Infectious Diseases
Four main types of infectious agents
bacteria
protozoa
- release tissue damaging toxins
- could be transmitted by physical contact or through the air
- spread through the body by attaching to cells to multiply.
- make you sick when they become human parasites
- through contaminated food, water, the bite of an insect, or person-to-person contact
- parasites spread through the body when they enter the blood stream
fungi
Disease prevention
- make you sick by feeding off living material which could cause an infection
- produce microscopic spores which can cause fungal infections
- contact and inhalation of the spores causes disease
- spores can be in the air or the soil.
Stay Clean
viruses
- viruses inject their genetic material into the cell causing the cell to make copies of the virus
- Viruses are spread through the air and physical contact
Get Vaccinated
- Wash your your hands- the obvious thing to do, wash your hands before you eat or prepare food.
- Take showers or baths at regular
- Keep your house clean- leaving food around and letting it go bad could cause fungi, bacteria, mold, or anything else to grow.
- injection of a dead or weakened disease- causing microorganism
- can't cause disease but it builds up the immune system against the disease
- this type of immunity can last very long
