Methods: A cross-sectional study was performed in February 2015 using secondary data acquired from the hospital records. There were 2607 confirmed dengue cases presented to Hospital Universiti Sains Malaysia (HUSM) in 2014. Seven hundred patients were selected after proportionate stratified random sampling conducted according to the number of cases in 12 different months in 2014. Data were collected and analysed using SPSS version 22.0. Results: Severe dengue outcomes represented 4.9% of cases. The prevalence of any of WS in SD was 91.2%. The most common WSs prior to SD were persistent vomiting (55.9%), and abdominal pain\/tenderness (52.9%). The most sensitive warning sign in detecting SD was abdominal pain (59%). Specificity of individual WS were generally good, especially of clinical fluid accumulation (99%), hepatomegaly (98%) and mucosal bleeding (93%). Factors associated with SD were persistent vomiting (Adjusted odds ratio (aOR)): 2.41), mucosal bleeding (aOR: 4.73) and haematocrit rise with rapid platelet drop (aOR: 2.74). Conclusion: A focus on sensitivity, specificity, predictive values and association of a number of particular WS should be emphasized in order to better predict severe dengue outcomes.<\/jats:p>","DOI":"10.3390\/ijerph15092018","type":"journal-article","created":{"date-parts":[[2018,9,17]],"date-time":"2018-09-17T10:42:20Z","timestamp":1537180940000},"page":"2018","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["The Sensitivity, Specificity and Accuracy of Warning Signs in Predicting Severe Dengue, the Severe Dengue Prevalence and Its Associated Factors"],"prefix":"10.3390","volume":"15","author":[{"given":"Mohd Hanief","family":"Ahmad","sequence":"first","affiliation":[{"name":"Department of Community Medicine, School of Medical Sciences, Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5470-4180","authenticated-orcid":false,"given":"Mohd Ismail","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, School of Medical Sciences, Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeehaida","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Department of Microbiology &amp; Parasitology, School of Medical Sciences, Hospital Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nabilah","family":"Ismail","sequence":"additional","affiliation":[{"name":"Department of Microbiology &amp; Parasitology, School of Medical Sciences, Hospital Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Amiruddin","family":"Abdullah","sequence":"additional","affiliation":[{"name":"Department of Microbiology &amp; Parasitology, School of Medical Sciences, Hospital Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafidah Hanim","family":"Shueb","sequence":"additional","affiliation":[{"name":"Department of Microbiology &amp; Parasitology, School of Medical Sciences, Hospital Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7023-9717","authenticated-orcid":false,"given":"Mohd Nazri","family":"Shafei","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, School of Medical Sciences, Universiti Sains Malaysia, Kubang Kerian, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"936","DOI":"10.1111\/j.1365-3156.2011.02793.x","article-title":"Multicentre Prospective Study on Dengue Classification in Four South-East Asian and Three Latin American Countries","volume":"16","author":"Alexander","year":"2011","journal-title":"Trop.
