Abstract

Prevention is the most efficient way to get rid of any pandemic; it is no exception to Dengue

Fever (DF). Assessment of public knowledge and health credentials is critical for designing

strategies for any disease prevention. This study aims to explore awareness, health

perceptions and preventative measures of Dengue Fever (DF) in various social and economic

segments in Dhaka, Bangladesh. A cross-sectional questionnaire survey of 242 respondents

attending the dengue awareness events was conducted. The information on socio-

demographic characteristics of the participants and their knowledge, attitude and practice on

dengue fever was collected. The findings of this study revealed that there is no doubt among

the 76.4% (n=185) participants that Ades Mosquito is mainly responsible for Dengue. The

majority 97.5% (n=236) of the respondent believe that dengue is becoming a serious health

problem in this region. The causes of dengue in this region are water mismanagement

(39.7%), water clogged (33.9%), poor drainage system (18.2 %). This study found different

responses associated with the characteristic of insect and 99.2% of the respondents have not

enough knowledge about dengue and Aedes mosquito. Also, the respondents have not shown

enough attitude and awareness (96.3%) to dengue, and most of the respondents have

moderate level (72.3%) prevention practices on dengue fever (DF). Finally, this study

concluded that the Health Belief Model does not work in Bangladesh.

Introduction

Dengue is a mosquito-borne1 disease which is caused by Aedes aegypti's2 bite (Kumar and R.

Kumar, 2013). While dengue is an ancient disease, Chinese medical records incorporated the

first indication of the disease. Accordingly, the disease was first identified in 992 AD in

China. However, some researchers claim the illness mentioned in China's Xin monarchy

documents (265-420 BC) was described as a poisonous water disease' caused by flying

insects (Bostan et al., 2016). Among the places where dengue mosquitoes and viruses are

found in South Asia, the Caribbean, the Indian subcontinent, South and Central America,

Africa, the Pacific Islands and Australia. In the Philippines and Thailand, around 1950s

dengue was first diagnosed as an outbreak. The outbreak of Dengue Fever (DF) had only

been seen in nine countries before 1970. But now, in more than 100 countries3, dengue fever

(DF) is being seen. The disease has widespread in the last 25 years of the 20th century

(Prasittisuk et al., 1998; Kuno, 2009).

In South America and Asia Dengue is more prevalent than anywhere else in the world. In

2019 alone, 1.6 million people were infected with the mosquito-transmitted disease in South

America. The prevalence of dengue is extreme in most countries in Southeast Asia, countries

such as the Philippines, Sri Lanka, Malaysia, Cambodia, Laos, Vietnam and Thailand are

work victim of dengue epidemic. As the amount of Aedes mosquito permeates, the number of

patients suffering from dengue is growing. Nearly 40% of the world's total population is at

risk for dengue (Villar et al., 2015). The disease has grown as much as 30 times in the last 50

years. As a result of this rapid expansion, this disease affects about 100 million people in the

world's tropical areas. Because of this disease, 20000 people die in a year alone and about 25

people per minute (WHO, 2012a).

Other than those urbanizations and polluted climates, the climate change such as temperature

rise, constant rainfall and travel from one continent to another continent is increasing the

prevalence of dengue fever (DF) (Karim, Munshi, Anwar, and Alam, 2012). Rachel Lowe, an

assistant professor at the London School of Medicine and Hygiene, says the warmer climate

has created a favorable environment for dengue outbreaks through virus reproduction and

mosquito breeding (Prothom-Alo, August 9, 2019). Thus, the dengue fever (DF) and dengue

mosquito have taken a dire shape for everyone. About six billion people will be at risk of

getting dengue fever (DF) by 2080 (Messina et al., 2019).

are reported (Messina et al., 2019).

Bangladesh as a subtropical country has nearly all the specific weather conditions that enable

the Aedes aegypti and Aedes albopictus to thrive. Dengue is affecting more and more people

in the country because of this urbanization, climate change and demographic factors

(Chowdhury, 2019; Lam, 1993). This epidemic of the disease has been in the country for the

last two decades (IEDCR, 2019). In previous years, Dengue area included only several of the

country's divisional cities but recently patients with dengue were found in remote areas of the

country4 as well. The number of people affected doubled in 2019 relative to the statistic from

2018 and in the same year 107 deaths attributed to dengue (The Daily Star, 2019; IEDCR,

2019).

