ACHD: Bureau of Assessment, Statistics, and Epidemiology (BASE)

Formed in 1957, ACHD strives daily to assure quality public health services by promoting individual and community wellness, preventing injury, illness and
premature death or disability, and protecting the population from harmful effects of chemical, biological, and physical hazards within the environment.
Today, we serve more than 1.2 million county residents in southwestern Pennsylvania.
Through the years, public health has made great strides when it comes to infant mortality, childhood immunization, cancer, heart disease, and
tuberculosis, to name a few. ACHD is one of ten county and municipal health departments in Pennsylvania, and operates as a semi-autonomous health
department from the PA Department of Health.
