Prevalence of Toxocara spp. eggs in soil of public areas in Iran: A systematic review and meta-analysis

Toxocariasis is a zoonotic and widespread infection which manifest as a spectrum of syndromes in humans such as visceral, neural, ocular, covert and asymptomatic. Herein we aimed to design a systematic review and meta-analysis to determine the prevalence of Toxocara spp. eggs in soil depositories in...
