To know the prevalence of malaria and the factors associated with the infection in migrants in the southern border of Mexico, during 2008.
In 706 migrants, active malaria infection was investigated using a rapid diagnostic test and PCR and past infection using serology. A questionnaire was applied to investigate the conditions associated to infection.
85.6% originated from Central America, none presented an active infection, although 4.2% were seropositive, most of these came from the countries with the highest malaria incidence in the region. Seropositivity was associated with the number of previous malaria episodes (OR=1.44; IC95% 1.04-2.00), years living in their community of origin (OR=1.03; IC95% 1.00-1.07), and knowledge and self-medication with anti-malaria drugs (OR=3.38; IC95% 1.48-7.67).
. The previous exposure of migrants and the difficulties for their detection indicate the need of new strategies for the epidemiological surveillance for these populations.
了解2008年墨西哥南部边境地区移民中疟疾的流行情况以及与感染相关的因素。
对706名移民进行调查，采用快速诊断试验和聚合酶链反应检测活动性疟疾感染，采用血清学方法检测既往感染情况。应用问卷调查与感染相关的情况。
85.6%的移民来自中美洲，无人有活动性感染，尽管4.2%的人血清学呈阳性，其中大多数来自该地区疟疾发病率最高的国家。血清学阳性与既往疟疾发作次数（比值比=1.44；95%可信区间1.04 - 2.00）、在原籍社区居住的年限（比值比=1.03；95%可信区间1.00 - 1.07）以及对抗疟疾药物的了解和自我用药情况（比值比=3.38；95%可信区间1.48 - 7.67）有关。
移民既往接触疟疾以及检测他们存在困难，这表明需要针对这些人群制定新的流行病学监测策略。
