Activity Description

Chiggers are the larvae of the Trombiculidae mite species. Bites from these mite larvae can cause local pruritus and irritation called trombiculiasis or trombiculosis. The reaction is usually mild and self-limited, but the bites can transmit disease or result in bacterial superinfection. While there are many species of parasitic mites in a variety of habitats worldwide, the species most commonly referred to as chiggers include Eutrombicula alfreddugesi in the south of the United States, Trombicula autumnalis in Europe, and the Leptotrombidium genus in Asia-Pacific. 

The larvae of these species feed on the skin of various animals, including humans. An inflammatory reaction with surrounding erythema, a variable degree of swelling, and intense pruritus occurs. The larvae easily dislodge by scratching and rarely remain attached to humans for more than 48 hours, but the intense pruritus, inflammation, and localized allergic response may last for weeks. Typically, the diagnosis of trombiculiasis is based on a history of exposure to a trombiculid habitat, the characteristic lesion pattern, and the exclusion of other possible diagnoses. The management of chigger bites is focused on symptom control with oral antihistamines or topical corticosteroid creams. This activity for healthcare professionals aims to enhance learners' competence in diagnosing chigger bites, symptomatic management, implementing preventive strategies, and fostering effective interprofessional teamwork to improve outcomes.
