Knowledge towards Prevention and Management of Dengue: A Cross-sectional Study among Dental, Medical and Pharmacy Students in a Private University, Malaysia

Aim: The aim and objectives of the study were: 1) To assess the knowledge regarding dengue viral infection among undergraduate healthcare professional (HCP) students. 2) To investigate the association of socio-demographic factors towards dengue knowledge among the study participants. 3) To compare the dengue knowledge among the three HCP (Dental, Medical and Pharmacy) students.

Study Design: A cross sectional study design was used in the study.

Place and Duration of Study: The study was conducted in AIMST University campus, Kedah state, Malaysia between January, 2017 and June, 2017.

Methods: The study was conducted among HCP students using pre-validated questionnaire with knowledge as a single dependent variable. The questionnaire was distributed in class room setting after obtaining informed consent forms signed by participants. The summary statistics for categorical variables was used with chi-square test to see if there was any association between the variables. Inferential statistics was done using Spearmans correlation.

Results: Among the 636 participants, an overall good knowledge (≈90%) was observed regarding the cause, breeding sites and common clinical symptoms of dengue fever. However, poor knowledge was observed regarding the time of dengue mosquitoes bite (51%, P = .58) and transmission through blood transfusion (59%, P <.001). Very poor knowledge was observed regarding transmission through person to person contact (25%, P <.001). The median knowledge score was 12(3) ranging from 0 to 15. There was a statistically significant differences (P < .001) in response to 14/15 knowledge based items. Further, a statistically significant association between dengue knowledge score was observed among field of study (P < .05) and year of study (P < .006) variables. The Spearman's correlation test showed a weak positive correlation [rs(2) = 8.6, P < .01] and [rs(10) = 108, P < .001] between year of study and age categories for dengue knowledge scores.

Conclusion: Overall, the HCP students in AIMST University showed good knowledge score towards dengue however, educational intervention programmes can further enrich their knowledge in the prevention, treatment and management of this deadly disease.
