The health board has urged passengers who have sailed at certain times with Oban Sea Tour between June 19-21 to book a PCR test and self-isolate for 10 days.
The trips which have been affected by the transmission of the virus are the two-hour circular from North Pier that departed at 12.30pm on Saturday, June 19, as well as the two trips on the following day – at 12.30pm and 3pm on Sunday, June 20.
Passengers who were on the trip that departed the North Pier at 10am on Monday June 21 have also been asked to book a test and self-isolate for 10 days from the date of the tour.
In the announcement, the health board said: “NHS Highland’s health protection team has been notified of cases of Covid-19 linked to Oban Sea Tours.
“We would ask customers who took a tour with Oban Sea Tours on the following days and times (outlined above) to self-isolate for 10 days from the date of the tour and to book a PCR test whether you have symptoms or not.
