Dear Neighbors,
Following up on last month’s community Alpha-gal survey, we are writing to share the aggregated results. Our goal is to keep the community informed and to support continued conversations around tick-related health concerns on the island.
A total of 23 individuals participated in the survey. Of these:
- 20 respondents reported that they have tested positive for Alpha-gal.
- 57% received their positive diagnosis in 2025, while 13% were diagnosed in 2024 or prior to 2020.
- 61% were tested in Rhode Island, with an additional 9% tested in both Connecticut and New York, and 4% in both New Jersey and Virginia.
- 96% of respondents indicated they are on Block Island more than five times per year.
- 91% of participants identified as year-round or seasonal residents.
Recently, BIHS and the Town met with the Rhode Island Department of Health and Dr. Samuel Telford to discuss our growing community concern. At this time, the Department of Health is working toward making Alpha-gal a statewide reportable condition.
In the meantime, Dr. Telford reiterated the importance of tick‑bite prevention. He emphasized that individuals spending time outdoors should wear permethrin-treated socks and ensure that pets are consistently treated with veterinarian-recommended tick preventatives.
From April through September, Dr. Telford has asked for the community’s help in supporting his research on tick species present on Block Island. Community members who experience tick bites are encouraged to:
- Tape the tick to an index card,
- Write the date of the bite on the card, and
- Drop it off at the Block Island Health Services.
BIHS will store collected samples until Dr. Telford retrieves them for analysis. Your participation provides valuable data that can help guide prevention and research efforts.
Thank you to everyone who participated in the survey and to all who continue to contribute to this important public health conversation.
