Epidemiology of dengue disease in Malaysia (2000-2012): a systematic literature review.

Mohd-Zaki AH, Brett J, Ismail E, L'Azou M - PLoS Negl Trop Dis (2014)

Bottom Line: The epidemiology of dengue disease in Malaysia was characterized by a non-linear increase in the number of reported cases from 7,103 in 2000 to 46,171 in 2010, and a shift in the age range predominance from children toward adults.Several gaps in epidemiological knowledge were identified; in particular, studies of regional differences, age-stratified seroprevalence, and hospital admissions.PROSPERO #CRD42012002293.

ABSTRACT

Unlabelled: A literature survey and analysis was conducted to describe the epidemiology of dengue disease in Malaysia between 2000 and 2012. Published literature was searched for epidemiological studies of dengue disease, using specific search strategies for each electronic database; 237 relevant data sources were identified, 28 of which fulfilled the inclusion criteria. The epidemiology of dengue disease in Malaysia was characterized by a non-linear increase in the number of reported cases from 7,103 in 2000 to 46,171 in 2010, and a shift in the age range predominance from children toward adults. The overall increase in dengue disease was accompanied by a rise in the number, but not the proportion, of severe cases. The dominant circulating dengue virus serotypes changed continually over the decade and differed between states. Several gaps in epidemiological knowledge were identified; in particular, studies of regional differences, age-stratified seroprevalence, and hospital admissions.

Reported dengue disease cases and deaths in Malaysia 2000–2011 [3], [9], [12], [13], [16]–[23].(A) Number of reported dengue disease cases (incidence per 100,000 population shown as numbers for the total cases only). (B) Number of reported deaths. (C) CFRs. The total annual number of dengue disease cases reported in Malaysia increased between 2000 and 2010 and decreased in 2011. Between 2000 and 2010, the incidence rate of dengue disease was consistently high (above 125 per 100,000 population). The majority of dengue disease cases were reported as DF and the ratio of DF to DHF cases remained fairly constant. The number of annual deaths from dengue disease increased between 2000 and 2010. However, after 2000 the CFR for DF+DHF remained fairly constant. CFR, case fatality rate; DF, dengue fever; DHF dengue haemorrhagic fever.

Mentions: The population of Malaysia has risen by 23% since 2000, from 23,495,000 in 2000 to 28,855,000 in 2012 [12]. The total annual number of dengue disease cases reported in Malaysia increased from 7103 in 2000 to 46,171 in 2010, with the incidence rising from 31·6 to 159·7 per 100,000 population. During the period 2002–2010, the incidence rate of dengue disease was consistently high (above 125 per 100,000 population), peaking at 180·0 and 178·0 per 100,000 population in 2007 and 2008, respectively (Figure 3A) [3], [9], [12], [13], [16]–[23]. However, fewer cases were reported in 2011 compared with previous years (19,884 cases, incidence 69·6 per 100,000 population) [12]. Overall, approximately 50% of dengue disease cases in Malaysia were confirmed by laboratory analysis. This percentage varied from 39·6% to 53·0% in the period 2000–2007, the last year for which data were available [9].
