Toxocariasis in children: seroprevalence after 15 years in a major city in Brazil
<i>Toxocara</i> seroprevalence in children living in an urban area did not significantly change over the 15 years since the previous serosurvey was conducted. As no mitigatory actions were carried out between the surveys, we speculate that environmental contamination and child exposure to <i>Toxocara</i> spp. remained steady. However, future surveys should include soil detection of <i>Toxocara</i> spp. to fully establish the role of environmental contamination over time. In conclusion, although toxocariasis in children may not increase over time, such seroprevalence may not decrease either, persisting (even in low levels) for long periods.
