Outbreak control measures during COVID-19 outbreaks in a large UK prison consisted of standard (e.g., self-isolation) and novel measures, including establishment of: (i) reverse cohorting units for accommodating new prison admissions; (ii) protective isolation unit for isolating symptomatic prisoners, and (iii) a shielding unit to protect medically vulnerable prisoners.
Single-centre prospective longitudinal study (outbreak control study), implementing novel and traditional outbreak control measures to prevent a SARS-COV-2 outbreak. The prison held 977 prisoners and employed 910 staff at that start of the outbreak.
120 probable and 25 confirmed cases among prisoners and staff were recorded between March and June 2020 during the first outbreak. Over 50% of initial cases among prisoners were on the two wings associated with the index case. During the second outbreak, 182 confirmed cases were recorded after probable reintroduction from a staff member. Widespread testing identified 145 asymptomatic prisoners, 16.9% of the total prisoner cases. The cohorting units prevented re-infection from new prison admissions and the shielding unit had no COVID-19 infections linked to either outbreak.
Identifying and isolating infected prisoners, cohorting new admissions and shielding vulnerable individuals helped prevent uncontrollable spread of SARS-COV-2. These novel and cost-effective approaches can be implemented in correctional facilities globally.
在英国一所大型监狱的 COVID-19 疫情爆发期间,采取了标准(例如,自我隔离)和新型措施来控制疫情,包括:(i)为容纳新入狱囚犯而设立的反向队列单位;(ii)用于隔离有症状囚犯的隔离单位;以及(iii)保护易受感染的囚犯的隔离单位。
在爆发控制研究中,实施了新型和传统的爆发控制措施,以防止 SARS-COV-2 爆发。该监狱在疫情爆发时拥有 977 名囚犯和 910 名工作人员。
在 2020 年 3 月至 6 月的第一次疫情爆发期间,记录了 120 例疑似病例和 25 例确诊病例,其中囚犯和工作人员各占 50%以上的初始病例与索引病例有关。在第二次疫情爆发中,有 182 例确诊病例是在一名工作人员再次确诊后记录的。广泛的测试发现了 145 名无症状囚犯,占囚犯总数的 16.9%。队列单位阻止了新囚犯入院的再次感染,而隔离单位在两次疫情爆发中都没有与 COVID-19 相关的感染。
识别和隔离感染的囚犯、对新入院的囚犯进行队列隔离以及保护弱势群体有助于防止 SARS-COV-2 的不可控传播。这些新型且具有成本效益的方法可以在全球的惩教设施中实施。
