Resumen El virus del papiloma humano es una infeccion de transmision sexual con un alto indice de contagio en poblacion joven y adulta y principal factor del cancer cervico-uterino ligado al inicio precoz de las relaciones sexuales. Objetivo Determinar el nivel de conocimientos de adolescentes de una escuela preparatoria, sobre el virus del papiloma humano. Metodos Estudio transversal, descriptivo realizado en 242 alumnos de ambos sexos. Se aplico instrumento con 46 items agrupados en cuatro secciones: datos sociodemograficos, conocimientos sobre el virus, aspectos de salud sexual y fuentes de informacion; nivel de confiabilidad de 0,7. Resultados Un 53.7% mujeres, 40.5% con 17 anos y un 97.1% soltero. El 64.6% no identifico que es el virus del papiloma humano, El 68.6% no supo que afecciones puede generar el virus, y el 88% no identifica que el fumar puede predisponer, en las mujeres, riesgo para la adquisicion del virus; el 78.5% identifico el factor principal de riesgo y el 82.6% la mejor via de proteccion contra la infeccion. El nivel de conocimientos general fue bajo en el 80% de los participantes. Conclusiones El desconocimiento frente al fenomeno puede contribuir a la mala praxis en salud o a tener actividades riesgosas como el tener multiples parejas sexuales o no usar el preservativo ante un contacto sexual.

The problems of air pollution became noticeable in Cartagena in the seventies, high SO2 and particle levels having been reached from time to time. Our aim is to assess, using the EMECAM methodology, the acute impact of SO2 and particle air pollution on the daily death rate of the city of Cartagena in the 1992-1996 period.A daily listing is provided of the total number of non-accidental deaths within the population as a whole and for those over age 70, the cardiovascular and the respiratory deaths due to dioxide and particle air pollution for the 1992-1996 period using autoregressive Poisson models which control seasonality, weather, time of year, flu, special events, and time lags.In the period under study, there has been a drop in the SO2 air pollution as compared to previous years, which was not as marked for the particles. The analyses reveal significant relationships in the total non-accidental deaths in those over age 69, with the average particle count and those particles with cardiovascular deaths for the months of May to October. In the six-month period of the year, when the weather is cold, we found a positive statistically significant relationship to exist in the maximum daily hourly value of the particles and the deaths due to cardiocirculatory and respiratory diseases. However, there is no consistency in the between on assessing the reliability of the models.
