Aim: To assess the knowledge and attitude of senior medical, dental, nursing and pharmacy students toward Middle East respiratory syndrome-corona virus (MERS-CoV) in Saudi Arabia. Subjects and methods: A cross-sectional survey using a 21-item questionnaire was conducted for a 3-month period from November 2015–January 2016 in Makkah, Saudi Arabia. The questionnaire was designed to evaluate students’ understanding and perception of MERS-CoV. An ANOVA test was used to determine the association of study discipline and academic year with the student knowledge score on MERS. Results: A total of 364 students were assessed during the study. The majority (62%) of the participants were in the 20–22-year age group. More than half (53%) were pharmacy students followed by (22%) medical students. More than two thirds (71%) of the participants were aware that MERS is caused by the coronavirus. More than half (59%) of the participants believed that MERS can be transmitted through direct or indirect contact with infected camels. A statistically significant association was reported between the study discipline and mean knowledge score (p < 0.0001) with medical students achieving an overall better knowledge score compared with students from other study disciplines. Conclusion: Overall, students had good knowledge about MERS epidemiology, transmission and the recommended protective measures. However, students expressed their reluctance to work in healthcare facilities with inadequate MERS infection control isolation policies.
