Data gathered by the Mental Health Commission shows "a notable decrease" in the total number of suspected and confirmed cases of Covid-19 in mental health services across the country.
There are more than 3,900 mental health patients and residents in 181 mental health facilities nationwide.
However, the commission has expressed concern that as of last week some mental health staff were waiting for Covid-19 test results, despite the introduction of guidance over a month ago that required all staff to be tested.
Thirty-two out of 181 services reported that they were awaiting the test results of one or more staff.
The commission also says some services remain confused over which public health guidance document they should be following for the prevention and management of the virus.
It says that the Health Service Executive has since advised that separate advice was in development for approved centres that take acute admissions.
The CEO of the Mental Health Commission has recommended that standardised guidance be updated to provide certainty for services around different protocols and processes and how they might change as restrictions are lifted.
John Farrelly has called for a qualitative question to each service on current processes for new admissions delivered a variety of responses, rather than one consistent approach.
