| Sterile | 0 pathogens/microorganisms |
| Vector | An animal, especially an insect, that transmits pathogens from infected to non infected persons Can carry pathogens on their body or inside their body, they are indirect |
| Terminal sterilization | Process of sterilizing articles after they have been used and before putting them into circulation |

| Occurrence of infection | *Portal of entry *Resistance of host *Number of organisms *Virulence of the organism |
| Types of infections | *Primary *Secondary *Mixed *Latent |
| Secondary | Usually caused by opportunistic type |
| Mixed | Appendicitis, trench mouth, wound infection |
| Latent | Early TB, malaria |
| Acute | Runs a rapid and severe course terminating abruptly |
| Chronic | Runs a slow course over a long period of time; may last for weeks to years |
| Acute | Period of actual illness with symptoms, degree of fever, and length of time depending upon the disease, condition of patient and treatment |

| Incubation | Period between entrance of organisms to the body and onset of symptoms |
