About Us

The Sylvie Ratelle STD/HIV Prevention Training Center (PTC) is a project of the Division of STD Prevention, Massachusetts Department of Public Health. We are part of the National Network of STD Clinical Prevention Training Centers, which are funded by the Centers for Disease Control and Prevention (CDC). In conjunction with regional medical schools and health departments, the PTC offers courses for health care providers in the diagnosis, treatment, and management of sexually transmitted diseases and the prevention of Human Immunodeficiency Virus (HIV).

These offerings meet a need for effective training in STD clinical services in support of disease prevention and are the primary source of post-graduate STD continuing education for health care professionals in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.

Clinical and on-line course offerings are designed for both new and experienced health care professionals (physicians, infectious disease fellows, nurse practitioners, physician assistants, certified nurse midwives, and nurses) in public and private practice who examine and treat individuals at risk for STDs/HIV. 

The Ratelle PTC offers courses taught by skilled and experienced faculty from regional Schools of Medicine, Nursing and State Health Departments, including the following:

As the longtime Medical Director of the MDPH Division of STD Prevention and HIV/AIDS Surveillance, Dr. Ratelle established the training center in 1995 to provide New England clinicians with state-of-the-art training in STD diagnosis, management and prevention. Over the years she worked tirelessly to establish the PTC of New England as a regional and national leader in the field of clinician training. She spearheaded the PTC’s expansion to include clinical training sites in Boston, Hartford, and Providence, and worked collaboratively with numerous organizations to develop innovative teaching tools, workshops and training curricula for the busy clinician.

One of her enduring legacies is the Sylvie Ratelle STD/HIV Prevention Training Center, providing opportunities for countless clinicians to benefit from local and national experts in the field of STD/HIV prevention training.