The prevalence of dengue fever (DF) in Bangladesh is generally high due to the monsoon

season from July through October (WHO, 2019). During this time the drain, floral tub, barrel

and plastic containers filled with stagnant water, which is conducive for mosquitoes to lay the

eggs on it. The Disease Control Division of the Department of Health, the Ministry of Local

Government, the City Corporation and the Pesticides Department of the Municipality of

Bangladesh work in mosquito control during this time (Islam, 2019). Yet failure to kill

mosquitoes and lack of effective anti-mosquito medicines in cities shows that Bangladesh is

far behind in dengue disease control (Morol, 2019). In such a situation this study aims to

examine the triggers and solutions of Bangladesh's dengue epidemic.

Literature review

The studies that have been done on Dengue have highlighted the causes of Dengue

prevalence, the effects of Dengue and the ways to prevent dengue. In Australia's case, Russell

et al., (2009) studied the possible impact of climate change on dengue spread in Australia.

According to them, dengue outbreaks are currently limited to Queensland, Australia, but with

rising temperatures, Aedes mosquitoes are likely to rise significantly in some Australian

regions. Important factors for the future spread of dengue and vectors are increased

reproduction of dengue mosquitoes in Asian and Pacific countries, and transmission of

viruses from Asian and Pacific countries.

In his study, Gubler (2011) contended that half of the world's population lives in areas at risk

of dengue. During the past 40 years, the dengue epidemic has increased dramatically. Several

factors are responsible for this increased outbreak but the significant ones are urbanization,

globalization and lack of mosquito control. The cities have modern airports through which

millions of travellers fly each year, but the mosquito control system is not successful. As a

result, the virus spreads from one area to another and the dengue takes on the appearance of

an epidemic.

Wu et al., (2009) explain dengue incidence in Taiwan as a result of high temperatures and

urbanization. Their work investigates how dengue mosquitoes can be affected by temperature

and other environmental factors. They presented dengue mosquito spatial patterns in 356

cities using the Geographic Information System (GIS) and found that the dengue risk

increases when urbanization is high and the average monthly temperature is greater than 18

4 According to data from DGHS (2019), 87,953 people were infected with Dengue in the

country from 1 January to 30 September 2019, of whom 57,166 were in the Dhaka Division,

6740 in the Chittagong Division, 9009 in the Khulna Division, 5704 in the Barisal Division,

4724 in the Rajshahi Division, 953 in the Sylhet Division and 2143 in the Mymensingh

Division.

degrees Celsius. The monthly average 1-degree Celsius rise in temperature increases the risk

of dengue infection by 1.95 times.

Harving and Rönsholt (2007) reflect on the family-level economic impact of dengue

hemorrhagic fever. For their study, they included 155 children aged 0-15 in South Vietnam.

Parents or guardians of children who were hospitalized for 10 weeks were interviewed to

determine the cost of care for their child. The study found that the average (direct and

indirect) family expenditure on treating a child in South Vietnam is around $61.

Hospitalization costs are reduced parental income which creates an economic burden on a

family. Clark, Mammen, Nisalak, Puthimethee, and Endy (2005) emphasized the economic

impact of dengue hemorrhagic fever on Thailand's family level. This study shows that the

direct hospitalization expense per hospitalized patient unit, the indirect cost due to

productivity loss, is about $61, which is higher than the average monthly income in Thailand.

All studies show the economic effect of dengue hemorrhagic fever on the family level. These

two studies only discussed the economic impact of dengue, but there is a lack of discussion

on the social impact that dengue has.

Recent reports from Ooi, Goh, and Gubler, (2006) indicate that dengue infections in

Singapore have risen over the last decade. The explanation for such an epidemic is the lack of

safe and effective dengue virus tetravalent vaccine and the lack of sustainable prevention.

Researchers stressed the need to increase the cost of successful vector control programs,

reduce Aedes aegypti species and restrict the importation of dengue virus into Singapore to

avoid dengue. Researchers even said, in Singapore, prevention of dengue infection is not

feasible without eliminating dengue in neighboring countries. Therefore, regional efforts to

control dengue need to be made.

