ABSTRACT
Objective: to identify the risk factors associated to the epidemic of dengue
virus infections occurred at Queretaro, Mexico.
Methods: a case-control study was carried out on 49 cases and 49
controls. The data included: age, sex, residency, schooling, occupation,
clinical data, sources infected with Aedes aegypti, travelling, source of
waters, and protection to water recipients. The protection to door and
windows was investigated. χ
2 test and odds ratio were estimated.
Results: the age group of 20-39 years was the most affected and women
predominated. The Satellite area contributed with 38 cases (77.1 %). The
absence of mosquito nettings on windows had an OR = 1.8, and ignorance
of preventive activities had an OR = 2.8, while the use of insecticides
(OR = 0.30) and mosquito repellents (OR = 0.54) were protective
factors.
Conclusions: the epidemic outbreak in Queretaro confi rmed that
Aedes
aegypti has adapted to greater heights. This fact should alert to the sanitary
authorities to face the possibility of an epidemic outbreak with great
affectation among population.
