Dengue in Dhaka, Bangladesh: Hospital-based cross-sectional KAP assessment at Dhaka North and Dhaka South City Corporation area

Abstract

Dengue, the most important mosquito-borne viral disease of humans is a recurring global health problem. In Bangladesh, dengue outbreaks are on the increase despite the efforts of government and it is not clear what the understanding of the general Dhaka population towards dengue fever is. Knowledge, attitude and practice (KAP) studies are essential guides in public health interventions. Hence, using KAP, this study aims to assess patient-perspectives with regards to factors associated with dengue, as well as investigate the associated factors between the two corporations in Dhaka. A Hospital-based cross-sectional study of 242 fever patients from two city-corporations in Dhaka (Dhaka North City Corporations, DNCC (n = 91, 37.6%) and Dhaka South City Corporation, DSCC (n = 151, 62.4%) was conducted using pre-tested KAP items. Wilcoxon’s Rank Sum was used to determine the KAP by DNCC, DSCC and both corporations and multivariate Poisson regression analyses. The two corporations were analysed separately due to the differences in income distribution, concentration of slums, hospitals and clinics. The study found that more than half of the study population were knowledgeable about dengue (mean percentage scores was 52%), possess an appropriate and acceptable attitude towards the disease (69.2%), and about two thirds of the respondents (71.4%) engaged in practices towards its prevention. After adjusting for the potential cofounders, the factors associated with KAP about dengue fever varied between DNCC and DSCC; with duration of residency and use of mosquito nets were associated with knowledge in the north while income class and age were associated with knowledge and attitude in the south. In the pooled analysis (combining both corporations), knowledge of dengue was associated with good practice towards dengue fever among the respondents. The duration of residence in Dhaka (10+ years), not using mosquito nets and length of time spent in the hospital (7+ days) due to dengue, and decreased knowledge (Adjusted coefficient (β) = -0.01, 95%CI: -0.02, -0.01) were associated with attitude towards dengue in DNCC. On the other hand, middle-high income class, age (40+ years) and increased knowledge were associated with practice towards dengue in DSCC (β = 0.02, 95%CI: 0.01, 0.03). Efforts to increase knowledge about dengue fever through education by the administrations of both corporations would benefit from targeting these high-risk groups for a more sustainable outcome.

Perceived Noise Pollution and Self-Reported Health Status among Adult Population of Bangladesh

“…Social media has grown in importance as a source of information for the general public in Bangladesh [ 35 ]. However, all of these approaches must consider literacy and of their recipients when they are designed and implemented [ 36 ]. Public health and disaster management authorities may use these platforms to communicate noise pollution information.…”

CRISPR/Cas9-Mediated Gene Drive to Prevent the Replication of Dengue Virus in the Mosquito Vectors to Reduce the Impact of Dengue Epidemic in Bangladesh

“…In Bangladesh, the first dengue outbreak was recorded in 2000 by the dengue virus serotype DENV 3 [3]. As reported earlier, the climatic condition in Bangladesh (regarding temperature, humidity and rainfall) is quite favorable for the transmission of the DENV through the mosquito vector Ae.…”

“…aegypti vector (in sometimes A. albopictus) [1]. In 2019, Bangladesh was affected by a dengue outbreak that broke all the previous records of infection with 101,354 dengue hospitalized cases [3,4]. The economic burden behind the treatment of each hospitalized patient is $10.…”

“…The economic burden behind the treatment of each hospitalized patient is $10. The burden is increasing to facilitate awareness programs, spray insecticides, and to provide prevention drugs every year, and these strategies have proven to be less effective as much of Aedes mosquitoes have become resistant to the existing drugs [3]. According to research, the increase in dengue cases is driven by the unplanned urbanization, migration, and climate change [4].…”

Massive Third-Wave COVID-19 Outbreak in Bangladesh: A Co-Epidemic of Dengue Might Worsen the Situation

“…Dhaka has experienced high numbers of dengue cases between 2012 and 2019. Since 2016, many dengue endemic countries approved the use of the first-licensed dengue vaccine (CYD-TDV); however, reports of more severe disease manifestations in seronegative individuals interrupt the implementation plan of dengue vaccine in Bangladesh [ 26 ], and mosquito control with adulticides and larvicides remains the primary effective prevention strategy [ 17 ]. The simultaneous outbreak of two vulnerable diseases in a tropical or subtropical country would represent a catastrophic event.…”
