Early Release - New World Ocular Dirofilariasis Caused by Dirofilaria repens Infection, United States - Volume 32, Number 7—July 2026 - Emerging Infectious Diseases journal - CDC

Abstract

We describe an infection caused by Dirofilaria repens nematodes in California, USA. A firm nodule developed after an insect bite on a patient's eyelid. Excision with morphologic and molecular analysis confirmed D. repens infection. Our findings confirm the necessity of both molecular and histological studies to identify nematode infections.
