Warm-up

•Pre Test!

Page 2: Warm-up Pre Test!. Pre Test Something that can be spread from person to person or though the environment Though contaminated object, vectors, and contaminated.

Pre Test

• Something that can be spread from person to person or though the environment

• Though contaminated object, vectors, and contaminated food and water

• A virus is a piece of genetic material surrounded by a protein coat, while bacteria are single celled microorganisms that live almost everywhere on Earth

Pre Test

• The Symptoms of the flu, which include high fever & fatigue, are more serious that the symptoms of the common cold

• Avoid close contact with sick people, wash your hands often, & avoid touching your mouth, eyes, & nose

• Hepatitis cannot be treated with antibiotics because it is causes by a virus

Communicable Diseases

Learning Targets

• Identify pathogens that cause communicable diseases

• Explain the causes of:– Transmission– Symptoms– Treatment

Communicable Diseases

• A Communicable disease is a disease that is spread from one living thing to another of through the environment.

• Communicable disease are caused by Pathogens

• Remember: Non-Communicable disease are not transferable to others.

Pathogens

• A Pathogen is an organism that causes disease. Pathogens include:– Bacteria– Viruses– Fungi– Protozoans– Rickettsias

Pathogens

• Bacteria: Are single celled micro-organisms that live almost everywhere on earth.

• Most are harmless• Many are essential for life

– Digest food – Make some of the vitamins you need

• Multiply through cell division

• Examples– Tetanus– Salmonella– Lyme Disease

Pathogens • Viruses: are pieces of genetic material surrounded by a protein coat

• By themselves that are inactive

• Need living cells to reproduce• Run their course & eventually

are killed by the immune system

• Antibiotics do NOT work against viruses

• Invade all forms of life– Mammals, plants, bacteria

• Examples– Mononucleosis– Cold– Chickenpox– Ebola

Pathogens

• Fungi: Plant like• Diseases of the skin• Diseases of

membranes or lungs

• Examples– Athlete’s Foot– Ringworm– Jock Itch

Pathogens

• Protozoans: single celled organisms that are larger and more complex than bacteria

• Most are harmless• Those that cause disease are found in people

with weak immune systems

• Examples– Malaria– Dysentery

Pathogens

• Rickettsia: pathogens that resemble bacteria• Act like viruses • Come through the bites of insects

• Examples– Rocky Mountain Spotted Fever– Australian tick typhus
