Essential Question:
Why is it important to remain germ free?
Enduring Understanding: Students will understand that
pathogens are spread through direct contact, indirect
contact, through impure food or unclean water, and
contact with animals or insects.
DO NOW
What can you do to remain germ free at school and away?
protozoa
 Noncommunicable
diseases
fungi
Single-celled organisms that have a
nucleus
Diseases that do not spread
Primitive single- or many-celled organisms that
cannot make their own food
In this lesson, you will learn to
 identify the two main types of disease.
 recognize four common disease-causing organisms.
 describe how germs spread.
Analyzing a Graphic
Create a concept map
that shows how germs can
be spread.

What Is a Disease?
The science of fighting disease has come along way
in the past hundred years.
disease A condition that affects the proper
functioning of the body or mind
Types of Diseases
The two basic categories of diseases are:
Communicable diseases
Noncommunicable disease
communicable diseases Diseases that can be spread.
Example : Cold, Flu, Fever.
noncommunicable diseases Diseases that do not spread.
Example: Diabetes, Cancer, Heart Disease.
Germs that Cause Disease
Pathogen is the scientific name for germ.
pathogen A microscopic organism that causes
communicable diseases
Four Classes of Pathogens
Viruses
Bacteria
Protozoa
Fungi
Germs that Cause Disease
Some viruses are harmless and some cause
diseases.
viruses Tiny, nonliving particles that invade and
take over healthy cells
The common cold, the flu, the measles, and AIDS
are examples of diseases caused by viruses.
Germs that Cause Disease
Bacteria is everywhere.
bacteria Extremely small single-celled
organisms with no cell nucleus
Strep throat, Lyme disease, and tooth decay are
examples of disease caused by bacteria.
Germs that Cause Disease
Protozoa can be harmless, but some strains can
cause serious disease.
protozoa Single-celled organisms that
have a nucleus
Malaria is an example of a disease caused by
protozoa.
Germs that Cause Disease
Fungi survive by breaking down other living
organisms and absorbing their nutrients.
fungi Primitive single- or many-celled organisms
that cannot make their own food
Some strains of fungi, such as molds, athlete’s foot
and ringworm.
How Germs Are Spread

Insects

Enduring Understanding:
Communicable diseases can be prevented with good hygiene
practices and vaccines.
In this lesson, you will learn to
 recognize ways pathogens are spread.
 identify common communicable diseases.
 demonstrate healthful behaviors that limit the spread of pathogens.
Common Communicable Diseases
When symptoms of a cold first appear, you are
contagious.
contagious Spreading a virus to others
by direct or indirect contact
The cold is the most common communicable
disease.
Common Communicable Diseases
Symptoms of influenza, or “the flu,” include
high fever and joint and muscle aches.
Hepatitis
Hepatitis
Inflammation of the liver, caused by a virus or a toxin and
characterized by jaundice, liver enlargement, and fever.
Disease
Symptoms
Treatment
Hepatitis A, B, and C
Weakness, fatigue, nausea,
vomiting, fever, yellowing of eyes,
abdominal pain, dark urine
Rest, healthful food choices
(medication for Types B and C)
Strep Throat
Strep throat
It is a bacterial throat infection that can make your throat
feel sore and scratchy.
Disease
Symptoms
Treatment
Strep throat
Sore throat, fever, chills, body
aches, loss of appetite, nausea,
vomiting, swollen tonsils or glands
Antibiotics, soft foods, liquids,
gargling with salt water
Keep it to Yourself
When you have a cold, take action to prevent spreading
your cold to others. Be careful to cover your mouth and
nose when you cough or sneeze. Avoid sharing cups,
utensils, or other personal items.
Your Body’s Defenses
In a typical day, your body is exposed to millions
of germs.
You aren’t sick all the time because your body is
protected by its own defense system.

Your Immune System
Your immune system is your second line of
defense.

and organs that fight disease
Your Immune System
Some lymphocytes attack pathogens directly while
others produce antibodies.
lymphocyte A white blood cell that attacks
pathogens or harmful germs
antibodies Chemicals produced specifically to
fight a particular invading substance
Your Immune System
Antibodies recognize germs that reenter the body
and will attack and destroy them.
This is called immunity.
immunity Resistance to infection
Preventing Communicable Diseases
Steer clear of
people who you
know are sick.
Get in the habit
of washing your
hands regularly.
Get enough rest,
eat healthy foods,
and exercise.

are avoidable

diseases (STDs) person to another through sexual activity
 HIV
A virus that causes AIDS
 AIDS
A condition characterized by life-ending
infections and a T-cell count under 200

In this lesson, you will learn to
 identify common STDs.
 describe how HIV and other STDs are spread.
 access current information on HIV and AIDS.
 explain how to protect yourself from STDs.
HIV
Organizing Information
There are many myths and
facts about the spread of HIV.
As you read, keep a list of
both in your notebook.
Myths
Facts
Sexually Transmitted Diseases
Anyone who is sexually active can get sexually
transmitted diseases (STDs).
sexually transmitted Communicable diseases spread from one
diseases (STDs)
person to another through sexual activity
Another name for STDs is STIs (sexually transmitted
infections).
Sexually Transmitted Diseases
STDs can cause:
Damage to menstrual health
Damage to the reproductive
system
An inability to have children
Death
Sexually Transmitted Diseases
STD
Common Symptoms
Chlamydia
Pain or burning feeling during urination; unusual discharge from penis or
vagina; often has no symptoms but can still be spread
Gonorrhea
Pain or burning during urination; unusual discharge from penis or vagina;
abdominal pain; sometimes has no symptoms but can still be spread
Syphilis
Red, wet, painless sores at place where virus enters body, followed by rash and
flu-like symptoms; can lead to brain damage and other serious health problems,
especially in infants
Genital warts
Small pink or red bumps in genital area; can increase risk of certain cancers
in women
Genital herpes
Itching or pain followed by painful, itchy sores in genital area; symptoms come
and go, but virus is still present and able to spread
Hepatitis B
Weakness, fatigue, nausea, vomiting, fever, yellowing of eyes, abdominal pain,
dark urine
HIV and AIDS
HIV stands for human immunodeficiency virus.
HIV The virus that causes AIDS
The HIV virus replaces a T-cell’s genetic information
with its own and then multiplies. This compromises
the body’s ability to fight pathogens.
HIV and AIDS
When the T-cell count drops so low that the immune
system can no longer protect the body, AIDS, or
acquired immunodeficiency syndrome develops.
AIDS A condition characterized by life-ending
infections and a T-cell count under 200
Drugs can delay the onset of AIDS, but there is
no cure.
How HIV Spreads
HIV is spread through the following bodily fluids:
Semen
Fluid from the vagina
Blood
Breast milk
How HIV Spreads
HIV is spread from person-to-person:
Through sexual contact
Sharing needles
When an infected mother passes it on to her
developing baby

HIV enters the
bloodstream.

As the virus multiplies,
more and more
lymphocytes are
destroyed. The immune
system gets weaker
and weaker.
HIV
T-cell
4
Dead T-cell
The virus attacks
and damages T-cell
lymphocytes. These
cells are an important
part of the immune
system.
Death occurs when
the immune system
is too weak to fight off
infections that a
healthy immune
system could easily
resist.

How HIV Spreads
You cannot get HIV from:
The air
Mosquito bites
Sweat or tears
Touching objects
Shaking hands or hugging
Treatment for People with HIV and AIDS
Medical technology has slowed down the effects of
HIV and allow infected people to live longer.
There is no cure for HIV or AIDS.
Detecting HIV
People with HIV often show no symptoms for a long
time, but the virus can still be passed on to others.
