All confirmed cases are said to have mild symptoms and have been asked to isolate at home.
Test and protect teams are in the process of contacting anyone who visited the premises at the time the first positive case was there and asking them to remain vigilant for signs and symptoms.
They have carried out a risk assessment and said they believe the risk of onward transmission to be low.
NHS Fife deputy director of public health, Dr Esther Curnock, said: “Contact tracing is a tried and tested method of breaking the chains of transmission for communicable viruses such as Covid-19.
“It is important that anyone experiencing the well-established symptoms of Covid-19, such as a high temperature; a new, continuous cough; or a loss or change to your sense of smell or taste, arranges to be tested using the UK Government Citizens’ Portal or by calling 0800 028 2816.”
