概括

孕妇的产前护理 (ANC) 访问可以有效地跟踪社区的疟疾趋势. 这种监测方法提供了有关疟疾的及时数据.

科学领域:

疟疾学疟疾学
公共卫生公共卫生
流行病学流行病学

背景情况:

孕妇参加产前护理 (ANC) 是撒哈拉以南非洲疟疾监测的关键人口.
了解疟疾传播动态对于有效的控制策略至关重要.

研究的目的:

评估ANC访问期间和一般社区中孕妇疟疾趋势之间的时空关系.
评估基于ANC的监测对监测疟疾负担的有用性.

主要方法:

在孕妇 (ANC) 中通过定量PCR检测到的疟疾寄生虫 (P. falciparum) 的比率与社区和卫生机构的儿童的比率进行了比较.
分析了不同监视数据源 (2016-2019) 之间的时空相关性和时间滞后.
在卫生机构数据上使用了一种新的热点检测算法 (EpiFRIenDs),并将结果与ANC数据进行比较.

主要成果:

ANC P. falciparum的发病率与儿童的发病率有很强的相关性 (PCC>0.8),有2-3个月的滞后.
对VAR2CSA的血清流行反映了疟疾趋势的下降 (PCC = 0.74).
在卫生机构中发现的60%的疟疾热点也使用ANC数据检测到.

结论:

在ANC访问中使用孕妇进行疟疾监测,提供了对时间趋势的当代见解.
ANC数据有效地捕捉了社区内的疟疾负担的地理分布.
基于ANC的监测是高传播环境中疟疾监测的宝贵工具.

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
