STANDARDS

PHW 1.8.9 Summarize health practices to prevent the spread of infectious diseases that are transmitted by food, air, indirect contact, and person-to-person contact

ESSENTIAL QUESTIONS

What are communicable diseases? What are the differences between

pathogens? How can we prevent the spread of

diseases?

VOCABULARY

Disease Communicable diseases Germs Pathogens Viruses Bacteria Fungi Protozoa

PATHOGENS

Germs that cause diseases Infection is a condition that happens

when pathogens enter the body, multiply, and cause harm.

Communicable diseases are all caused by pathogens.

Viruses, Bacteria, Fungi, Protozoa

VIRUSES

The smallest and simplest pathogen Are not alive Made up of genetic material and

protein. What are some example of some

viruses?

EXAMPLES

Common cold Chicken pox Influenza (the Flu) Hepatitis Herpes HIV pneumonia

BACTERIA

The simplest ONE- celled organisms. Exist in every environment on earth Some are helpful Helpful bacteria live in your digestive

system to break down food Harmful bacteria causes diseases such

as strep throat and pneumonia

EXAMPLES

Pinkeye Whooping cough Tuberculosis Gonorrhea

FUNGI

Organisms that are more complex than bacteria but cannot make their own food.

Most are harmless but some can cause disease

Molds Yeast Mushrooms Most common; Athletes foot, ring worm

PROTOZOA

One celled organisms that are more complex than bacteria.

Most commonly transferred to people through mosquito bites, contaminated water/food

Also referred to as parasites Malaria

HOW PATHOGENS SPREAD

Direct contact with others spread directly from person to

person. example: person with pinkeye might

wipe their eye then shake someone hand. That person touches their eye and could get pinkeye.

INDIRECT CONTACT WITH OTHERS

Spreading through the air. Sharing drinking glasses, eating

utensils and other personal items. Example: someone with a cold or sore

throat could sneeze or cough and send pathogens in the air. Anyone breathing that air can become infected.

CONTACT WITH SOMEONE ELSE'S BLOOD Pathogens such as Human

Immunodeficiency Virus (HIV) can spread when blood from an infected person comes in contact with someone else’s blood.

Using unclean needles

CONTACT WITH CONTAMINATED FOOD/WATER

Undercooked meat may still contain bacteria.

Food-borne illnesses What are some healthy tips when

cooking? Some pathogens spread through

contaminated water. Never drink water directly from lakes

and rivers.

EVENT: AMIE COPELAND

May 9, 2012SNELLVILLE, Ga. -A 24-year-old West Georgia graduate student had to have her leg amputated after getting an infection following a zip line accident.

Aimee Copeland severely cut her left leg while zip-lining in a friend's backyard near Carrollton. She contracted a flesh-eating bacteria infection that forced doctors to amputate the leg.

CONTACT WITH ANIMALS AND INSECTS Animals that carry rabies virus can

infect other animals and humans. Mosquitoes infected with the west nile

virus can spread that to birds, horses and humans.
