Disease?
An abnormal condition that affects the body.
Disease
Symptoms:
& Noncommunicable Diseases
environmental effects
pathogens
(Germs):
any microbes that cause a disease
autoimmune disease
An abnormal response to something normally present in the body.
genetic disorders
A disease due to a defect in a gene or due to a chromosomal abnormality.
name that pathogen
what about cancer?
In cancer, cells divide repeatedly to form a tumor.

(Non-stop mitosis!)

If a tumor is malignant (or cancerous), it will invade other body parts.

It can also spread throughout the body via the circulatory or lymphatic system.
immune system
The body system responsible for fighting diseases.
White blood cells identify and destroy pathogens.
cures
White blood cells can only do so much.
If they can not kill the disease on their own, then you need medicine.
Antibiotics - fight bacteria
Vaccines - prevent viruses
epidemic
what if medicine does not exist?
If medicine is not available or does not work, a disease can spread uncontrollably.

That is called an epidemic.
2 Types:
Communicable (Infectious) Diseases
pathogens
autoimmune disease
genetic disease
bacteria
Common Diseases:

protozoa

Characteristics:
usually unicellular
more complex than bacteria
harmless or harmful
usually found in water
viruses
Common Diseases:
Colds, Flu, Chicken Pox,
Measles, Mono, Mumps, Hepatitis, HPV, polio, rabies, yellow fever,
Ebola,

Herpes, HIV!
fungus
Common Diseases:
athlete's foot
yeast infections
ringworm
Characteristics:

uni- or multicellular
includes molds, yeast, & mushrooms
helpful & harmful
parasites
prevention:
How can you prevent the spread of disease to you/others?

Oh Herpes.

May or may not be considered “alive”
Transmit DNA/RNA sequence to be converted and read in hosts

Viruses

Organisms that must live on/in a host for survival
Host: the organism in which a parasite lives all or part of its live
Humans can be “hosts” of tapeworms

Parasites

YEAST can cause infections


OTHER DISEASES:
- athletes foot
- ringworm

FUNGUS among us

Eukaryotes
Multicellular (with the exception of yeast)
Sexual Reproduction via spores
AIR
Moist, dark places

Fungus

PROTISTS

Eukaryotic organisms (with nucleus)
Usually in aquatic environments
Capable of locomotion
Usually found in water

Protists

Streptococcus (Strep Throat)
Tuberculoses, TB
Staphylococcus Infection
Salmonella
Gonorrhea
Syphilis
E. Coli
Lyme Disease

BACTERIA

Entamoeba histolytica - dysentery

Giardia lamblia, sucking disk

Trichomonas vaginalis

Examples

PROTISTS

MOLD spores cause allergies

FUNGUS among us…

chlamydia
gonorrhea
Salmonella
E. Coli
Staph /MRSA
Lyme Disease
tetanus
pneumonia
tuberculosis (Tb)
strep throat
whooping cough
how do you transmit bacteria pathogens?
MRSA (Staph Infection:)

Salmonella:

Common Disease:
amoebic dysentery
malaria
STD: trichomoniasis

brain eating, dysentery
Malaria:
Trichomoniasis (STD):
Ebola vs HIV
Picture: A picture of each virus. Draw it. Do not print it out.
Transmission: How is the disease transmitted between people?
Symptoms: What are the symptoms?
Time: How long is it before a victim shows symptoms?
Worldwide Death Toll: How many people in world died from virus?
U.S. Death Toll: How many people in U.S. died from virus? (Per Year? So far?)
Prevention: How can a population prevent this viral infection?
Treatment: How is your virus treated?
Vaccine: Is there a vaccine available? What is the status of this vaccination?
In your team, design a poster that convinces the WHO to allocate funding to your disease (virus).
Jobs: researcher, artist, designer, recorder, etc.
Facts to include:
Characteristics:

Parasites are organisms that
depend
upon another for survival.

The parasite hurts the organism it lives in/on (called a host).
Examples (Common Diseases):

tapeworms, ticks, lice, bed bugs, leeches, hookworms, pinworms
Good Hygiene
See a doctor if you have strange symptoms
Cook meat!
Wash your hands!
allergies
cancer
disease:
an abnormal condition that affects the body
fever
itchy eyes
shivers
infection
when pathogens enter the body, multiply and cause harm
communicable (infectious) disease
Diseases spread to the body from a pathogen.

Contagious:
When pathogens spread person to person
airborne:

DISEASE TRANSMISSION:
How do you get a pathogen?
rash
sweating
cough
Any change in the normal balance, or homeostasis, in the body.
new year's resolutions
be happy
work hard
be healthy
sore throat
runny nose
irregular bowel movements
Microbes:

organisms so small they can only be seen with a microscope
Characteristics:

only made of DNA and protein
MUST infect a host in order to move and reproduce
Treatment/Prevention:
Can only be prevented with vaccinations.

caused by nonstop mitosis of abnormal cells
an immune response by the body to a foreign substance
the body's immune system attacks healthy cells
inherited disease caused by DNA mutation
disease contributing to environmental factors
* Some diseases are a mix of these!
