In China, malaria has been posing a significant economic burden on households. To evaluate malaria economic burden in terms of both direct and indirect costs has its meaning in improving the effectiveness of malaria elimination program in China.
A number of study sites (eight counties in five provinces) were selected from the malaria endemic area in China, representing the different levels of malaria incidence, risk classification, economic development. A number of households with malaria cases (n = 923) were surveyed during the May to December in 2012 to collect information on malaria economic burden. Descriptive statistics were used to characterize the basic profiles of selected malaria cases in terms of their gender, age group, occupation and malaria type. The malaria economic costs were evaluated by direct and indirect costs. Comparisons were carried out by using the chi-square test (or Z-test) and the Mann-Whitney U test among malaria cases with reference to local/imported malaria patients, hospitalized/out patients, and treatment hospitals.
The average cost of malaria per case was 1 691.23 CNY (direct cost was 735.41 CNY and indirect cost was 955.82 CNY), which accounted for 11.1 % of a household’s total income. The average costs per case for local and imported malaria were 1 087.58 CNY and 4271.93 CNY, respectively. The average cost of a malaria patient being diagnosed and treated in a hospital at the county level or above (3 975.43 CNY) was 4.23 times higher than that of malaria patient being diagnosed and treated at a village or township hospital (938.80 CNY).
This study found that malaria has been posing a significant economic burden on households in terms of direct and indirect costs. There is a need to improve the effectiveness of interventions in order to reduce the impact costs of malaria, especially of imported infections, in order to eliminate the disease in China.

Malaria has long been known as a disease of poverty as it is mainly distributed in the poorest regions of the world, e.g., in African countries [1, 2]. Existing studies have demonstrated the striking correlations that exist between malaria and poverty in terms of the in terms of a country’s GDP per capita; the studies have shown that malaria-endemic countries are characterized by a relatively lower level of economic development. In this regard, malaria is beyond a major health problem: it also has significance on the socioeconomic development of poor countries [3, 4]. Furthermore, the relationship between malaria and poverty demonstrates the positive correlations: malaria infections may result in poverty on both the individual and national level and, in turn, poverty leads to worsened health conditions that may aggravate malaria transmission [4, 5]. Malaria accounts for a loss of 35 million disability-adjusted life years annually [6, 7]. Besides the economic loss caused by malaria, the disease can also cause indirect loss in the national level economic development, such as the reductions on the foreign direct investment, tourism, labor productivity, and international trade. At the individual level, malaria may cause poverty due to expenditures on healthcare and treatments, income losses, and early deaths. People living in poverty are considered to be a high-risk population, as they are less likely to be able to access preventive measures or seek prompt effective treatment [4, 8–10].
Given the remarkable success that China has already achieved, and the confidence that it can achieve even more, a strong political commitment was made by the National Population and Family Planning Commission of the Peoples’ Republic of China by the issuing of the National Action Plan for Malaria Elimination (2010–2020). The goal is to eliminate locally acquired malaria by the end of 2015, except for in the border areas of Yunnan Province, and to eliminate malaria nationwide by 2020 . With the continuous reduction of locally acquired malaria, the landscape of malaria endemics have changed significantly, which generates a new set of challenges . One of these is the changing proportions of local and imported cases .
The proportion of imported malaria cases has increased significantly due to the growing overseas investment, and the numbers of Chinese laborers working abroad and then returning home. In this analysis, an imported case of malaria was defined as case of malaria acquired in a known malarious area outside of China. In China, the following criteria for imported malaria must be simultaneously met: 1) the patient was given a diagnosis of malaria; 2) the patient has a history of travel to malaria-endemic areas outside of China during the malaria transmission season; and 3) the onset time for malaria was <1 month after returning to China during the local transmission season.
The total number of Chinese laborers and travelers abroad in 2012 was estimated to be 0.5 million and 83.2 million, respectively, which increased by 24.6 and 44.9 %, respectively, when comparing with figures from 2010 [14, 15]. According to a web-based surveillance and reporting system, although only a total of 2 570 malaria cases were reported in 2012, a reduction of 67.28 % compared with the 7 855 cases reported in 2010, the proportion of imported cases increased sharply from 54.26 % (4 262/7 855) in 2010 to 94.71 % (2 434/2 570) in 2012.
Although malaria still poses a health and economic burden for the poor population in China and imported malaria remains a potential threat , only a limited number of studies have been conducted on malaria management costs at the household level. There are only two related available reports focusing on cost-effectiveness of malaria programs in China [17, 18]. The economic cost of endemic malaria has received little attention and has not been adequately documented until now. Information on the economic consequences of getting infected with malaria at the household level is an important complementary tool needed to successfully formulate policies in areas such as health financing, introduce innovative strategies, and regulate health facilities [19–21].
This is the first study based on a systematic survey conducted in the main malaria endemic areas that endeavors to give an in-depth analysis of malaria management costs at the household level throughout the country. Having this information could help prioritize current interventions for malaria elimination.
Sampling and data collection
We collected information on reported malaria cases in each selected county, based on surveillance data from the Chinese Information System for Disease Control and Prevention. All cases were laboratory confirmed by microscopy and positive cases were treated according to national policy. A questionnaire was developed based on a workshop presented by stakeholders in order to collect the following data: background information, healthcare-seeking behavior, working days lost, and expenditure on malaria diagnosis and treatment.
From May to December 2012, all selected malaria cases (n = 923) were interviewed using the standard questionnaire. A principal supervisor and two investigators monitored the data collection process. A household was defined as a person with his spouse, unmarried children, and related or unrelated persons, who live together and constitute one unit. The household head or a representative (i.e., in the situation that household head was not accessible during the interview period) was interviewed to obtain information on treatment-seeking behavior and the amount of money spent to treat malaria. For children subjects, either their mother or both parents were interviewed.
