BACKGROUND: Distinguishing a recent from long-standing HIV infection is a critical step to reduce new infections in 2030. Therefore, this analysis determines the proportion of recent HIV infections among newly diagnosed cases and associated factors in the Amhara regional state between 2019 and 2021. METHODS: We got the HIV case-based surveillance dataset (July 2019 up to August 12/2021) from the Amhara Public Health Institute. Recent infection is an infection gained within the last 12 months as identified by Asante recency test kits. Logistic regression was carried out to identify factors associated with recent infection. Adjusted odd with 95% CI and a -value of < 0.05 was considered to declare significant associations. RESULTS: Out of 5,689 eligible cases, 3,129 (55%) recency tests had been performed. The proportion of recent HIV infection is 443 (14.2%, 95% CI: 13, 15.4%). High proportion of recent infections is reported from Bahir Dar city (23.3%), Central Gondar (17.7%), West Gojjam (16.5%), North Shewa (16.5%) and South Gondar zones (15.7%). Besides, the proportion of recent infection is high among clients aged ≥ 51 years (32.4%), illicit drug users (30.6 %), homelessness (28.5%), current commercial sex workers (27.9%), prisoners (21.1%), and among clients with invasive medical procedures (22.2%). Recent infection is significantly associated with females (AOR: 1.9, 95% CI: 1.2-3.1), secondary and above education (AOR: 2.1, 95% CI: 1.3-3.4), commercial sex workers (AOR: 1.8, 95% CI: 1.2-2.7), having contact with index case (AOR: 0.5, 95% CI: 0.3-0.8) and illicit drug utilization (AOR: 3.6, 95% CI: 1.1-12.4). CONCLUSION: In the Amhara region, the proportion of recent HIV infection is high with marked variation across sociodemographic characteristics. We identified the risk or preventive factors associated with a recent infection. Therefore, all HIV responders should target their prevention efforts toward hot spot areas and sub-populations to stop further transmission.
背景:区分近期和长期 HIV 感染是减少 2030 年新感染的关键步骤。因此,本分析旨在确定 2019 年至 2021 年期间在阿姆哈拉地区州新诊断病例中近期 HIV 感染的比例及其相关因素。
方法:我们从阿姆哈拉公共卫生研究所获得了基于 HIV 病例的监测数据集(2019 年 7 月至 2021 年 8 月 12 日)。最近的感染是指在过去 12 个月内通过 Asante 近期检测试剂盒确定的感染。采用 logistic 回归确定与近期感染相关的因素。调整后的比值比(OR)及其 95%置信区间(CI)和 a 值<0.05 被认为具有显著相关性。
结果:在 5689 名合格病例中,有 3129 名(55%)进行了近期检测。近期 HIV 感染的比例为 443 例(14.2%,95%CI:13%,15.4%)。巴希尔达尔市(23.3%)、中央贡德尔(17.7%)、西戈贾姆(16.5%)、北谢瓦(16.5%)和南贡德尔地区(15.7%)报告了较高比例的近期感染。此外,51 岁及以上的患者(32.4%)、非法药物使用者(30.6%)、无家可归者(28.5%)、目前的商业性工作者(27.9%)、囚犯(21.1%)以及接受侵入性医疗程序的患者(22.2%)中近期感染的比例较高。近期感染与女性(AOR:1.9,95%CI:1.2-3.1)、中等和高等教育(AOR:2.1,95%CI:1.3-3.4)、商业性工作者(AOR:1.8,95%CI:1.2-2.7)、与索引病例接触(AOR:0.5,95%CI:0.3-0.8)和非法药物使用(AOR:3.6,95%CI:1.1-12.4)显著相关。
结论:在阿姆哈拉地区,近期 HIV 感染的比例较高,且在社会人口学特征方面存在明显差异。我们确定了与近期感染相关的风险或预防因素。因此,所有 HIV 应对人员都应将预防工作的重点放在热点地区和亚人群上,以阻止进一步传播。
