The Spreading of Disease


The spreading of disease infection

The Spreading of Disease: Infection

  • Infectious diseases spread in one of four ways:

    • Contact with infected person

    • Contact with contaminated object

    • Contact with infected animal

    • Contact with environmental source


Carrier vs vector

Carrier vs. Vector

  • Vector—insect spreading disease (tick, mosquito)

  • Carrier—organism that has a virus or bacteria but not showing the signs of the disease.

    • Person with HIV


Antibiotics

Antibiotics

  • Antibiotics work on bacterial infections

    • Bacteria can become antibiotic resistant

      • Due to overuse or not taken the medicine as prescribed.

  • Examples of antibiotics:

    • Z-packs, CepCor, Penicillin, etc


Penicillin

Penicillin

  • Alexander Fleming discovered penicillin by accident

    • Penicillin is a fungus


Vaccines

Vaccines

  • Vaccine—a weakened or dead version of the actual virus/bacteria given to you to force your immune system to build antibodies against the disease.

    • Flu shot


Your body

Your Body

  • Pathogen—a microbe that cause disease

  • Antibodies—kill pathogens in body

  • Activity Immunity—organism gets virus and builds up antibodies for virus

  • Passive Immunity—inject with antibodies from another organism
