Between 20 and 30 people have been traced by NHS Fife after coming into contact with someone with coronavirus.
More than 30 staff have been recruited to the region’s contact tracing team and it is hoped that will rise to around 50 by the end of the month.
NHS Fife was one of three health boards to test the system now being rolled out nationally under the Scottish Government’s test and protect programme.
The policy allows anyone in Scotland to be tested if they develop covid-19 symptoms, including a high temperature, a new and continuous cough or a loss or change to their sense of smell or taste.
The close contacts of those testing positive, either at a UK Government testing site or via a home testing kit, are now being traced to limit the spread – which is expected to gradually increase with the easing of lockdown measures.
More than 700 people have been traced across Scotland.
NHS Fife said its figure would depend on how the Scottish Government interpreted the data but that it was fewer than 30.
It said it had rapidly expanded its contact tracing team and had completed staff training in a new system aimed at tracking people down faster and on a much larger scale than before.
They said the work was also helping to build an informed picture of the prevalence of the virus nationally.
Further staff will be recruited in line with Scottish Government guidance as needed.
NHS Fife director of public health Dona Milne said: “Effective contact tracing is a tried and tested method of breaking the chain of transmission for communicable diseases like covid-19.
“By identifying those who have come into close contact with individuals who have tested positive for the virus, we can provide the support and advice to prevent the virus being spread further.
“Contact tracing is most effective when individuals take the right steps to protect their families, friends and the community by self-isolating.
“This means maintaining distance from other family members wherever possible, not leaving the house for exercise or work and not visiting the shops for food or other essential items.
“Crucially, we know that those carrying covid-19 are often most infections in the first few days after symptoms develop so it is important that people isolate themselves immediately rather than waiting until they have received a positive result.
Ms Milne said contact tracing did not negate the need to practice physical distancing, good hand washing and environmental hygiene such as cleaning surfaces, door handles etc.
