GONZALEZ, María M et al. Seroprevalence of antibodies to measles, rubella, mumps, hepatitis B viruses and all three poliovirus serotypes among children in Quindío, Colombia. Rev. salud pública [online]. 2016, vol.18, n.1, pp.95-103. ISSN 0124-0064.  https://doi.org/10.15446/rsap.v18n1.44514.

Objective The main goal of this research was to assess the seroprevalence of antibodies against measles, rubella, mumps, hepatitis B and all three poliovirus serotypes among children in the Quindío Department, Colombia. Methods Blood samples were obtained from 170 healthy children aged 5-9 years from nine municipalities in Quindío. The presence of serum IgG antibodies against measles, rubella, mumps and Hepatitis B were determined using commercial indirect ELISA kits. Immunity to poliomyelitis was assessed through the presence of neutralizing antibodies following the method recommended by the World Health Organization. Results Among the 170 children enrolled, 169 (99.41%), 170 (100 %), and 167 (98.2 %) were seropositive to poliovirus 1, poliovirus 2, and poliovirus 3, respectively. The average reciprocal antibody titers were 178 for poliovirus type 1, 120 for type 2 and 56 for type 3. Of the 170 children, 96.47 % were protected against mumps and rubella, and 86.47 % against measles. Only 106 (62.35 %) of the studied subjects were proved to be seropositive to hepatitis B. Conclusion The immunization program in Quindío has provided seroprotection against all three poliomyelitis serotypes, rubella and mumps. However, the child population is not fully protected against measles and hepatitis B virus infections.
