Sixty-eight people have been arrested in connection with the Buddhist-Muslim unrest, which has left 11,376 people homeless, the New Light of Myanmar newspaper reported.
In total, 163 incidences of violence have been reported in 15 townships, it added.
Previously the official death toll stood at 40.
The situation appears to have calmed since President Thein Sein on Thursday vowed a tough response against those behind the violence, which he attributed to "political opportunists and religious extremists".
Security forces fired warning shots on Wednesday to disperse rioters. But Muslim leaders have criticised the security forces for failing to stop the attacks.
