Abstract

Monkeypox virus (MPXV), a close relative of Variola virus, is a zoonotic virus with an unknown reservoir. Interaction with infected wildlife, bites from peri-domestic animals, and bushmeat hunting are hypothesized routes of infection from wildlife to humans. Using a Risk Questionnaire, performed in monkeypox-affected areas of rural Democratic Republic of the Congo, we describe the lifestyles and demographics associated with presumptive risk factors for MPXV infection. We generated two indices to assess risk: Household Materials Index (HMI), a proxy for socioeconomic status of households and Risk Activity Index (RAI), which describes presumptive risk for animal-to-human transmission of MPXV. Based on participant self-reported activity patterns, we found that people in this population are more likely to visit the forest than a market to fulfill material needs, and that the reported occupation is limited in describing behavior of individuals may participate. Being bitten by rodents in the home was commonly reported, and this was significantly associated with a low HMI. The highest scoring RAI sub-groups were 'hunters' and males aged ≥ 18 years; however, several activities involving MPXV-implicated animals were distributed across all sub-groups. The current analysis may be useful in identifying at-risk groups and help to direct education, outreach and prevention efforts more efficiently.

摘要

猴痘病毒(MPXV)是天花病毒的近亲,是一种宿主不明的人畜共患病毒。与受感染野生动物的接触、家畜的叮咬以及丛林肉捕猎被认为是野生动物向人类传播感染的途径。通过在刚果民主共和国农村猴痘感染地区进行的风险问卷调查,我们描述了与猴痘病毒感染假定风险因素相关的生活方式和人口统计学特征。我们生成了两个指数来评估风险:家庭物质指数(HMI),作为家庭社会经济地位的指标;以及风险活动指数(RAI),用于描述猴痘病毒从动物向人类传播的假定风险。基于参与者自我报告的活动模式,我们发现该人群中人们为满足物质需求而去森林的可能性高于去市场,而且所报告的职业在描述个体可能参与的行为方面存在局限性。在家中被啮齿动物咬伤的情况较为常见,且这与低家庭物质指数显著相关。风险活动指数得分最高的亚组是“猎人”以及年龄≥18岁的男性;然而,涉及与猴痘病毒有关动物的若干活动分布在所有亚组中。当前的分析可能有助于识别高危人群,并有助于更有效地指导教育、宣传和预防工作。