Banu et al., (2012) shows the impact of climate change in Bangladesh with the prevalence of

dengue epidemic. The changing climate such as temperature and humidity affects vectors and

viruses which result in vector-borne diseases becoming severe and spreading. Authors

predicted that the temperature would rise to 3.3 degrees Celsius by the end of this century and

thousands of dengue cases would increase due to no adaptation of the socio-economic

conditions.

Raheel et al., (2010) researched dengue in the Indian subcontinent. Their research aims at

examining the reported cases of dengue hemorrhagic fever and defining the triggers for the

dengue fever (DF) outbreak. Their study results show that climate change, rainfall,

temperature and humidity are contributing to outbreaks of dengue. Mosquito-borne diseases

like dengue have been growing in the Indian subcontinent for the last few years.

Salje et al., (2019) conducted the study on dengue in Bangladesh, which has been

transformed into a common disease and burden. They selected 5866 individuals who had

been tested for IgG serum and in terms of collecting data. They found that 40% of the people

are infected nationally and 2.4 million people are infected annually. As a result of their

research, dengue can be prevented in Bangladesh by increasing vector surveillance and

understanding how dengue is spreading.

It is evident from the literature review above that researchers have researched the causes of

dengue, the consequences of dengue and ways of avoiding dengue. But there is no research

work conducted in Bangladesh portraying the field causes and remedies of dengue fever (DF)

in Bangladesh. Thus, there remains a research lacuna in this particular field of study. This

study aims to meet that research lacuna.

Methodology

Study duration and location

A cross-sectional study survey was conducted in June 2019 at Dhaka city (DNCC5 and

DSCC6), Bangladesh. The facilities between these two locations are similar to one another

with a community formation and residential buildings.

Sampling procedure and survey

A purposive sampling method was used to select a sample of participants to represent the

general community of DNCC and DSCC. By using a sample size calculator (G power

calculator), it was estimated that a minimum of 242 households should be sampled to gain a

90% confidence level, with a maximum allowable difference of 0.05 in detecting the KAP

proportions in the population. A dengue awareness event was held at both localities

separately and the survey was done reporting a total number of 242.

A structured questionnaire on knowledge, attitude and practice of dengue control was

prepared. It was printed in local language and the questionnaire was divided into three

sections; the first section covered the knowledge on Aedes and dengue consist of 16

questions, the second part concerned with attitude and consists of 08 questions which were

based on Health Belief Model (HBM) and covered concepts known as severity, susceptibility,

perceived barrier and perceived benefit. For scoring, a Likert scale 1 to 5 was given to each

perception varying from strongly agree, agree, neutral, disagree, strongly disagree. The last

part was related to practices with 19 questions in total. The overall reliability of the

questionnaire was acceptable with Cronbach-alpha value of 0.763 (Cronbach, 1951).

Data analysis

The data collected from the questionnaire were entered and analyzed using the Statistical

Package for Social Sciences (SPSS) version 23.0. All of the questions were analyzed and

assessed individually using a scoring system. Each of the appropriate answers was given a

point and was totaled for each section. Respondents were considered to have sufficient

knowledge (16 questions), satisfactory attitude (08 questions) and have good preventive

practices (19 questions) if they correctly answered 75% in each of the section of the

questions.

becoming a serious health problem in this region. Among the total number of the participant

95.9% (n= 232) knows that dengue is dangerous diseases and 88.8% (n=215) believe that

dengue can cause death. When they asked about the cause of dengue in this region or area

39.7% (n=96) said about unmanaged water, 33.9% (n=82) said about water clogged, 18.2 %(

n=14) said about drainage system is not work and similarly, 4.1 %( n=4) given opinion that

they don’t know about that. Anyone can be infected by the dengue said by majority

respondent and their percentage is 92.6% (n=224).

