Car sharing has been identified by NHS Western Isles as a factor in the spread of Covid-19 in Uist.
Mild symptoms have also been identified as causing delays in people getting tested and self-isolating, allowing the outbreak to spread.
The health board has told people to avoid car-sharing with anyone from outside their household, and issued detailed guidelines for those who can’t avoid it, including those taking driving lessons.
The precautions include limiting the number of people in the vehicle, washing hands before entering and after leaving the vehicle, maintaining good ventilation and opening windows for the duration of the journey.
Car sharers are also advised to sit as far apart as possible and wear a face mask or covering for the duration of the journey.
Door handles and any other surfaces people touch in the car should be wiped down before and after the journey.
