The economic cost at the household level of labor days lost due to malaria and other illnesses was estimated in a rural community in Sri Lanka. Over a one-year period, 223 episodes of malaria were recorded from the 298 inhabitants of the village. Based on daily activity records, the economically active age group was defined as 14-60 years. In this age group, 1.8% of working days were lost due to malaria and 5.2% due to all other illnesses. The value of a labor day lost was based on the actual rural wage rate for children, women, and men, with weeks during periods of high labor demand weighting more than weeks during lean agricultural periods. In this way the annual economic loss per household amounted to US $15.56 for malaria and US $47.46 for all other illnesses. This corresponded to a loss of 6% and 18% of annual household net income, respectively. Although the overall economic impact was limited, malaria cases were concentrated in an important agricultural season. During this season, 5.6% of working days were lost due to malaria. In addition, children, who were not part of the economically active population, lost 10% of school days due to malaria during the high transmission season. In estimating the socioeconomic impact of malaria and in measuring cost-benefits of malaria control interventions, these costs have to be considered together with direct expenditures incurred by households such as on treatment and travel and with costs for the service providers.
在斯里兰卡的一个农村社区，对因疟疾和其他疾病导致劳动力天数损失的家庭层面经济成本进行了估算。在一年时间里，从该村庄的298名居民中记录到223例疟疾病例。根据日常活动记录，经济活跃年龄组被定义为14至60岁。在这个年龄组中，1.8%的工作日因疟疾而损失，5.2%因所有其他疾病而损失。损失一个劳动力日的价值是根据儿童、妇女和男子的实际农村工资率确定的，劳动力需求高峰期的周数权重高于农业淡季的周数。这样，每户家庭因疟疾造成的年度经济损失为15.56美元，因所有其他疾病造成的年度经济损失为47.46美元。这分别相当于家庭年度净收入损失的6%和18%。尽管总体经济影响有限，但疟疾病例集中在一个重要的农业季节。在这个季节，5.6%的工作日因疟疾而损失。此外，不属于经济活跃人口的儿童在高传播季节因疟疾损失了10%的上学日。在估算疟疾的社会经济影响以及衡量疟疾控制干预措施的成本效益时，这些成本必须与家庭产生的直接支出（如治疗和交通费用）以及服务提供者的成本一并考虑。
