Review of Toxocariasis at a Children's Hospital Prompting Need for Public Health Interventions.

BACKGROUND: Toxocariasis, caused the by dog and cat roundworm, is one of the most common zoonotic helminth infections in the United States and can lead to severe lifelong morbidity in children. Although historical seroprevalence studies have identified a high frequency of toxocariasis regionally in the United States, there are few studies linking epidemiology and clinical disease in children. The study objective was to examine the contemporary epidemiology of pediatric toxocariasis within an endemic US region. METHODS: We conducted an epidemiologic study analyzing children diagnosed with toxocariasis presenting to a tertiary pediatric hospital in Texas from 2010 to 2021. We examined risk factors and performed a geospatial analysis, including a comparative analysis of human cases and locations of surrendered infected stray animals in the same region. RESULTS: Children diagnosed with toxocariasis were most commonly of Hispanic/Latino ethnicity (30/46; 65%), white race (41/45; 91%) and receiving Medicaid (34/44, 77%). Many infected children had contact with dogs or cats. Ocular toxocariasis was associated with a lack of peripheral eosinophilia ( P < 0.001). No other Toxocara syndromes were associated with defined absolute eosinophil count levels. Post-treatment resolution of eosinophilia was variable, ranging from 1 to 172 weeks. A Toxocara hotspot was identified in northeast Houston, comprising one of the lowest median household incomes in the region. CONCLUSIONS: Toxocariasis is a devastating zoonotic infection in children living in the US. As it is not a reportable disease, the true burden remains unknown. It is critical to increase awareness of toxocariasis to direct public health interventions and ultimately reduce Toxocara -induced morbidity in US children.

The Effect of Vaccine Hesitancy on Racial and Ethnic Minority Children During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) outbreak has ravaged the world, with numerous cases disproportionally attributed to the United States due to vaccine hesitancy. One vulnerable group that has been affected by vaccine hesitancy is the pediatric population, particularly those in racial and ethnic minority groups. To improve health outcomes and vaccination rates, we must first understand the factors contributing to vaccine hesitancy and its subsequent influence on the pediatric population. The medical community can better tailor public health strategies by analyzing historical and current events contributing to COVID-19 vaccine hesitancy. A comprehensive approach will improve the health of children and society as a whole. [Pediatr Ann. 2022;51(3):e107-e111.].
