Medical English: Key Phrases for Public Health and Statistics
Public health is all about keeping whole communities safe and healthy. To do this, experts use math and data to spot health trends. If you work in medicine, you need to know how to talk about these numbers in English. Words for Tracking Diseases
When a sickness spreads, health workers must track how fast and far it goes. These words help you describe how a disease behaves in a population.
Outbreak: A sudden rise in cases of a disease in one specific place.
Epidemic: A large spike in a disease that spreads quickly across a country or region.
Pandemic: An epidemic that spreads over many countries or the whole world.
Endemic: A disease that is always present in a certain area, like malaria in some tropical places. Useful Phrases to Use: “We need to contain the local outbreak before it spreads.”
“Flu numbers show that the illness is endemic to this region.” Phrases for Measuring Sickness and Death
Public health data relies heavily on rates. Rates help us understand the risk of getting sick or dying.
Morbidity rate: The percentage of people who get a specific sickness in a group.
Mortality rate: The percentage of people who die from a disease in a set amount of time.
Incidence: The number of new cases of a disease during a specific time.
Prevalence: The total number of cases (both old and new) existing in a population at a specific time. Useful Phrases to Use: “The incidence of diabetes rose by five percent this year.”
“Smoking directly increases the mortality rate for lung diseases.” Talking About Risk and Prevention
A big part of public health is stopping problems before they start. You will often need to talk about risk factors and how well a treatment works.
Risk factor: Something that increases your chance of getting a disease, like a bad diet or smoking.
Prevention: Action taken to stop injury or illness from happening.
Efficacy: How well a vaccine or medicine works under ideal laboratory conditions.

When you share health statistics, you must explain where your data comes from and what the numbers mean.
Sample size: The number of people who took part in a medical study.
Statistically significant: A mathematical phrase meaning the results of a study were likely not a fluke or an accident.
Correlation: A link or connection between two things, though one might not cause the other. Useful Phrases to Use:
