1. Introduction
Malaria is caused by the
Plasmodium parasite, which is transmitted by the bite of a female anopheles mosquito vector. Vector occurrence is highly dependent on the region and the environment. In sub-Saharan Africa with Ghana inclusive, the
Anopheles gambiae complex is the most important vector of malaria [
1]. Its breeding sites are usually freshwater pools created in the rainy season and potentially as spill-over from dams, which leads to a surge in malaria disease during the rainy season and around dam areas [
1]. Increase in malaria can result from a rise in outdoor biting, which can vary between locations depending on endemicity, mosquito species, as well as history of malaria control interventions. Moreover, sociocultural and economic factors, which may include customs, lifestyles and the environment, can be considered vital determinants of malaria transmission [
1]. However, because mosquitoes are only able to bite humans at a particular point in time when they both find themselves at the same place, and human activities such as trading at the market during the night may be equally vital drivers of persistent transmission. Most markets in Greater Accra are surrounded by clogged gutters that contain wastewater and pose a risk for the transmission of malaria.
Malaria poses an enormous burden to the world’s population, with most cases occurring in sub-Saharan Africa [
1]. According to the 2017 World Malaria Report, progress in malaria control has stalled after the initial unprecedented global success [
2]. Malaria is endemic in Ghana [
3] and is known as a serious impediment to social and economic development [
1].
In 2018, notable increases in malaria cases were observed in Ghana (8%) and Nigeria (5%) [
4]. In Ghana, within the first quarter of 2017, about 2.3 million suspected malaria cases were recorded at the out-patient department of one municipal hospital, representing an increase of 1.2% over the same period in 2016 [
5]. One major problem facing the prevention and control of malaria in Ghana is delay in health-seeking due to wrong perceptions of the disease [
5]. The socio-economic aspects of a population are known to contribute significantly to the epidemiology and control of parasitic diseases [
6], such as
Plasmodium infection. For example, a study to determine sociocultural factors influencing malaria control in North Central Nigeria [
7] observed that many of the respondents did not view malaria as a serious problem. The authors further revealed that marriage, educational level, and some occupations appeared to have a positive influence on malaria knowledge [
7]. Moreover, low educational levels and poverty have been asserted to influence malaria spread and treatment-seeking behavior [
8,
9]. A study conducted in India by Sabin et al. [
10] revealed that even though the study respondents perceived malaria as a condition of high clinical significance, they still endorsed traditional beliefs and practices, such as the use of unapproved preventive and treatment strategies [
10]. These reports underpin the importance of assessing the knowledge, attitudes, and practices (KAP) of individuals regarding malaria so as to provide insights into perceptions and behaviors that could aid in tailoring appropriate health education programs and interventions.
Various studies have been carried out to examine the KAP of malaria among different groups of people. For example, in Ghana, studies on KAP of malaria among the populace focused on different study groups, highlighting different aspects of malaria KAP, such as those of rural and urban communities [
11,
12,
13,
14]. Others include KAP of insecticide-treated net use in malaria prevention [
15,
16] and choice of malaria treatment regimens [
17,
18]. Some researchers also concentrated their studies on KAP of malaria among healthcare workers [
15,
17,
19,
20,
21,
22] and vulnerable groups such as HIV patients [
23]. Elsewhere, there have been reports on malaria KAP among pregnant women in Ethiopia [
24], tertiary students in Nigeria [
25,
26], primary school children in Tanzania [
27], and people visiting some referral hospitals in Eritrea [
28]. Other community-based KAP studies have been conducted in various locations, such as northern Nigeria [
29]; southwestern Saudi Arabia [
30]; southwest Ethiopia [
31]; municipalities of Tierralta, Buenaventura, and Tumaco in Colombia [
32]; and four Lubombo Spatial Development Initiative (LSDI) sentinel sites in Swaziland [
33].
One important section of the population that seems to have been overlooked by malaria KAP studies conducted in Ghana is market traders. In Nigeria, one study that touched on malaria KAP of traders [
18] contrasted them with artisans, reporting low knowledge on malaria, with the latter group having relatively poorer knowledge. Interestingly, in another study in that same country [
8], some traders opined that the sun was the cause of malaria. Of concern, especially in Africa, day market traders sometimes sell their products in the sun, making them easily exhausted, while their night counterparts are frequently exposed to mosquito bites, and possibly leading to malaria. Malaria control can only be successful and sustainable if the community regards the disease as very important, has accurate knowledge about it and the willingness to partake in its prevention and control [
34]. Consequently, this study sought to determine the knowledge, attitudes, and practices on malaria in selected markets in Accra, Ghana, by exploring the perspectives of day and night traders of selected markets. To the best of our knowledge, this is the first report on malaria KAP with a focus on day and night market traders. This study provides important insights on the perspectives of day and night market traders on malaria, showing whether knowledge influences their choice of time to trade, and whether their time of trading makes a difference in their malaria related knowledge, attitudes, and practices.
