The other cases were found in Kirehe and Rwamagana districts in the Eastern Province and Rubavu district in the Western Province, said the daily update of the Health Ministry.
The new cases brought the national tally to 5,312. The total recoveries and deaths rose to 4,974 and 41 respectively, with seven new recoveries and one more death reported over the past 24 hours.
The outbreak in Kigali’s prison came after Health Minister Daniel Ngamije on Monday revealed 13 cases in Rwamagana’s prison.
At that time he said the government is going to tighten measures in places with high concentration of people, such as markets, parks and prisons, until a vaccine is introduced.
