RESUMO
Lyme disease is a multiorgan animal‑borne disease caused by the spirochete Borrelia burgdorferi. This case series highlights its presence in Haryana, a nonendemic zone. The first case was a 27‑year‑old housewife who presented with an annular erythematous patch with a central papule following an insect bite on the left upper arm. The second case was a 32‑year‑old farmer who gave a history of insect bite on the right arm followed by the development of an erythematous patch with a central blister. The third case, a 17‑year‑old boy presented with a history of tick bite over right thigh and a typical bull’s eye lesion with central ulceration. These cases were managed with oral doxycycline 100 mg twice daily for 14 days. The fourth case was a 7‑year‑old boy with typical erythema migrans on the right check and neck while the fifth case, a 30‑year‑old housewife, presented with an erythematous patch with a central papule on the right buttock. These patients were treated with oral amoxycillin 25 mg/kg, thrice daily for 14 days. All patients showed IgM antibodies to B. burgdorferi. Treatment led to clearance of lesions in all the patients. Lyme borreliosis was diagnosed in these patients based on the history of established exposure to tick bites, presence of classic signs and symptoms, serology and the response to treatment.
