RESUMO
INTRODUCTION: An increase in whooping cough in most of the developed countries has been detected in the last decade. OBJECTIVE: To determine whether the administration of dTpa vaccine instead of DTPa fifth dose is contributing to the appearance of these cases. METHODS: A descriptive study based on cases of whooping cough reported during an epidemic period in the city of Alicante in the first 5 months of 2014. Only pertussis cases confirmed by PCR were included in the study, and only those vaccinated with 5 doses were included in the analysis of the period of protection. RESULTS: A total of 104 cases of pertussis confirmed by PCR were reported, with 85 cases (82%) having had 5 doses of vaccine. The mean time and standard deviation (SD) of protection was 2.1±1.1 years with dTpa, and 5.1±1.5 years with DTPa (p<.001). In the protection, adjusted for age, it was observed that, after 3 years, only 47.6% of people vaccinated with dTpa were still protected, while people vaccinated with DTPa were 100% protected (P<.001). CONCLUSIONS: This study found that people who were properly vaccinated against pertussis and received their last re-vaccination dose with dTpa had a shorter period of protection than those who were vaccinated with DTPa.

OBJECTIVE: The increase in morbidity and mortality associated the influenza virus infections represents an important global challenge, with particular relevance within health institutions.The aim of the study was to highlight the impact, repercussions and characteristics of the nosocomial transmission of influenza virus. METHODS: A sample of 286 hospitalized patients in a third-level hospital with confirmed influenza (virus RNA in respiratory specimens) is included. The study design was observational, through the collection of positive microbiological results from the 2016-2017 season. A comparative statistical analysis was carried out between cases of community-acquired influenza and hospital-acquired cases. RESULTS: 14.3% of the total sample (41 cases) was considered of nosocomial origin. Significant differences were observed in the percentage of vaccinated between hospital-acquired (34.1%) and community-acquired (50.2%); and in the number of days of hospitalization after diagnosis between both groups. The attack rate was 0.66%. CONCLUSIONS: The nosocomial acquisition of the influenza virus resulted in a greater severity of the process and in the increase of days of hospital stay. Strict adherence to control measures and epidemiological surveillance of influenza cases has allowed to reduce the attack rate.
OBJETIVO: El incremento de la morbimortalidad asociado a la infección por el virus de la gripe supone un importante reto a nivel mundial, con especial relevancia dentro de las instituciones sanitarias. El objetivo del estudio fue analizar el impacto, repercusiones y características de la transmisión nosocomial del virus de la gripe. METODOS: Se incluyó una muestra de 286 pacientes hospitalizados en un centro de tercer nivel con gripe confirmada (ARN del virus en muestras respiratorias). El diseño del estudio fue observacional, mediante recogida de los resultados microbiológicos positivos de la temporada de gripe 2016-2017. Se realizó un análisis estadístico comparativo entre los casos de gripe comunitaria y los casos nosocomiales. RESULTADOS: El 14.3% del total de la muestra (41 casos) se consideró de origen nosocomial. Se observaron diferencias significativas en el porcentaje de vacunados entre los casos de infección nosocomial (34,1%) y comunitaria (50,2%), y en el número de días de ingreso tras diagnóstico (12 ±22 días para los casos nosocomiales y 6 ±8 días para los comunitarios). La tasa de ataque fue del 0,66%. CONCLUSIONES: La adquisición nosocomial del virus de la gripe se tradujo en una mayor gravedad del cuadro y en el incremento de los días de estancia hospitalaria. El estricto cumplimiento de las medidas de control y vigilancia epidemiológica de los casos de gripe ha permitido lograr una tasa de ataque reducida.

The objective was to evaluate the healthcare personnel seasonal influenza immunization program in the 2011-2012 flu season. The campaign included several innovative actions (informational brochure, recommendations for unvaccinated staff to wear a mask, acknowledgement letters, etc). Coverage and characteristics of the health personnel were compared with the previous season using the chi-square test. Vaccination coverage for the 2011-12 flu season was 26.5%, compared to 24.5% achieved in 2010-2011 (p=0.052). The improvement in vaccination coverage approached statistical significance but remains very low. To improve these low vaccination levels, we recommend developing other strategies, such as incentive policies or making vaccination mandatory.
El objetivo del trabajo ha sido evaluar el programa de vacunación antigripal en personal sanitario en la temporada 2011-2012. La campaña incluyo actuaciones novedosas (tríptico informativo, recomendación de utilizar mascarilla en no vacunados, cartas de agradecimiento, etc.). Se comparó la cobertura y las características de los profesionales vacunados con la de la temporada previa con la prueba de la Ji cuadrado. La cobertura vacunal en la temporada 2011-2012, fue del 26,5%, frente al 24,5% del 2010-2011 (p=0,052). La mejora encontrada en la cobertura vacunal está en el límite de la significación estadística pero sigue siendo muy baja. Para mejorar las bajas coberturas vacunales, habría que plantearse otro tipo de estrategias, tales como políticas de incentivos o de obligatoriedad.
