疟疾死亡率和发病率是评价疟疾防治效果的重要指标。只有当大多数疟疾病人到医院或保健中心求医时,才能从这些单位得到准确的死亡率和发病率资料。但在热带非洲大部分地区,患病儿童很少去医院看病,因此需要一个有效的监测系统以了解疟疾死亡率和发病率。作者曾在冈比亚农村通过主动病例侦查,发现每周一次访问检出的疟疾现症病人是每月访问一次的4.1倍。因为半免疫的疟疾患者症状短暂,因此每周一次访问可能有遗漏,为此对每周一次和每日一次访问作了比较。
Malaria mortality and morbidity are important indicators for evaluating the effectiveness of malaria control. Accurate data on mortality and morbidity can be obtained from these units only when most malaria patients seek medical advice at hospitals or health centers. In most parts of tropical Africa, however, sick children rarely go to the hospital for medical treatment, and an effective monitoring system is needed to understand malaria mortality and morbidity. The author investigated active cases in rural Gambia and found that the number of malaria cases detected weekly visits was 4.1 times per month. Because of the brief symptoms of semi-immunized malaria patients, weekly visits may be missed, compared to weekly and daily visits.
