmall single celled
organisms.
 More complex than
bacteria.
 Water supply,
Mosquitos
 Malaria, Giardia

Fungi- Complex
organisms that
cannot make their
own food.
 Over 100,000
species
 Athletes foot, Jock
itch,Yeast infections

STD’S, STI’S
STD- Sexually Transmitted Disease
 STI- Sexually Transmitted Infection
 Can be spread from person to person
through sexual contact.
 Sexual contact can be in the form of
vaginal sex, anal sex, oral sex or mutual
masturbation.

Chlamydia- Bacteria, burning during urination, discharge, may
show no symptoms.
Genital Herpes- Virus, fever, painful. Itchy genital sores,
burning during urination.
Genital Warts- Virus, Warts in genital area, may cause cervical
cancer
Gonorrhea- Bacteria, Unusual discharge from penis or vagina,
pain or burning during urination, may show no symptoms.
Trichomoniasis- Protozoa, yellowish, foul smelling discharge,
itching, may show no symptoms.
Syphilis- Bacteria, moist, red sores, rash, flu like symptoms,
brain damage
HPV- Virus, may show no symptoms, warts on the genital
area, possible abnormal Pap smear test, may cause cervical
cancer.
HIV and AIDS
Usually spread from sexual contact,
contaminated blood product, mother to
baby or shared needles.
 HIV stands for human immunodeficiency
virus. If left untreated, HIV can lead to the
disease AIDS (acquired immunodeficiency
syndrome).

What it Does…

HIV attacks the body’s immune system,
specifically the CD4 cells (T cells), which
help the immune system fight off
infections. If left untreated, HIV reduces
the number of CD4 cells (T cells) in the
body, making the person more likely to
get infections or infection-related cancers.
Over time, HIV can destroy so many of
these cells that the body can’t fight off
infections and disease.
