Dengue fever (DF) is a mosquito-borne disease caused by Dengue virus that transmitted by Aedes Aegypti. Some patients may develop Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Globally, more than 40% of the population is currently at risk of Dengue. Approximately 50-100 million cases of DF and 250-500 thousand cases of DHF are reported yearly. The mortality rate of Dengue is 5-10%. In the coastal governorates of Yemen, not only Dengue fever is an endemic but many outbreaks have been reported since 2002. Out of those governorates, Tazi governorate was one of the most affected during 2017, yet, no cases were reported from Taiz city- the capital of Taiz governorate. In November 2018, suspected Dengue outbreak was reported to the Ministry of Health (MoH). This case study is based on a real outbreak investigation conducted at Al Qahirah district in Taiz city. It simulates an outbreak investigation, including descriptive and analytical epidemiology and an implementation of preventive and control measures against Dengue fever. The study is designed for trainees in Field Epidemiology and can be administered in 3 to 4 hours. Although, the case study is used as adjunct training material, it provides the trainees with competencies in investigating an outbreak and analysing data to identify risk factors for dengue outbreak in Yemen using.
General instructions: this case study will be used as an adjunct training material for Novice Epidemiology trainees to reinforce the concepts taught in prior lectures. For this, the facilitator will ideally teach the case study in groups of 16 participants, as follows: participants will take turns reading the case study, usually a paragraph per student, and the facilitator will guide the discussion via giving possible responses to questions. Further, the facilitator may make use of flip charts to illustrate certain points. Additional instructor´s notes for facilitation are coupled with each question in the instructor´s guide to aid facilitation.
Audience: this case study was developed for Novice Field Epidemiology students. Most participants have health care education background, such as medicine, nursing, environmental health, public health, laboratory sciences, biology, and/or health sciences.
Prerequisites: prior to using this case study, participants should have received course lectures on Disease Surveillance and Outbreak Investigation.
Materials needed: Flash drive, Flip charts, Markers, Computers with Microsoft Excel.
Level of training and associated public health activity: Novice - Outbreak investigation
Time required: 2-3 hours
