Introduction. Plague is a zoonotic infection caused by the bacterium Yersinia pestis, whose recent outbreak since 2009 at La Libertad region has increased the need to reassess the factors associated with transmission. objective. To determine the association between overcrowded in housing and suspected plague cases registered in the district of Casa Grande, La Libertad between 2010 and 2012 (CG-LL 2010-12). Material and Method. The sample size was 11 suspected cases of plague recorded in the district of CG-LL 2010-12 ("Casa Grande" Health Center, Ministry of Health), using a case / control ratio of 1: 2, using random sampling. Overcrowded in housing was evaluated by reviewing epidemiological records in the suspected cases of plague and through a field trip survey of housing data in the controls. Results. We found that the odds ratio of overcrowded in housing was 1,41 with a 95 % confidence interval: 1,10 to 5,66 (p < 0,05). With a overcrowded in housing frequency of 18,18 % in the cases group and 13,63 % in the controls group. Conclusion. Overcrowded in housing was associated 1.41 times more in the suspected plague cases registered in the district of Casa Grande, La Libertad between 2010 and 2012, compared to population who did not contract this disease.
