Late on Thursday three other persons visited Limassol general hospital and were being tested for the coronavirus Covid-19.
The three had recently returned to Cyprus from northern Italy.
Two are a couple; the third person exhibited flu-like symptoms, health officials said.
Three others were earlier quarantined at Limassol hospital and will be transferred to Troodos.
All three tested negative for Covid-19 but will remain confined as a precaution.
The state is using the government homes on Troodos as a first step after a couple of communities objected to having quarantine units in their areas.