4. Discussion
Malaria is of immense public health importance, particularly, in malaria-endemic regions, such as sub-Saharan Africa, where it causes significant morbidity and mortality amongst vulnerable groups [
4]. The success of efforts aimed at reducing the burden of the disease could be sustained and improved if inhabitants of these regions are well-informed about the disease, including its route of transmission, signs and symptoms, management, and preventive measures [
34]. In line with this, this study sought to unravel the perspectives of an important, but largely overlooked, section of the Ghanaian population—day and night market traders—with regards to their malaria-related knowledge, attitudes, and practices. This is the first malaria KAP report focused on the perspectives of day and night market traders in the country, and respondents were recruited from selected markets within the Greater Accra Region.
The study’s recording of more respondents among day traders compared to night traders, in a ratio of about 2:1, is an observation that depicts the typical nature of Ghanaian markets, which are mostly active in the day, with a large amount of people going there for business. Hence, it is not surprising that a greater proportion of the respondents were day traders. Moreover, most of the study respondents were from the Madina market, whereas a few were from the Dodowa market, and this reflects the geographical distribution of the towns hosting these two markets—unlike Madina, which is closer to central Accra, Dodowa is at the periphery of the region, and seems to have fewer inhabitants.
With reference to knowledge in this study, the observation that almost all (99.7%) of the respondents had heard about malaria is very encouraging, and is consistent with the finding of Singh et al. [
29], in whose study the majority (93.5%) of the respondents had heard of malaria. Similar findings have been reported by Amusan et al. [
36] and Munisi et al. [
37], who respectively indicated that 93.9% and 97.7% of the respondents they interviewed had heard of malaria. The homogeneity of this observation among the current study and those of Singh et al. [
29], Amusan et al. [
36], and Munisi et al. [
37] is consistent with the endemicity of the disease in sub-Saharan Africa.
Still on the topic of knowledge, when respondents were asked about the transmission vector, a high knowledge (95.8%) on the vector was observed, indicating their appreciation of the connection between the disease and bite of mosquitoes. This high level of knowledge on the vector is similar to the 96.9% reported by Amusan et al. [
36] and 95.31% by Munisi et al. [
37]. On the contrary, a study by Okwa et al. [
18], which assessed the KAP of malaria among 50 artisans and 50 traders in selected areas in Lagos, Nigeria, observed that only 4% (
n = 2) of the artisans and 52% (
n = 26) of the traders studied made a connection between malaria and mosquitoes. This disparity in knowledge on transmission vectors was attributed to a reflection of the low educational level of Okwa et al.’s [
18] study population. Knowing the vector responsible for malaria transmission is critical in the control of the disease, and hence is a welcomed observation of the current study.
An interesting perspective was unraveled when respondents were asked if sitting in the sun for long hours caused malaria. Similar proportions of the day (21.5%) and night (21.7%) market traders answered in the affirmative, indicating that misconceptions about the sun and malaria might exist among the market traders. They reasoned that since fever (high body temperature) is associated with malaria, sitting on the sun for a long time would automatically lead to malaria. However, this misconception was held by similar proportions of day and night market traders (21.5% of the day traders and 21.7% of the night traders), suggesting that it had little or no influence on the traders’ choice of time to be at the markets.
Another intriguing perception uncovered during the interactions with the participants was that the word “fever” seems to be synonymously used to mean “malaria”. It is therefore “normal” for someone who wants to say “I have got malaria” to say “I have got fever”. Moreover, being in malaria-endemic communities, where most individuals would have had prior exposure to malaria by the time they reach trading age, it appears as though the respondents do not regard the disease as an extremely dangerous condition. Therefore, it is not surprising for an individual who says “I just had a little fever” to actually mean “I simply had malaria, and nothing more serious than that”.
Therefore, education needs to be directed at these misconceptions to improve overall knowledge about malaria. In contrast, in Godwin et al.’s [
7] study, which was conducted in a malaria-endemic city of North Central Nigeria, only a few of the respondents (less than 0.1%) had such a misconception. In their report, the authors attributed the high knowledge among the study respondents to marriage, educational level, and some occupations of the respondents (being teachers and health workers). In another study conducted in Nigeria among market women, the proportion of respondents who had the noted “malaria–sun” misconception was 12.2% [
8].
Knowledge about signs and symptoms of malaria among the respondents in the current study was nonetheless very good, with 96.4% of the night market traders and 97.8% of day traders knowing about malaria symptoms, which is consistent with the findings of Singh et al. [
29] in Nigeria, Mbohou et al. [
17] in Cameroon, and Owusu et al. [
23] in Ghana. Having sound knowledge about signs and symptoms of the disease is helpful to its diagnosis, treatment, and management.
After computing the overall knowledge score in this study, more than half of the traders had moderate knowledge on malaria, with 54.9% and 40.7% of the respondents respectively having moderate and high levels of knowledge on malaria. This is consistent with findings reported by Ismail et al. [
38] among the majority of primary healthcare workers in Plateau State, Nigeria. Adegun et al. [
39] also reported an overall moderate to a high level of knowledge on malaria, malaria-related issues, and malaria preventive practices among migrant farmers. However, a high overall knowledge was reported among primary school children in Bagamoya, Tanzania [
27]; among employees from enterprises in Douala, Cameroon [
17]; among malaria symptomatic patients in a referral hospital in Tanzania [
37]; and prescribers in Ghana [
22]. This suggests that there is still room for improvement on the knowledge of day and night market traders in the Greater Accra Region and other groups of people sampled in the cited studies. On the contrary, a low overall knowledge was reported by Okwa et al. [
18] among artisans and traders and Owusu et al. [
23] among people living with HIV in rural communities in Ghana. These findings were attributed to the level of education of the artisans and traders and the rural living area of the respondents, respectively. Moreover, the difference between the knowledge level observed in the current study and that of Owusu et al. [
23], which was also conducted in Ghana, may be because the respondents in Owusu et al.’s [
23] study were inhabiting a rural area, unlike the current study whose respondents were sampled predominantly from urban areas.
Identifying mass media platforms and health workers as the means by which the majority of the respondents acquired their overall knowledge is not surprising, because in the capital city there is easy access to information; in fact, almost all the traders had heard about malaria. These traders usually commute to and from the markets via public transport systems, from whence they are often exposed to radio- and television-hosted talkshows, some of which are centered on malaria. The 2019 Ghana Malaria Indicator Survey reported that the majority (82%) of the respondents revealed that they had been presented with messages on malaria on television or radio. Besides the aforementioned avenues for accessing malaria-related information, loud public address systems, which are common features of marketplaces in the country, form part of the mass media platforms through which more than half of the market traders of the current study (54.4%) obtained their malaria-related information. A similar explanation regarding mass media platforms was proffered by Sumari et al. [
27], who attributed the high level of malaria knowledge among the school children in their study to national and local public awareness programs through mass media platforms like radio and television.
Similar to findings reported by Sumari et al. [
27], this study showed that the sources of information on malaria were associated with the level of knowledge on malaria, with mass media platforms and health workers being the most common sources of information reported by the respondents. This study’s finding indicates that respondents’ source of information might determine whether they would have low, moderate, or high knowledge of malaria. Meanwhile, there was no observed difference between day and night market traders’ sources of information, possibly explaining why there was no difference in the knowledge level between the two groups. However, this is a good observation, since it might imply that no matter the time of trading at the market or being at home, there is the chance of receiving some information on malaria.
When the associations between the demographic characteristics of the day and night market traders and their knowledge level were explored, age group and specific markets the respondents traded at were found to be significantly associated with their knowledge level. Regarding the age groups, most of the respondents aged 26 years and above had a high knowledge, with a large proportion of these being in the 36–40 years age group. This is in contrast to a study by Jimam and Ismail [
40], who determined the predictive factors of KAP on uncomplicated malaria. Although those researchers showed that age was significantly associated with the level of knowledge, as was seen in this study, they revealed a likely decrease in KAP with increased age of the patients. This disparity could be as a result differences in study population and setting. The high knowledge level on malaria among those trading at the Dodowa, Makola, Tema Community 1, and Madina markets in comparison with the roadside market, which had the least proportion of traders with high knowledge could be as a result of the location of the market. Dodowa, Makola, Tema Community 1, and Madina are relatively more cosmopolitan than the roadside market. Moreover, as indicated earlier, at the market, there is usually loud radio being played, which may carry information on malaria awareness, and those there may have access to such information unlike those at the roadside.
