About Us

The 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/HIV Prevention Training Centers, which are funded by the Centers for Disease Control and Prevention (CDC). In conjunction with regional medical schools, health departments, and the National Laboratory Training Network (NLTN), the PTC offers courses for health care providers and laboratorians 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 clincial 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. Laboratory courses are designed for health care professionals and laboratorians who perform or plan to perform laboratory testing for the diagnosis of STD.

About Sylvie Ratelle

Sylvie Ratelle, MD, MPH was the founding director of the STD/HIV Prevention Training Center of New England (PTC). 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. Dr. Ratelle was a staunch advocate for STD/HIV prevention, an astute mentor, a giving and caring colleague, and a great friend.

In 2006, Dr. Ratelle passed away after a long and courageous battle with breast cancer at the age of 51. 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.
