ABSTRACT

The State Public Health Laboratory (LESPN) files were revised to analyze the outbreak of dengue during 2007 in Monterrey, N. L. the metropolitan area Ae. aegypti breeding sites were classified to identify positive samples in different containers: small, large boats and 20 L bucket, less than 200 L, 200 L drums, over 200 L, sinks and tanks, aquatic plants, coolers and tires to determine the frequency and larval productivity of each of them. From 3106 (89.66%) positive samples for Ae. eagypti, were determinate 11 575 (96.20%) of larvae. According to the virology analysis, the positive cases were separated by the ELISA serological test, there were divided by type of classic dengue fever (DF) or dengue hemorrhagic fever (DHF), age group and gender, also was considered the date of onset of symptoms as a variable to analyze. From a total of 11,045 serum samples processed for dengue detection, 2829 (25.61%) were positives. There were determined 2341 (82.75%) of classical dengue and 488 (17.25%) from the hemorrhagic. Most cases occurred in women 1610 (56.91%), while 1219 cases (43.08%) occurred in men, the age group most affected was from 11 to 20 old. The highest occurrence in Monterrey was 889 (31.42%), followed by Apodaca 757 (26.76%), San Nicolas de los Garza 568 (20.08%) and Escobedo 348 (12.30%) for a total of 2562 (90.56 %) cases. Using SPSS v15, cross tables were conducted to determine the frequencies number of larvae of Ae. aegypti and containers per month of sampling. Also the same procedure was applied for cases of dengue (DF anf DHF) referring month of symptoms onset, gender and age of the patients.
