• There is a large enough quantity of the germ or
  pathogen
• There is a portal of entry into the body
• The immune system is weak

Mode of Transmission

• Direct
• person to person
• animal to animal or person
• Mother to unborn child
• Indirect

• If we can break the chain of infection and
  eliminate one of these four conditions, the
  infection cannot occur.
• Good Handwashing

  can prevent disease transmission.
