Background Malaysia is on track towards malaria elimination. However, several cases of malaria still occur in the country. Contributing factors and communal aspects have noteworthy effects on any malaria elimination activities. Thus, assessing the community’s knowledge, attitudes and practices (KAP) towards malaria is essential. This study was performed to evaluate KAP regarding malaria among the indigenous people (i.e. Orang Asli) in Peninsular Malaysia. Methods A household-based cross-sectional study was conducted in five remote villages (clusters) of Orang Asli located in the State of Kelantan, a central region of the country. Community members aged six years and above were interviewed. Demographic, socio-economic and KAP data on malaria were collected using a structured questionnaire and analysed using descriptive statistics. Results Overall, 536 individuals from 208 households were interviewed. Household indoor residual spraying (IRS) coverage and bed net ownership were 100% and 89.2%, respectively. A majority of respondents used mosquito bed nets every night (95.1%), but only 50.2% were aware that bed nets were used to prevent malaria. Nevertheless, almost all of the respondents (97.9%) were aware that malaria is transmitted by mosquitoes. Regarding practice for managing malaria, the most common practice adopted by the respondents was seeking treatment at the health facilities (70.9%), followed by self-purchase of medication from a local shop (12.7%), seeking treatment from a traditional healer (10.5%) and self-healing (5.9%). Concerning potential zoonotic malaria, about half of the respondents (47.2%) reported seeing monkeys from their houses and 20.1% reported entering nearby forests within the last 6 months. Conclusion This study found that most populations living in the villages have an acceptable level of knowledge and awareness about malaria. However, positive attitudes and practices concerning managing malaria require marked improvement.
Background Malaysia has already achieved remarkable accomplishments in reaching zero indigenous human malaria cases in 2018. Prompt malaria diagnosis, surveillance and treatment played a key role in the country’s elimination success. Looking at the dynamics of malaria distribution during the last decades might provide important information regarding the potential challenges of such an elimination strategy. This study was performed to gather all data available in term of prevalence or incidence on Plasmodium infections in Malaysia over the last four decades. Methods A systematic review of the published English literature was conducted to identify malaria distribution from 1980 to June 2019 in Malaysia. Two investigators independently extracted data from PubMed, Scopus, Web of Science and Elsevier databases for original papers. Results The review identified 46 epidemiological studies in Malaysia over the 39-year study period, on which sufficient information was available. The majority of studies were conducted in Malaysia Borneo (31/46; 67.4%), followed by Peninsular Malaysia (13/46; 28.3%) and in both areas (2/46; 4.3%). More than half of all studies (28/46; 60.9%) were assessed by both microscopy and PCR. Furthermore, there was a clear trend of decreases of all human malaria species with increasing Plasmodium knowlesi incidence rate throughout the year of sampling period. The summary estimates of sensitivity were higher for P. knowlesi than other Plasmodium species for both microscopy and PCR. Nevertheless, the specificities of summary estimates were similar for microscopy (40–43%), but varied for PCR (2–34%). Conclusions This study outlined the epidemiological changes in Plasmodium species distribution in Malaysia. Malaria cases shifted from predominantly caused by human malaria parasites to simian malaria parasites, which accounted for the majority of indigenous cases particularly in Malaysia Borneo. Therefore, malaria case notification and prompt malaria diagnosis in regions where health services are limited in Malaysia should be strengthened and reinforced to achieving the final goal of malaria elimination in the country.

While there has been a tremendous decline in malaria disease burden in the remote parts of Malaysia, little is known about malaria incidence in its urban localities. This study aimed to analyze trends of malaria cases in urban Kuala Lumpur, Malaysia. All suspected cases presented to a university hospital in Kuala Lumpur from January 2005 to December 2020 were examined by microscopy. Infection status was analyzed using descriptive statistics and curve estimation analysis. Of 3105 blood films examined, 92 (3%) were microscopically confirmed malaria cases. Plasmodium vivax infections accounted for the majority (36.9%) of all malaria cases. Nearly half (47.8%) of cases were found among foreign cases (p < 0.001). The majority of foreign cases were male (86.4%) and came from Southeast Asian countries (65.9%). The curve estimation analysis showed significant decreases in malaria cases due to P. vivax (R2 = 0.598; p < 0.001) and Plasmodium falciparum (R2 = 0.298, p = 0.029), but increases for Plasmodium knowlesi (R2 = 0.325, p = 0.021) during the 16 years. This study showed that malaria incidence in urban Kuala Lumpur is low and has remained stable since 2005. However, P. knowlesi has played a significant role in the increase in overall malaria in the area, highlighting the importance of continued vigilance and improved surveillance.
Background: Malaria remains a major public health challenge in Thailand. In Thailand, the transmission now progressively clusters in hotspots along international borders and among high-risk groups, including forest-goers. Therefore, continuous assessment and understanding of the behavioral and perceptions related to malaria exposure in the high-risk group are necessary to achieve the elimination goal. This study aimed to investigate knowledge, attitudes and practices (KAP) related to malaria in rural communities living close to a forested area in the northeastern part of Thailand.Methods: A community-based cross-sectional survey was conducted in three forest-goer communities (i.e. Ban Khok, Ban Koh and Dong Yang) in Khamcha-i district, Mukdahan Province from July and August 2019. Community members aged 18 years and above were interviewed. Demographic, socio-economic information and KAP data were collected using a structured questionnaire. Data were analyzed using descriptive statistics.Results: Overall, 346 individuals were interviewed. Although the household indoor residual spraying (IRS) coverage was 100%, ownership of mosquito bed net was 24.3% and only reported in Ban Khok. Nevertheless, almost all of the respondents were aware that malaria is transmitted by mosquitoes (97.7%) and bed nets were used to prevent malaria (94.5%). Regarding practice for managing malaria, the most common practice adopted by the respondents was seeking treatment at the nearby clinic (58.1%), followed by self-healing (38.7%) and self-purchase of medication from a local shop (3.2%). Concerning attitude towards malaria transmission, 69.1% and 24.3% of the respondents reported entering nearby forests and spending the night in the forest within the last six months, respectively. Conclusion: This study found that most respondents living in the villages have an acceptable level of knowledge and awareness about malaria. Nevertheless, the positive attitudes and practices concerning malaria prevention measures against malaria require marked improvement. Therefore, new approaches to improving malaria KAP evidently need in this community.
