| Summary: | Abstract: Exanthematic diseases are a group of pathologies caused by viral agents, which appear frequently during the first years of life and respond in greater proportion to infections caused by viruses, such as measles, varicella (chickenpox), rubella (German measles) and dengue, among others. The objective of this study is to evaluate immunity to measles and chickenpox viruses in children and adolescents residing in the Páez municipality, state of Zulia, Venezuela. Without regard to sex, 174 samples from apparently healthy adolescents and children between 8 and 17 years old were studied and analyzed using the ELISA technique. A frequency of 59.7% was detected for the measles virus and 44.8% for varicella. Seroprevalence for measles and varicella was distributed homogeneously in all age groups. For both diseases, greater frequency was observed in males, without significant differences. The study demonstrated low immunity to these viruses and suggests increasing vaccination programs in this municipality to eliminate circulation of these infectious agents in the population. Resumen: Las enfermedades exantemáticas son un grupo de patologías causadas por agentes virales, que se presentan frecuentemente sobre todo durante los primeros años de vida y responden en su mayor proporción a infecciones causadas por virus como sarampión, varicela, rubéola y dengue, entre otros. El objetivo de este estudio fue evaluar la inmunidad a los virus de sarampión y varicela en niños y adolescentes, residentes del municipio Páez del estado Zulia, Venezuela. Se estudiaron 174 muestras provenientes de escolares y adolescentes aparentemente sanos, sin distingo de sexo y en un rango de edad comprendido entre 8 a 17 años, las cuales fueron analizadas mediante la técnica de ELISA. Se detectó una frecuencia de 59,7% para el virus del sarampión y un 44,8% para varicela. La seroprevalencia para sarampión y varicela estuvo homogéneamente distribuida en todos los grupos etarios. En ambas enfermedades se observó una mayor frecuencia en el sexo ... |
