Measles Outbreak in Kigali Prison Controlled-Rwanda, 2010

Background: Measles is a highly infectious disease. In prison settings it can spread rapidly. In September 2010, health-workers in Kigali Prison’s Clinic in Rwanda reported a suspected outbreak of measles among prisoners. We investigated to confirm the diagnosis, establish the occurrence of an outbreak, identify the strain of measles virus involved and recommend control measures.

Methods: We conducted a descriptive study. A suspected case of measles was any one within the prison setting presenting with fever and rash from 1st July to 30th September 2010. A confirmed case was a suspected case with positive IgM test or epidemiologically linked to a confirmed case. We reviewed medical records of patients at the prison clinic, collected serum samples from 9 patients and tested for measles IgM. We also collected oro-pharyngeal specimens for viral identification and typing.

Results: Six samples tested positive for measles IgM. Paramyxovirus B3 type virus was isolated. In all 69 persons were identified as measles patients in the prison. Sixty three (91%) were adult prisoners and the rest were children of these prisoners. All patients presented with fever and rash. Fifty five (80%) presented with fever, rash and conjunctivitis. All patients did not know whether they were previously vaccinated against measles or not. 

Conclusions: Measles outbreak occurred in Kigali Prisons caused by Paramyxovirus B3. We recommended that patients be isolated, all prisoners and their children and all staff of the prison be vaccinated against measles. As a result, patients were isolated and treated, 4,538 persons comprising prisoners, their children and prison staffs were vaccinated and the outbreak was controlled.
