Allegheny County Health Department - STI/HIV

Welcome to the Allegheny County Health Department (ACHD) website. Our mission is to protect, promote, and preserve the health and well-being of all Allegheny County residents, particularly the most vulnerable. We strive daily to assure quality public health services to more than 1.2 million county residents. In September of 2017, we became a nationally accredited public health department.

Great progress has been made to improve the health of our community; however, there is still much to be done to make Allegheny County the healthiest county in the nation. We continue to face many challenges, including air quality, smoking, obesity, lead exposure, chronic disease and overdoses. Our Plan for a Healthier Allegheny (PHA) highlights important issues and brings together stakeholders across multiple sectors to address our top priorities. The PHA sets the stage for health improvement.

Your public health department strives to support healthy behaviors, improve environmental health and build a culture of health in all 130 municipalities in our county.
