A lot of people are looking forward to socialising with friends and family in gardens from 29 March. With some nice weather on the way, some BBQs and picnics and drinks in the garden sound great. Outdoor socialising in fresh air is safer than indoor socialising, but it's not 100% safe. Particularly if you're sat close together in a gazebo or tent! Ventilation and distancing are still things to think about if you have vulnerable people visiting, haven't been vaccinated yet, and just want to try to keep cases in the community low. At the local primary school 4 of the 7 year groups are isolating with multiple cases right now - it's still circulating, and passing on cases can put entire year bubbles and workplaces out of operation.
From the govt roadmap: "As soon as possible and by no later than Step 3 [May 17th], we will also update the advice on social distancing between friends and family, including hugging. But until this point, people should continue to keep their distance from anyone not in their household or support bubble."
