Abstract. The co-circulation of all 4 dengue virus serotypes in the same community, common since the 1950s in Southeast Asia, has now become a frequent occurrence in many Caribbean Islands, Mexico, and Central and South America in the past 20 years. As a consequence, the frequency of concurrent infections would be expected to increase in these areas. To assess this, using state of the art technology, we screened viremic serum samples and mosquitoes inoculated with serum samples collected during epidemics involving multiple dengue virus serotypes in Indonesia, Mexico, and Puerto Rico for virus isolation. Of 292 samples tested, 16 (5.5%) were found to contain 2 or more dengue viruses by an indirect immunofluorescence test and/or the reverse transcriptase-polymerase chain reaction.The global epidemiology of dengue/dengue hemorrhagic fever (DF/DHF) has changed dramatically in the past 50 years, first in Southeast Asia during and following World War II, and in the past 20 years in other tropical regions of the world, especially in the Americas.

The manuscript presents results of research conducted with the aim of analyzing the association of geographic areas and risk factors of violence to women occurred in the state of Yucatan during 1997-2014, by reviewing statistics and other sources. Variables domestic violence, sex crimes and homicides and femicides association and risk according to the degree of marginalization, town size and percentage of population analyzed Maya. The main findings of the research show the presence of violence in 49 of the 106 municipalities. Association found the urban condition in cases of domestic violence, sexual offenses, homicide, and femicide, while for domestic violence it was obtained that the condition of Maya speakers is a risk factor. The geospatial distribution shows areas of high violence mostly in the south and east of the state. Some municipalities' rates for homicide and domestic violence, are higher compared to the national and state average rates recorded. It is concluded that information management has been the key to catalog the state as low gender violence and that the results presented here show the presence of large geographical areas of high risk for the lives of women, which requires your attention of inter-sectoral public policy.