With regards to respondents’ attitudes toward malaria in this study, 9 out of every 10 respondents reported having ever experienced malaria, further buttressing the view that malaria is endemic in this region [
4] and that education and interventions need to be strengthened to curb this disease. A significant proportion (67.46%) indicated going to the drug store/chemical shop (46.79%,
n = 335) and practicing self-treatment at home (15.92%,
n = 114) when they experience malaria-like symptoms, similar to what was observed by Adedotun et al. [
41]. They reported that in their study that about 90% of suspected malaria cases in children and adults were first treated at home with herbal medications or drugs purchased from drug stores/chemical shops [
41]. Similarly, Okwa et al. [
18] and Munisi et al. [
37] recorded that most respondents in their study indicated self-medication and buying drugs from drug stores, respectively, when asked their initial action they took in response to malaria-like symptoms. On the contrary, studies by Mbohou et al. [
17] and Sumari et al. [
27] reported that the majority of their respondents indicated going to the hospital as their first response. However, in this study, only (233, 32.54%) indicated going to the hospital as their first response. According to the WHO [
42], early diagnosis and prompt treatment of malaria are crucial to prevent severe disease and death hence the first response to malaria symptoms is important. In this study, the initial response of going to a drug store, self-medication, and doing nothing about the malaria-like symptoms was indicated by a large proportion (67.46%) of the study respondents, revealing a clear deficiency in attitude. Therefore, the market traders in the region need to be educated on appropriate measures to take when experiencing malaria-like symptoms, as recommended by the WHO [
37].
When the traders were asked about the important factors that prompted their seeking malaria care at the hospital, the gravity of symptoms was the most cited factor (79.8%), and this is similar to what Singh et al. [
29] reported. In this study, none of the respondents’ attitudes showed a significant association with the two types of traders. This similarity in attitude could be as a result of both groups having no difference in their knowledge level as observed in this study. Furthermore, associating the level of knowledge on malaria to the attitude of traders revealed that the use of laboratory tests to confirm malaria status (
p = 0.003) was significantly associated with the level of knowledge on malaria, an observation of great importance. However, it was observed that 43.94% of traders with high knowledge of malaria did not always take a laboratory test to confirm malaria. Thus, it can be inferred that having a high knowledge of malaria does not translate into a positive attitude. This finding is of great concern, and therefore behavior change communication strategies may need to be used to ensure taking a laboratory test to confirm malaria before commencing treatment. It is recommended by WHO that all individuals with signs and symptoms suggestive of malaria should have a confirmatory laboratory test, either via microscopy or rapid diagnostic test [
37].
With regard to the respondents’ practices on malaria, most of them reported using at least one malaria preventive method, with the majority indicating what seems to be the most common in the Greater Accra Region as their preferred malaria preventive methods—insecticide spray/coil (408, 54.55%) and use of bed nets (232, 31.02%). These two preventive methods were similarly reported by Mbohou et al. [
17], Singh et al. [
29], and Munisi et al. [
37] as the major methods used among their study respondents. Insecticide spray/coil are, however, the most used preventive method in this study, and similar findings were reported by Okwa et al. [
18] who explained that this preference in their study population was due to the higher availability and affordability of mosquito coils and insecticide sprays. In this study, the reasons why traders chose their respective preferred malaria preventive methods were significantly associated with their knowledge level and the main reasons indicated were the measure being more effective and easier to access.
The use of treated bed nets was significantly associated with the knowledge level of traders. However, out of 450 traders (60.65%) who do not use treated bed nets, 167 (37.11%) had an overall high knowledge level, proving to be a worrying observation. The most common reason given for not using treated bed nets was that it was associated with discomfort, and this was consistent with findings reported by Owusu et al. [
23], who revealed that fewer people used insecticide-treated nets among their study population with the reason being that it was “too hot” to sleep under. Meanwhile, in the current study, all traders indicated using at least one malaria preventive method. However, education on the importance of consistent use of at least one malaria preventive method is crucial to reduce the transmission of malaria. In this study, none of the reported practices showed a significant association between the two groups of traders, an observation that could be as a result of both groups having no difference in their knowledge and attitude towards malaria.
Furthermore, with associations between the level of knowledge on malaria and practices of traders, it was revealed that the traders’ choice of drug for malaria treatment (
p = 0.001) and preferred malaria treatment type (orthodox or herbal) (
p = 0.005) were significantly associated with their knowledge level. The majority of the respondents (575, 75.65%) indicated ACTs as their preferred choice of malaria treatment drug, with 45.22% of this group having a high overall knowledge level and 50.61% having a moderate overall knowledge level on malaria, suggestive of a positive translation of knowledge to practice. Moreover, when asked of preferred treatment type, the majority (83%) of the respondents indicated orthodox, while 17% indicated herbal medication, an observation consistent with Mbohou et al. [
17], who revealed that only a small fraction (8.6%) of respondents in their study were resorting to traditional medicine (herbs and parts of plants), and this was attributed to socio-cultural beliefs and practices. On the contrary, Okwa et al. [
18] revealed that the majority of traders in their study used local herbs. The disparity in findings between this study and the findings of Okwa et al. [
18] could be because their study reported an overall low knowledge level among their study respondents, while this study revealed an overall moderate and high level of knowledge among the day and night market workers.