Dengue is an upcoming disaster and serious issue that’s why having sufficient knowledge

about sign and symptoms of dengue infection is very important. To know about the depth of

knowledge about sign and symptoms of dengue among the respondents, we set multiple

response questions to understand the knowledge of the symptomatology of dengue, and the

result is that 8% (n=2) said that they don’t know about the sign and symptoms of dengue, in

contrast, majority of the respondent's response associated with dengue are-continuous fever

77.3% (n=187), headache 59.5% (n=144), skin rash 53.3% (n=129), muscle pain 75.2%

(n=182), small bleeding at gun and nose 22.3% (n=54), diarrheoa 10.3% (n=25), nausea/

vomiting 43.4%(n=105).

When they were asked about what they would do immediately after infected by dengue,

majority of the respondent said that they would immediately seek for treatment and their

percentage is 85.5% (n=207), in contrast equally 5.4 % (n=13) said that they would drink

papaya leaf juice and drink plain water.

Knowledge on Ades Mosquito

There is no doubt among the 73.6% (n= 178) respondent that Ades mosquito is the carrier of

the dengue disease. This study found different or multiple responses to the characteristics of

the insect. Common response associate with the characteristic of insect is- brown and hairy

3.3% (n=8), black and white stripes on the head 24% (n= 58), shelled body with stripes on

the wings 7% (n=17), black and white stripes on the body and legs 44.6% (n=106). In

contrast, 21.9% (n=53) respondent said that they don’t know about the characteristics of the

insect. On the timing of the mosquito biting habits, 30.6% (n=74) of the respondent said

‘dawn and early morning’ while 44.6% (n=108) respondent said ‘early morning and late

evening’ and dusk 16.5% (n=40), and 5.8% (n=14) respondent don’t know about the timing

of the mosquito biting habits.

Majority of the respondent 40.1% (n=97) don’t know about the duration of Ades Mosquito

life cycle from egg to adult. Most of the respondent is informed about the potential breeding

spots inside the house. They mentioned several spots and these are-pot liner 52% (n=126),

toilet flush/tank 53.7% (n=130), refrigerator tray 55.4% (n=134). Respondent also mentioned

several techniques to prevent breeding spots. Majority of the respondent 65. 4% (n=157) said

that they should manage waste and recyclables properly, 64.6% (n=155) said that they should

clean the clogged water every 3 days, 44.2% (n=106) said that they should use mosquito nets

at the time of sleeping.

Attitude towards Dengue

Using Health Believed Model (HBM) we developed some questions to understand the

attitude of the respondent regarding dengue and Ades mosquito prevention (Table 2).

Respondents are confident enough that dengue is a dangerous and serious illness. Majority of

the respondent 62.8% strongly agree that dengue fever (DF) is very dangerous. In contrast,

interesting findings is that similarly 1.7% of the respondent strongly disagree with this

statement. Among the participant of this study 19.8% strongly agree with this statement that

dengue fever (DF) can occur death and 33.9% of the participant simply agree with this

statement. In contrast, 12% of the whole respondent strongly disagree with this statement that

dengue can occur death. 31.8% of the respondent still strongly agrees that they are afraid of

dengue fever (DF) despite having medical facilities and 41.3% respondent are simply agree

with this statement. Most of the people of this region are very worried when they get bitten

by a mosquito. 28.5% of the respondent strongly agree with this statement that they are

worried when they get bitten by a mosquito and 37.6% of the respondent simply agree with

this statement. In opposite 9.9% strongly disagree with this statement. 23.6% of the

respondent strongly believes that anyone can be infected by the dengue fever (DF) and 52.5%

simply agree with this statement. In contrast, 2.5% strongly disagree with this statement.

Continuous fever is a sign of dengue fever (DF) and it is an issue of worry. 31% respondent

strongly agree with this opinion and 56.6% simply agree with this opinion.

Dangerous dengue fever (DF) can be controlled and prevent through raising awareness

among the people. Here 19.4% respondent is strongly and 58.7% of the respondent simply

agree with this statement. And here interesting findings is that still, 5.4% disagree with this

statement. Each person has an important role in preventing dengue fever (DF). Here our study

finds out that 22.2% of the research sample strongly agree with this statement and 44.2%

simply agree with this statement. In contrast, 4.9% of the research sample strongly disagree

with this statement.

Dengue is an upcoming threat to the overpopulated area. And dengue is a threat to the health

wellbeing of this country. Here 27.3% of the respondents strongly agree that it is a major

problem of this country and 46.8% simply agree with them. In opposite, 3.7% of people still

here they do not agree with them.

