Abstract:
In the period 1997-2000 3968 samples were examined. Parasitological material came from 3 174 children and 794 adults. Infection with intestinal protozoan and helminthes was noted in 80.2% of children as well as in 18.5% of adults (to 65 year old) and in 1.3% of patients over 65 year old. Among the children the most often were eggs of Enterobius vermicularis (detected by tongue depressor covered with a transparent adhesive tape) and Giardia lamblia (diagnosed on the detection of coproantigens GSA 65--commercial kits). Every year the detection of G. lamblia in children was the highest in the autumn-winter months what proved the summer infections. E. vermicularis occurred more often than G. lamblia however without the seasonal peaks.
Insights
Intestinal protozoan and helminth infections are common in children, with Enterobius vermicularis and Giardia lamblia being most prevalent. Giardia lamblia showed seasonal patterns, indicating summer infections in children.
Area of Science:
- Medical Parasitology
- Pediatric Infectious Diseases
- Public Health
Context:
- A study examined 3,968 samples from children and adults between 1997-2000.
- Prevalence of intestinal protozoan and helminth infections was assessed in different age groups.
Purpose:
- To determine the prevalence and common species of intestinal parasites in a pediatric and adult population.
- To investigate potential seasonal variations in the detection of specific parasites like Giardia lamblia.
Summary:
- 80.2% of children, 18.5% of adults (≤65 years), and 1.3% of adults (>65 years) were infected.
- Enterobius vermicularis and Giardia lamblia were the most frequent infections in children.
- Giardia lamblia exhibited higher detection rates in autumn-winter, suggesting summer transmission.
Impact:
- Highlights the significant burden of intestinal parasitic infections in children.
- Provides insights into the epidemiology of Enterobius vermicularis and Giardia lamblia.
- Informs public health strategies for parasite control, particularly in pediatric populations.
