Transmission of Disease How do we get sick?

In order to catch an infectious disease, all four conditions listed below must occur  There is the presence of a germ or a pathogen  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

Susceptible host Portal of entry Mode of transmission portal of exit reservoir Causative agent

Mode of Transmission  Direct person to person animal to animal or person Mother to unborn child  Indirect almost anything desktops, purses, faucet handles, doorknobs

 If we can break the chain of infection and eliminate one of these four conditions, the infection cannot occur.  Good Handwashing  Proper PPE can eliminate the portal of entry and can prevent disease transmission.
