Vector-Borne Diseases and Associated Factors in the Rural Communities of Northwest Ethiopia: A Community-Based...

Human illnesses caused by parasites, viruses, and bacteria that are transmitted by vectors are called vector-borne diseases. Vector-borne diseases usually affect the poorest populations, particularly where there is a lack of access to adequate housing, safe drinking water, and sanitation. This community-based cross-sectional study was, conducted to assess the prevalence of self-reported vector-borne diseases and associated factors in the rural communities of northwest Ethiopia.

A community-based cross-sectional study design with structured observation was conducted among 1191 randomly selected rural households in northwest Ethiopia from April to June 2017. Data were collected by using a structured questionnaire; and observation checklist. Multivariable binary logistic regression analysis was used to identify variables associated with the prevalence of self-reported vector-borne diseases on the basis of adjusted odds ratio (AOR) with 95% confidence interval (CI) and P-values <.05.

In the current study, 216 (18.1%) of the rural households reported one or more vector-borne diseases. Scabies (9.5%) were the most reported vector-borne disease followed by Malaria (6.9%). The prevalence of self-reported vector-borne diseases was statistically associated with the head of the family (mother) (AOR = 0.13, 95% CI = 0.02-0.72), regular cleaning of the living environment (AOR = 0.51, 95% CI = 0.36-0.74), poor cleanness of the living rooms (AOR = 1.77, 95% CI = 1.03-3.03), and moderate cleanness of the floor (AOR = 1.64, 95% CI = 1.06-2.52).

The prevalence of self-reported vector-borne diseases was high in the rural communities of northwest Ethiopia. The low prevalence was associated with family head; regular cleaning of living environment and cleanness of the floor. Designing and strengthening an intervention strategy for environmental sanitation, regular cleaning of living house, and keeping personal hygiene shall be considered.
