Resumo: The seroprevalence of hepatitis B was investigated in over 12 000 subjects in six countries of Latin America: Argentina, Brazil, Chile, the Dominican Republic, Mexico, and Venezuela. Each study population was stratified according to age, gender, and socioeconomic status. Antibodies against hepatitis B core antigen (anti-HBc) were measured in order to determine hepatitis B infection. The highest overall seroprevalence was found in the Dominican Republic (21.4%), followed by Brazil (7.9%), Venezuela (3.2%), Argentina (2.1%), Mexico (1.4%), and Chile (0.6%). In all the countries an increase in seroprevalence was found among persons 16 years old and older, suggesting sexual transmission as the major route of infection. In addition, comparatively high seroprevalence levels were seen at an early age in the Dominican Republic and Brazil, implicating a vertical route of transmission.

Cada una de las poblaciones estudiadas fue estratificada por edad, sexo y nivel socioeconómico. Se hicieron determinaciones de anticuerpos contra el antígeno nuclear del virus de la hepatitis B (anti-HBc) con el fin de detectar la infección. La seroprevalencia general más alta se encontró en la República Dominicana (21,4%), seguida del Brasil (7,9%), Venezuela (3,2%), Argentina (2,1%), México (1,4%) y Chile (0,6%). En todos los países se encontró un aumento de la seroprevalencia en personas de 16 años de edad o mayores, lo cual indica que la transmisión sexual es la principal fuente de infección. También se hallaron tasas de seroprevalencia elevadas en personas jóvenes en la República Dominicana y el Brasil, fenómeno que apunta hacia la vía de transmisión vertical.application/pdfengRevista panamericana de salud pública.
