PlumX Metrics Dengue is the most prevalent mosquito-borne viral disease in people. In Thailand, the dengue classification is based on the 1997, and 2011 WHO guidelines and is divided into the following phases: 1) fever phase: acute fever onset that is high and continuous, lasting 2–7 days; 2) critical/shock phase: 1/3 of patients in the decreasing fever range. . Fever/ history of fever, lasting for 2-7 days, occasionally biphasic 2. Dengue is known for being the world fastest-spreading infectious mosquito-borne viral illness, 1 which varies itself into four genetically distinct dengue virus serotypes, namely DEN1, DEN2, DEN3, and DEN4, of the genus Flavivirus, and is transmitted by Aedes aegypti and A. albopitus mosquitoes. The 2009 WHO dengue classification was more sensitive than physicians’ clinical diagnosis for identification of acute dengue (71.5% vs 67.1%), but was less specific. Dengue virus infection causes a wide range of clinical manifestations. The 2009 clinical classification has been criticized for being overly inclusive, as it allows several different ways to qualify for severe dengue, and nonspecific warning signs are used as diagnostic criteria for dengue. On the other hand, some reports initiated by a study in the UP Los Banos had produced another suspicious mosquito to be a dengue carrier- known as Aedes Albopictus. Dengue viruses 1 to 4 (DENV1-4) are mosquito-borne flaviviruses that cause 50 to 100 million cases of dengue fever (DF) and ~500,000 hospitalizations annually (1, 2).Dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) is the most severe form of dengue disease and is characterized by vascular leakage, hemorrhagic manifestations, thrombocytopenia, and hypotensive … The classification of dengue virus-infected patients continues to be a challenge to researchers and clinicians in the field. 19 Most cases of dengue in the contiguous states of the United States are travel related, most commonly from the Caribbean, Pacific Islands, Asia, and Central and South America.

Dengue is classified as dengue with or without warning signs and severe dengue. Differentiation between classic dengue fever (DF) and dengue haemorrhagic fever (DHF) or severe dengue is a key aspect of dengue case classification. The geographic expansion of dengue and its increased incidence in older age groups have contributed to the limited applicability of the 1997 case definitions. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. 2011 Feb. 84(2):224-8. .

The classification has been criticized with regard to its usefulness and its applicability. Several studies reported lack of correlation between the categories of the conventional classification and the disease severity. The new classification guidelines was created 2011 and implemented last 2012 and is still not widely used. 2011. pp. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. WHO, in its recent dengue guidelines 2009, has alluded to the fact that its existing classification into dengue fever and dengue hemorrhagic fever (further divided into 4 grades) have a number of limitations due to the rigidity of its criteria. For patients to be classified as dengue fever (probable), the pre-criteria is that any patients living in or travelling ENDEMIC AREA for dengue (including Malaysia) AND with FEVER and with 2 out of the following criteria: Nausea, vomiting Rash Aches and pains Tourniquet test positive Leukopenia Any warning sign One palpable benefit of the new classification is the reduction of dengue deaths in the Americas, with approximately 3,300 deaths prevented between 2011 and 2014.

A prospective study of suspected dengue patients admitted to the Dengue Unit, Queen Sirikit National Institute of Child Health between June-August 2009 was done. Dengue classification according to the World Health Organization guidelines issued in 2009. This classification has higher sensitivity than the 1997 classification to identify patients with severe dengue that would require intensive care [Reference Alexander 35– Reference Macedo 37]. Dengue viruses have spread rapidly within countries and across regions in the past few decades, resulting in an increased frequency of epidemics and severe dengue disease, hyperendemicity of multiple dengue virus serotypes in many tropical countries, and autochthonous transmission in Europe and the USA. However, in 2000, the Brazilian MoH proposed the DCC classification, to define severe dengue cases that did not meet the WHO criteria for DHF/DSS. However, as of publication of this post, the old classification is still under use by Philhealth and some hospitals. Am J Trop Med Hyg. The presence of effusion, presence of bleeding, and platelet counts are also clinical outcomes of dengue haemorrhagic fever, which could affect the associations between these three prognostic factors and progression to severe disease. 2011).

World Health Organization Regional Office for Southeast Asia. Current WHO classification is recommended for continuing use because the newly suggested TDR classification creates about 2 times the workload to health care personnel. It classifies dengue disease as Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF), and Dengue Shock Syndrome (DSS). The accuracy of the 1997 World Health Organization (WHO) dengue case definition has been debated for a decade, because the definition was very stringent, for instance, several researchers showed that apparently severe cases were misclassified as not severe. According to the 2009 classification, 100% (121/121) of the cases were classified as severe dengue. Probable Dengue. Dengue is a febrile illness caused by infection with one of four dengue viruses (DENV) transmitted by Aedes aegypti or Aedes albopictus mosquitoes during the taking of a blood meal [ 1-3 ]. A major drawback of the 1997 dengue classification is that it focuses mainly on Discovery Proteomics and Nonparametric Modeling Pipeline in the Development of a Candidate Biomarker Panel for Dengue Hemorrhagic Fever. dengue case classification and level of severity Dengue illness is categorized according to level of severity as dengue without warning signs, dengue with warning signs and severe dengue. According to the WHO 1997 classification, 9.1% (11/121) of the cases were classified as dengue hemorrhagic fever (DHF) and 3.3% (4/121) as dengue shock syndrome. Dengue is found in tropical regions around the world, predominately in urban and peri-urban areas. 2006;368:170-73. classification of dengue cases was proposed in 2009 by the WHO.
