    Government Subsidies and Presidential Election Outcomes: Evidence for a Developing Country
    (PERGAMON-ELSEVIER SCIENCE LTD, 2008) Cerda, Rodrigo; Vergara, Rodrigo
    We explore the effects of government subsidies on presidential elections in Chile in 1989-99. We use a panel with three periods (the elections of 1989. 1993, and 1999) and 229 counties. We correct for the potential simultaneity problem deriving front the fact that an incumbent facing a difficult political scenario might react by increasing subsidies to improve his/her electoral performance. Our results indicate that the greater the coverage of these types of programs (i.e., the percentage of people receiving subsidies), the higher the votes for the incumbent. (C) 2008 Elsevier Ltd.

    Modification of pertussis vaccination schedule in Chile, immunization of special groups and control strategies. Commentary from the Consultive Committee of Immunizations of The Chilean Society of Infectious Diseases
    (SOC CHILENA INFECTOLOGIA, 2012) Potin, Marcela; Cerda, Jaime; Contreras, Lily; Munoz, Alma; Ripoll, Erna; Vergara, Rodrigo
    In Chile, an increased number of notifications of cases of whooping cough was detected at the beginning of October 2010, and maintained through 2012. Accumulated cases during 2011 were 2,581 (15.0 per 100,000), which is greater than the number of cases registered during the period 2008-2010 (2,460 cases). On the other hand, the local sanitary authority introduced a modification of pertussis vaccination schedule (starting 2012), which consists in the replacement of the second booster of pertussis vaccine (DTwP, administered to 4-year-old children) as well as diphtheria-tetanus toxoid (dT, administered to second grade scholars) for an acellular pertussis vaccine with reduced antigenic content (dTpa), which will be administrated to first grade scholars. The Consultive Committee of Immunizations considers that the modification is adequate, since it extends the age of protection, reducing at least in theory the infection in older scholars and adolescents who are significant sources of transmission of Bordetella pertussis to infants using an adequate vaccine formulation (acellular pertussis vaccine). The available evidence regarding vaccination in special groups (adolescents and adults, health-care workers and pregnant women) and cocooning strategy are commented.

    Rotavirus genotypes in children with gastroenteritis assisted in two public hospitals from Chile: viral strains circulating in a country without a universal vaccination against rotavirus
    (SOC CHILENA INFECTOLOGIA, 2012) Lucero, Yalda; Mamani, Nora; Cortes, Hector; Pena, Alfredo; Vergara, Rodrigo; O'Ryan, Miguel
    Background: Rotavirus is the main cause of severe gastroenteritis (GE) in children. Two vaccines currently available have proven efficacy against the predominant genotypes. Rotavirus genotypes vary both geographically and/or temporally. Genotype surveillance is important to monitor trends associated or not with vaccine use. Aim: To update information on rotavirus genotypes circulating in two main cities of Chile. Methodology: Between May 2009-March 2010, children < 5y of age receiving medical care for GE in two large hospitals were recruited; none of these children had received rotavirus vaccine previously. Epidemiological information was recorded in an ad-hoc form and stool samples were collected for rotavinis detection by a commercial ELISA. Genotyping was performed by semi-nested RT-PCR. Results: A total of 296/967 samples (31%) were positive for rotavirus, with a peak in November/December mostly in children 7-24 months old (67%). G9P[8] was the predominant genotype (76%), followed for G1P[8] (6%) and G2P[4] (6%) in both cities. Conclusions: Rotavirus caused one third of GE requiring emergency room care and/or hospitalization, mostly in children within an age range susceptible to benefit from rotavirus vaccines. G9P[8], a genotype against which rotavirus vaccines have demonstrated high efficacy, was by far the most frequent rotavirus variant. Continued surveillance in Chile is crucial for providing background information on disease burden and strain diversity before the introduction of rotavirus vaccines.