Environment plays an important role in the transmission of dengue diseases among people.

This study finds out that majority of the respondent simply agree with this statement and their

number is 50% and 14% strongly agree with them. Sometimes dengue causes a death that

means dengue has high morbidity. Here this study finds out that 22.7% strongly agree with

this statement with additional 39.3% of the respondent. Impact of dengue can decrease the

economic productivity. 16.9% of the respondent strongly agrees with this statement and

40.5% respondents are simply agreed with them.

Several positive practices mentioned by the respondent when collecting data on dengue

control issue. Preventive practice can control dengue fever (DF) and can reduce the

vulnerability of the dengue situation. Majority of the respondent 76.9% (n=180) throw waste

in tied plastic trash and tightly closed the trash. In opposite, 23.1% (n=56) don’t have good

practice. The number of respondent 75.2% (n=182) ensure their water containers is tightly

closed each time after use. In contrast, 24.8% (n=60) don’t do that. Majority of the

respondent 71.1% (n=172) clean their water inside the container once a weak and 28.9%

(n=70) of the respondent doesn’t do that. 65.7% (n=159) respondent destroy damaged

equipment that can store water. Regularly 50.8% (n=123) respondent check for mosquito

breeding spot outside the house and 76.4% (n=185) inside the house. In contrast, 49.2%

(n=119) do not check the mosquito breeding spot outside the house and 23.6% (n=57) inside

the house. One of the interesting findings of this study is that majority of the respondent

52.5% (n=127) do not use mosquito net during the time of sleeping and only 47.5% (n=115)

respondent use a mosquito net. Majority of the participant 53.3% (n=129) do not use

mosquito aerosol/spray every day in contrast, 46.7% (n= 113) respondent use it in regular

basis.

Knowledge, Attitude and Practice Score

As depicted in the below table (Table 4) 99.2% of the respondents have not enough

knowledge about dengue and Aedes mosquito. Also, they have not shown enough attitude

(96.3%) in dengue. However, most of the respondents have moderate level (72.3%)

prevention practices on dengue.

The above table (Table 5) shows that there is a positive significant correlation between

knowledge and practices of dengue; also, there is a positive correlation between attitude and

practice; but there is a negative relationship between knowledge and attitude, i.e. there is no

relationship on knowledge and attitude.

The model in the table (Table 6) depicts that there is a negative relationship with the gender-

based knowledge, attitude and practices. So, there is evidence that the Health Belief Model

does not work in Bangladesh. The respondents do not have much knowledge of dengue and

Aedes mosquitos, also they do not have a favorable attitude and practice to prevent the

diseases and to reduce the breading place of Aedes mosquitos.

Conclusion

It can be claimed that the adult population of Dhaka city, Bangladesh do not have adequate

knowledge related to dengue. Yet, the overall prevalence of sufficient knowledge based on

these criteria is moderate. This interpreted into poor attitude yet perplexed as the respondents

have good preventive practices against the disease. Possibly, the critical dengue situation in

their areas compelled them to conduct preventive practices. Among citizens in Dhaka, public

awareness regarding dengue is limited. Awareness, understanding of the hazard and self-

efficacy are significant predictors of effective prevention strategies for dengue. Prevention

and control approaches should be concentrated on increasing consciousness of the hazard

through television. The health campaigns will indeed be constructed to increasing the soul-

efficacy of individual people.

Analysis regarding public knowledge and health attitudes on hemorrhagic fever holds the

most significant part in the implementation of outbreak prevention measures. The findings of

this research illustrate the extent of general knowledge, health commitments and current

prevention measures toward dengue fever (DF). We analyzed awareness of dengue and

prevention measures related to demographic characteristics and public health values. The

findings of the study are taken into consideration to help design health campaigns addressing

the reduction and management of dengue fever (DF). This study also reveals that public

awareness has a significant effect on the implementation of prevention measures on dengue.

Knowledge regarding dengue could be propagated throughout the community to maximize

the knowledge and awareness of the vulnerability to this outbreak. This will also be essential

that health campaigns provide details that can improve patient trust and may also help

alleviate this outbreak in the community by adopting appropriate measures to prevent.
