Environmental health IS public health. Asthma, lead exposure, heat illness, these are neighborhood-level policy failures, not individual bad luck. #PublicHealth#HealthEquity
Most people already know smoking is harmful. The challenge in public health was never awareness, it's behavior change. Information alone doesn't move populations. Environments do. #PublicHealth#HealthPromotion
Health is built in zip codes, not hospitals. Income, housing, food access, and neighborhood safety shape population health long before anyone sees a doctor. https://t.co/OddC7e1ODA #PublicHealth#HealthEquity
Biostatistics answers the question every public health pro faces: is this health improvement real, or just chance? It's not just math, it's how data becomes evidence. https://t.co/OddC7e1ODA #PublicHealth#Biostatistics
A screening test can cause harm even when it's "working." False positives = unnecessary treatment. False negatives = delayed care. Sensitivity and specificity exist for a reason. #Epidemiology#PublicHealth
Smoking is a risk factor for lung cancer, not a guarantee. Epidemiologists still have to rule out confounding and bias before calling it a cause. That distinction is all of public health. #Epidemiology#PublicHealth
Epidemiology's core insight: disease isn't random, it follows patterns. Find the pattern, prevent the harm. That's public health. https://t.co/OddC7e1ODA #Epidemiology#PublicHealth
In epidemiology, an outbreak can be 10 people at one restaurant, "more than expected" is the threshold that triggers investigation and drives public health action. #Epidemiology#PublicHealth
Prevalence = how many have it. Incidence = how many are getting it. One drives care planning. The other drives prevention. Master the difference. #Epidemiology#PublicHealth
Medicine treats one patient. Public health asks why the whole neighborhood is sick, pollution, housing, air quality. That's upstream thinking. #PublicHealth#MPH
