The public prosecutor’s office said 172 people had already been tried and convicted, without giving details.
Families and activists have criticized the trials as unfair, and say the sentences are disproportionate.
Thousands demonstrated across the Communist-run Island last July to voice anger over food and medicine shortages, price increases and the government’s handling of the pandemic.
The accused include 55 people aged 16-18, as people in Cuba can be prosecuted as adults from the age of 16.
The update came after a number of complaints by families and activists in recent weeks about the lack of transparency of the mass trials and the lengthy prison terms being given. END
