Chagas disease: from bush to huts and houses. Is it the case of the Brazilian Amazon?

abstract：BACKGROUND:Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE:This study verified the influence of non-parasitic wound infe...
