Dr. Ellen Levy Koenig: HIV/AIDS Research Pioneer in Dominican Republic Passes Away
Dr. Ellen Levy Koenig, a pioneer in HIV/AIDS research in the Dominican Republic, died on June 22 in Santo Domingo. According to a statement from the country’s medical and scientific community, she is recognized for documenting the first HIV seroprevalence in the region and treating over 2,500 underserved patients through the Instituto Dominicano de Estudios Virológicos.
How did Dr. Ellen Levy Koenig impact HIV research in the Caribbean?
Dr. Levy Koenig established the Dominican Republic’s presence in international medical research during the 1980s. In 1987, she co-authored a study with her brother, Dr. Jay A. Levy, titled “Prevalence of antibodies to the human immunodeficiency virus in Dominicans and Haitians in the Dominican Republic.”

Published in the journal JAMA, this research analyzed samples collected since 1983. The medical community states this work first documented HIV seroprevalence in the country’s populations and helped researchers understand virus transmission dynamics on the island of Hispaniola.
Her research also covered other viral infections. In 1992, she published a study in AIDS Research and Human Retroviruses regarding HTLV and its link to neurological diseases in Dominican patients.
What were her clinical contributions to patient care?
Levy Koenig began her leadership roles in 1985 as the Director of Virology at the Laboratorio Nacional Dr. Defilló. In this role, she worked to identify and treat seropositive patients.
After earning her medical degree in 1991, she opened a medical practice dedicated exclusively to people living with HIV and AIDS. This occurred during a period when the medical community noted there was significant stigma surrounding the disease.
In 2000, she founded the Instituto Dominicano de Estudios Virológicos (IDEV). As the director and lead researcher, she oversaw the delivery of medical, psychological, and social assistance to more than 2,500 low-income patients.
What happens next for her legacy and the medical community?
The Dominican medical community stated in a communiqué that Levy Koenig’s name “will remain forever in the history of the country’s medicine.”

The continued operation of the Instituto Dominicano de Estudios Virológicos (IDEV) may serve as the primary vehicle for her ongoing influence on regional healthcare. Future epidemiological approaches in the region could continue to rely on the foundational transmission dynamics she documented in the 1980s.
Funeral services are scheduled for June 23 at Funeraria Blandino from 12:00 p.m. to 6:00 p.m. The burial will take place June 24 at 10:00 a.m. at the Jewish Cemetery in Santo Domingo.