Economic costs were calculated in Chinese Yuan Renminbi (CNY). Descriptive statistics were used to characterize the basic profiles of selected malaria cases in terms of their gender, age group, occupation and malaria type. The malaria economic costs were evaluated by direct and indirect costs. Comparisons were carried out by using the chi-square test (or Z-test) and the Mann-Whitney U test among malaria cases with reference to local/imported malaria patients, hospitalized/out patients, and treatment hospitals. A P-value less than 0.05 was considered statistically significant.
Economists classify costs according to their traceability (direct and indirect) to the object or activity , or by their relationship to the output (fixed and variable). Direct and indirect costs are used by health economists to classify (demand-side) patient costs associated with illness . In our study, direct costs for all malaria patients included payment for examinations, drugs, and treatment. Indirect costs included the patients’ and caregivers’ lost labor productivity or loss of incomes, as well as costs incurred by caregivers, such as for transportation and food. Productive work was broadly defined as involvement in any economic activity with the potential to add to the disposable income of the household. The total numbers of working days lost by both the patients and their caregivers were recorded. Indirect costs were calculated both at the household level and for cured malaria cases.
We obtained ethics approval from the ethical committee of the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention (WHO Collaborating Center for Malaria, Schistosomiasis and Filariasis). Written informed consent was obtained from all participants. No specific local permissions were required, and the field studies did not involve endangered or protected species.

Malaria has been posing a significant economic burden on households in the study areas
This study was the first to analyze direct and indirect costs associated with malaria management during the malaria elimination stage in China. The study found that the average costs for local and imported malaria cases were 1 087.58CNY and 4 271.93CNY, respectively. Although the basic antimalarial drugs have being offered for free in the National Malaria Elimination Programme, many households with malaria patients in the study areas spent their money on more public health services, such as blood examination, and private sources of treatment. The surveyed households spent about 13.9 times more on malaria treatment than the average per capita daily income per year, which accounted for about 11.1 % of a household’s total income. According to studies, the economic losses incurred due to the disease are equivalent to as much as 0.6–1.3 % of the GDP in countries with high malaria incidence rates . With the increasing overseas investment and growing number of Chinese people working abroad, the number of imported malaria cases has also increased sharply, and the costs of imported cases are an unavoidable challenge for the elimination of malaria in China. However, the findings of this study were consistent with those of other studies about household costs of malaria management. This study found that the direct costs were lower than the indirect costs, showing that most of the costs went on drugs and were incurred due to loss of working days in the study areas. Other studies have found that indirect costs constitute more than 75 % of the total costs [23–25]. In Ghana and Sri Lanka, the indirect costs for malaria management accounted for 79 %  and 76 %  of the total costs, respectively. This study as well as others has shown that the highest proportion of malaria treatment expenditure goes on drugs [3, 4].
The most striking finding of this study was the pronounced increase in the costs incurred by malaria patients who were treated in a hospital at the county level or above
In terms of the average cost, it was about 4.23 times higher than for those treated at a village or township hospital (i.e., 3 975.43/ 938.80). In terms of the direct cost, it was near 10 times higher for getting treated at a hospital at the county level or above than getting treated at a village or township hospital (i.e., 2 275.95/240.66). Furthermore, 24.0 % of patients who were diagnosed at a village hospital opted to get treated at a county or above hospital, which significantly increases patients’ costs. Therefore, the results confirmed that early diagnosis and quick treatment in the local village or township hospitals would reduce the related costs significantly. Besides the direct and/or indirect medical treatment costs, malaria can impose other types of economic costs. For one thing, malaria infection will change household’s behaviors, such as patients might be inclined to be absence of indoor work which might possibly expose them to mosquitos’ biting. And people will also tend to stay in their own counties instead of going to work abroad, especially in the border areas. For another, malaria infection can lead to economic costs in the macro level, which cannot be assessed in this study at the household level. For example, with the nature of pandemic, malaria outbreaks can affect the willingness of international trade, tourism, and foreign investment, etc..
Another limitation of this study was the fact that mental stress and social costs of families with sick members were not included, which are in general very difficult to evaluate in a short period of time. Furthermore, the differences in epidemiology of malaria between regions and the absence of a generally accepted methodology to measure the economic impact of the disease made it difficult to compare the findings of this study directly with other studies.
Conducting qualitative research to obtain in-depth, locally relevant, and descriptive data on malaria costs should be encouraged. During the data analysis, we had limitations on capturing the correlations between the malaria costs with participants’ demographical, social, and economic status, e.g., gender, age, occupation, etc. Good-quality case management is crucial to efficiently use resources expended on the malaria elimination program: if case management is not done well, less is achieved and scarce health resources are wasted, which is likely to increase the risk of malaria transmission in the future.
Malaria poses a significant economic burden on rural households and individuals in terms of direct and indirect costs. There is a need to develop effective strategies and interventions aimed at reducing malaria management costs at the household level in order to achieve the elimination goal in China. This study explored a systematic survey conducted in the main malaria endemic areas that endeavors to give an in-depth analysis of malaria management costs at the household level throughout the country. For effective management of imported malaria cases, surveillance and response systems should be carefully planned and well managed to ensure early diagnosis and prompt treatment. In addition, health education should be provided to all mobile laborers and other travelers before they travel abroad and after they return home. Health education materials should be provided to entry and exit border stations, and to local Centers for Disease Control and Prevention so that timely malaria tracking can be implemented. Training should also be provided to physicians to ensure the provision of accurate diagnosis and appropriate treatment.
