Study Notes
Infection Control Measures and Disease Prevention
- 1 in 9 women in Long Island will develop breast cancer
- Mortality rate measures the percentage of the population that dies due to a disease within a specific period of time
- Epidemic refers to the widespread occurrence of an infectious disease in a community at the same time
- Pandemic is an epidemic over a large geographical area affecting a large portion of the population
