A serological survey was carried out in Monteria (500 000 population), a mid-size city in Colombia. An overall prevalence of 55.3% (95% confidence interval, 52.5%-57.8%) was found among a sample of 1.368 people randomly selected from the population. Test positivity was related to economic characteristics with the highest prevalence found in the most impoverished areas, representing 83.8% of the city's population. We found a prevalence that might be associated with some important level of population immunity.
在哥伦比亚的中型城市蒙特里亚（人口50万）开展了一项血清学调查。在从该城市随机抽取的1368人的样本中，总体患病率为55.3%（95%置信区间为52.5%-57.8%）。检测阳性与经济特征相关，在最贫困地区患病率最高，这些地区人口占该市人口的83.8%。我们发现的患病率可能与一定程度的人群免疫力有关。
