Objective: To describe the epidemiological trends during 2015 -2016 of three of the most important arthropod-borne virus infections occurred in the country in recent years: Zika, Dengue and Chikunguña. Materials and Methods: A descriptive study, in which the behavior of these diseases is analyzed from bulletins of the National Institute of Health, during the fifty-two epidemiological weeks of 2016. Results: In 2016, 103.822 cases were reported in the country Dengue (49.9% ♀), 19.566 of Chikunguña (63.3% ♀) and 106.559 of Zika (66.4% ♀). The most affected population was in the range of 25 to 39 years-old, but significant differences in the average age of the three conditions (p<0.05) were observed. Most reports about Zika infection were based on clinical diagnosis. Conclusions: Implementation of mechanisms that allows a better understanding of the etiology and clinical behavior of these diseases by health actors is required.

in both sexes. In our analysis we used descriptive statistics, independent samples t-test. Results: In 1990, standardized mortality in men 45-59 was the highest in fSU (n=15) 358.69/100,000, the lowest rate was found in WE (n=17) 143.67/100,000. It significantly decreased to 244.99/100,000 (-31.70%, n=11) and 50.29/100,000 (-65.00%, n=15) by 2014 respectively (p,0.05). In 1990, standardized mortality in women 45-59 was the highest in fSU (n=15) 99.78/100,000, the lowest rate was found in WE (n=17) 29.06/100,000. It significantly decreased to 56.26/100,000 (-43.61%, n=11) and 9.89/100,000 (-65.97%, n=15) by 2014 respectively (p,0.05). Mortality also decreased significantly (p,0.001) among men (-49.41%) and women (-50.57%) in EE between 1990 and 2014. Conclusions: A significant decline was detected in standardized mortality of IHD in both sexes aged 45-59 between the assessed time period. The highest improvement was observed in Western-European countries.
