Abstract

BACKGROUND

Lepidopterism refers to moth- or butterfly-associated illness, including contact dermatitis, urticaria, and occasional systemic reactions. Lepidopterism outbreaks are rare.

OBJECTIVE

To investigate a lepidopterism outbreak associated with caterpillars of the Douglas-fir tussock moth (DFTM; Orgyia pseudotsugata) among Boy Scouts attending summer camp in New Mexico.

METHODS

Retrospective cohort analysis; environmental investigation.

RESULTS

Attendees were primarily male (100/107; 94%) and less than 18 years old (82/107; 77%). Itch, rash, or hives were reported by 56 of 102 (55%) of campers. Patients were more likely to report direct caterpillar contact (relative risk [RR]: 2.7; 95% confidence interval [CI], 1.3-5.5); playing a caterpillar-flicking game (RR: 1.9; 95% CI, 1.1-3.4); and sleeping at campsite 6, where caterpillars were most numerous (RR: 1.7; 95% CI, 1.3-2.4). All patients recovered.

LIMITATIONS

Data on disease status and risk factors were collected retrospectively.

CONCLUSION

Modifying behaviors associated with lepidopterism and avoiding areas of heavy infestation can reduce illness risk.

摘要

背景

鳞翅目昆虫症是指与蛾类或蝴蝶相关的疾病，包括接触性皮炎、荨麻疹以及偶尔出现的全身反应。鳞翅目昆虫症的爆发较为罕见。

目的

调查新墨西哥州参加夏令营的童子军中与花旗松毒蛾（DFTM；Orgyia pseudotsugata）毛虫相关的鳞翅目昆虫症爆发情况。

方法

回顾性队列分析；环境调查。

结果

参与者主要为男性（100/107；94%）且年龄小于18岁（82/107；77%）。102名露营者中有56名（55%）报告出现瘙痒、皮疹或荨麻疹。患者更有可能报告直接接触毛虫（相对风险[RR]：2.7；95%置信区间[CI]，1.3 - 5.5）；玩弹毛虫游戏（RR：1.9；95% CI，1.1 - 3.4）；以及在毛虫数量最多的6号营地睡觉（RR：1.7；95% CI，1.3 - 2.4）。所有患者均康复。
