Abstract:
Hepatitis A is a significant endemic and epidemic disease of global importance. There are few studies on the epidemiology of hepatitis A in Poland. The aim of this study was to investigate the prevalence of the antibodies to HAV (anti-HAV IgG) in children and adolescents living in urban and rural areas. Sera from 377 children were collected: 195 lived in Warsaw and 182 in rural area (voyevodship opolskie). The prevalence of anti-HAV was very low--9.3% and 3.8% respectively. This finding suggest that epidemiological shift from intermediate to low endemicity is possible in Poland and a new policy of prophylaxis hepatitis A may be necessary.

Humoral Immune Responses
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
