[Seroepidemiological Investigations on the epidemiology of human rotavirus infections (author's transl)]
Insights
Maternal antibodies against Nebraska calf diarrhoea virus (NCDV) disappear in the first year. Most children develop NCDV antibodies by age two, a prevalence sustained throughout childhood.
Area of Science:
- Virology
- Immunology
- Pediatrics
Context:
- Nebraska calf diarrhoea virus (NCDV) is antigenically related to human rotavirus.
- Infant and child sera up to 10 years of age were analyzed.
- Antibody titers were assessed across different age groups.
Purpose:
- To investigate the presence and prevalence of antibodies against NCDV in children.
- To determine the age-specific antibody response to NCDV.
- To understand the role of maternal antibodies and early-life infections.
Summary:
- Antibodies of maternal origin were cleared within the first year of life.
- Significant NCDV antibody acquisition occurred during the second year of life.
- By the end of the second year, 40-50% of children had NCDV antibodies, a level maintained thereafter.
Impact:
- Provides insights into the epidemiology of NCDV infections in children.
- Highlights the age-related pattern of rotavirus-related viral infections.
- Informs potential public health strategies for managing viral gastroenteritis in pediatric populations.
Abstract:
263 sera of infants and children up to 10 years of age were tested for antibodies (CF-test) against Nebraska calf diarrhoea virus (NCDV) which is antigenically related to the rotavirus of man; in addition the mean antibody titers in different age groups were investigated. Antibodies of maternal origin were eliminated during the first year of life. Most of the infections occurred during the second year of life and at the end of this year 40-50% of the investigated children demonstrated antibodies against NCDV; this frequency persists during the rest of the investigated life period.
