biogeographical origin and varicella risk in the adult immigration population in catalonia, spain (2004-2006).immigrants to the european union may have a higher susceptibility to varicella-zoster virus primo-infection than the indigenous population. there is no evidence as yet that this is caused by genetic or social factors. therefore, susceptibility could be due to a lesser transmission of the virus in their ecosystems of origin. a multicentre observational study was performed from july 2004 to june 2006 in four primary healthcare centres in catalonia, spain, monitoring varicella incidences and compar ...200919761736
critical prevalence of antibodies minimizing vaccination costs for hepatitis a, hepatitis b, varicella, measles and tetanus in adults and adolescents in catalonia, spain.the prevalence of seropositive individuals that makes costs of vaccinating all individuals equal to that for screening and vaccination of susceptible individuals is defined as the critical prevalence of antibodies (p*). screening and vaccination is more efficient when the prevalence of seropositive individuals (p) in the population is higher than p*. in this study, the formula to obtain p* was derived from the cost-effectiveness equations, showing that it depends on screening and vaccination cos ...200415364450
estimated varicella incidence on the basis of a seroprevalence survey.varicella is a disease caused by varicella-zoster virus. it is transmitted via the respiratory route, is highly communicable and mainly affects young children. an effective vaccine is now available, whose routine use is advised by health authorities in the usa and which can prevent severe disease, although breakthrough infections do occur. in deciding whether or not to include a vaccine in the routine vaccination schedule, knowledge of the morbidity of the disease in question is fundamental. alt ...200111811884
