Summary
This study tracked 77 children for Toxocara spp. infection seroconversion, finding an incidence of 10.4% per year. Asthma was significantly associated with developing this parasitic infection.
Area of Science:
- Medical Parasitology
- Epidemiology
- Pediatric Health
Background:
- Toxocara spp. infection is a widespread zoonotic parasitic disease.
- Previous research on toxocariasis, particularly its association with asthma, has primarily relied on cross-sectional study designs.
- Understanding the incidence of Toxocara spp. infection seroconversion is crucial for public health assessments.
Purpose of the Study:
- To estimate the incidence of seroconversion for Toxocara spp. infection in a pediatric cohort.
- To identify variables associated with Toxocara spp. infection seroconversion.
- To provide incidence data for Toxocara spp. infection, contributing to the understanding of its epidemiological burden.
Main Methods:
- A cohort study involving 77 children aged 2-12 years with initial negative serology for Toxocara spp.
- Univariate, bivariate, and logistic regression analyses were employed to examine socioeconomic, behavioral, and health variables.
- Seroconversion for Toxocara spp. infection served as the primary outcome measure.
Main Results:
- The incidence of seroconversion for Toxocara spp. infection was determined to be 10.4 per 100 person-years.
- Asthma emerged as the sole independent variable significantly associated with seroconversion, exhibiting an odds ratio of 3.57 (95% CI: 1.01-12.6).
Conclusions:
- This study provides novel incidence data for Toxocara spp. infection seroconversion in children.
- The findings highlight a significant association between asthma and the development of Toxocara spp. infection.
- This research underscores the importance of considering parasitic infections in the context of pediatric respiratory conditions.

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
