尽管过去十年中疟疾在全世界的发病率和死亡率都有了显著下降，但它仍然是一个严重的全球公共卫生问题。在哥伦比亚，在此期间，许多因素造成了疾病的持续传播，报告的疟疾病例数总体呈下降趋势，但出现了重大波动。尽管疟疾在流行病学上很重要，但很少有研究使用监测数据来描述哥伦比亚的疟疾状况。本研究旨在描述2010年期间向哥伦比亚国家卫生研究所（INS）公共卫生监测系统（SIVIGILA）报告的疟疾病例的特征。利用SIVIGILA 2010年的疟疾信息进行了一项描述性研究。计算了病例数、频率、比例、比率以及集中趋势和数据离散度的测量值。此外，还估计了年度寄生虫指数（API）以及2009年和2010年报告的变量之间的差异。2010年，SIVIGILA共记录了117，108例病例，全国API为每1，000名居民10.5例，上半年发生的病例较多。超过90%的病例报告在七个省（=州）：安蒂奥基亚：46 476（39.7%）;乔科：22 493人（19.2%）;科尔多瓦：20 182人（17.2%）;瓦莱：6 360人（5.4%）;瓜维亚雷：5 876人（5.0%）;纳里尼奥：4 085人（3.5%）;玻利瓦尔：3 590人（3.1%）。间日疟原虫约占病例的71%;恶性疟原虫约占28%;少数罕见病例由三日疟原虫引起。总体而言，男性（65%）的发病率高于女性（35%）。虽然约三分之一的病例发生在15岁以下的儿童中，但大多数病例发生在5岁以上的儿童中。种族分布情况表明，约68%的病例发生在混血儿和白人中，其次是23%的非洲人后裔，其余的（9%）发生在土著社区。超过一半的个案在早期便求诊，其中623宗为复杂个案，23宗为致命个案。然而，总体发病率上升，相当于流行病爆发，表明有必要加强预防和控制活动以及监测，以减少爆发的风险和随之产生的经济和社会影响。
Although malaria has presented a significant reduction in morbidity and mortality worldwide during the last decade, it remains a serious global public health problem. In Colombia, during this period, many factors have contributed to sustained disease transmission, with significant fluctuations in an overall downward trend in the number of reported malaria cases. Despite its epidemiological importance, few studies have used surveillance data to describe the malaria situation in Colombia. This study aims to describe the characteristics of malaria cases reported during 2010 to the Public Health Surveillance System (SIVIGILA) of the National Institute of Health (INS) of Colombia. A descriptive study was conducted using malaria information from SIVIGILA 2010. Cases, frequencies, proportions, ratio and measures of central tendency and data dispersion were calculated. In addition, the annual parasite index (API) and the differences between the variables reported in 2009 and 2010 were estimated. A total of 117,108 cases were recorded by SIVIGILA in 2010 for a national API of 10.5/1,000 habitants, with a greater number of cases occurring during the first half of the year. More than 90% of cases were reported in seven departments (=states): Antioquia: 46,476 (39.7%); Chocó: 22,493 (19.2%); Cordoba: 20,182 (17.2%); Valle: 6,360 (5.4%); Guaviare: 5,876 (5.0%); Nariño: 4,085 (3.5%); and Bolivar: 3,590 (3.1%). Plasmodium vivax represented ~71% of the cases; Plasmodium falciparum ~28%; and few infrequent cases caused by Plasmodium malariae. Overall, a greater incidence was found in men (65%) than in women (35%). Although about a third of cases occurred in children <15 years, most of these cases occurred in children >5 years of age. The ethnic distribution indicated that about 68% of the cases occurred in mestizos and whites, followed by 23% in Afro-descendants, and the remainder (9%) in indigenous communities. In over half of the cases, consultation occurred early, with 623 complicated and 23 fatal cases. However, the overall incidence increased, corresponding to an epidemic burst and indicating the need to strengthen prevention and control activities as well as surveillance to reduce the risk of outbreaks and the consequent economic and social impact.
