From 1968, tetanus vaccination became necessary for those newborns. ELISA kit. Subjects were stratified by age and by WHO region. Antibody titers 0.10 PF-05085727 IU/ml were considered to be seronegative, between 0.10 and 1.00 IU/ml as intermediate protection, and 1.00 IU/ml high protection. Results: From January 2004 to December 2019, 2,326 blood samples were collected. Mean age was 13.9 years with no differences between WHO regions. The percentage of the subjects without protecting antibodies was 22.3%, with an ADAMTS1 intermediate level was 45.2%, with high titer was 32.5%. Among migrant coming from African and Eastern Mediterranean WHO areas, the highest percentages of seronegative titers and, at the same time, the low percentages of high protecting levels were found. Titers decreased with age. Conclusions: The significant proportion of seronegative migrants and the decrease of protecting titers increasing age, confirm the importance of the evaluation of the immunological status PF-05085727 to employ the appropriate vaccination strategy. strong class=”kwd-title” Keywords: tetanus, migrants, serological survey, seroprevalence, immunity, WHO region Introduction Tetanus is one of the rare diseases that is infectious but not communicable. Immunity to tetanus toxin is definitely induced only by immunization, so the recovery from medical tetanus does not result in safety against further attacks. On the contrary to what happens for diseases transmitted from person to person, the achievement of high vaccination protection in children does not allow to obtain an indirect protecting effect in the population. Therefore, tetanus can never be eradicated because it is definitely impossible to remove spores from your ground and generally from your living environment (1-5). The vaccine against tetanus allowed massive progress in controlling the disease. The epidemiology of tetanus offers radically changed due to the availability of a highly effective vaccine since the 1930s. Tetanus became sporadic in several high-income countries, where well-established child years primary immunization programs have made a major contribution in the drastic reduction in morbidity and deaths (6, 7). In these countries, however, most instances happen among unvaccinated elderly people (8-10). A serosurvey study of six European countries in 2015 showed that 2C31% of people aged 65 experienced subprotective antitetanus toxin antibody concentrations (11). The disease remains an important general public health problem in many parts of the world, particularly in low-income countries, where most of reported tetanus instances are birth-associated, as result of the unclean deliveries and umbilical wire care methods (6, 7). Moreover, these instances are signals of inequity in access to immunization and to additional maternal, newborn, and child health solutions (12, 13). The Maternal and Neonatal Tetanus Removal (MNTE) initiative, i.e. a reduction of the incidence below one case for 1000 live births per area, over 1 year, is the common goal in all countries of the world (14, 15). As of September 2019, 47 out of 59 countries identified as high-risk for maternal and newborn tetanus experienced fully eliminated the disease and over 154 million ladies were immunized against tetanus between 1999 and September 2019. However, 12 countries remain to be validated, of which 11 are in the African and Eastern Mediterranean areas (16). During 2017, 82 tetanus instances were reported in 26 countries of the European Union (EU), having a notification rate of 0.02 cases per 100,000 population that is in the range reported since 2012. Italy together with Poland accounted for 54% of all notified instances. Italy, albeit having a sluggish and progressive reduction over the years, remains, at Western level, the country with the highest number of cases, with an annual notification rate that remained stable PF-05085727 between 0.08-0,1 /100,000 from 2013 to 2017. Of the 231 instances reported in Italy in this period, 78% occurred in the age group 65 years old and above (8-10, 17). In Italy, tetanus toxoid.
