Prevalence of Bed Bug Infestation (Cimex lectularius) in Prisons in Mazandaran Province, 2015-2017

Abstract

Background and purpose: Bed bugs (Cimex lectularius) are major human ectoparasites. Before planning and implementation of any control measures against bed bugs in prisons, it is essential to determine the infestation rate. Materials and methods: This descriptive cross-sectional study was performed to determine the prevalence of bed bug infestation in prisons in Mazandaran Province, 2015-2017. A standard checklist was prepared based on the health log of the prisons and was used to collect information on prevalence of bed bugs. Data were analyzed using SPSS V20. Results: The highest rate of infestation (68%) was observed in general ward and the lowest was seen in women's ward (1.23%). Highest infestations were reported at nights (88%) and the highest numbers of bed bugs were collected in metal beds (31%). During three years, there were no reports of bed bugs and their bites in prison 6. The average prevalence was constant in prison 1, while it was descending in prisons 2, 3, 5, and 9 and ascending in prisons 4 and 8. Conclusion: High prevalence of bed bugs in most of the prisons in Mazandaran province could probably be due to their entry into the prisons, re-infestation, and also difficulties in their control. Therefore, continuous monitoring of infestation, monitoring and prevention of bed bugs gaining entry into prisons, revising control measures with collaboration between experts from the Ministry of Health and prison health services are essential to plan for successful bed bug control interventions.
