Social and family contact
Since 23 March the Government has asked people to only leave the house for very limited purposes and this has been extraordinarily disruptive to people’s lives.
In particular this has affected the isolated and vulnerable, and those who live alone. As restrictions continue, the Government is considering a range of options to reduce the most harmful social effects to make the measures more sustainable.
For example, the Government has asked SAGE to examine whether, when and how it can safely change the regulations to allow people to expand their household group to include one other household in the same exclusive group.29
The intention of this change would be to allow those who are isolated some more social contact, and to reduce the most harmful effects of the current social restrictions, while continuing to limit the risk of chains of transmission. It would also support some families to return to work by, for example, allowing two households to share childcare.30
This could be based on the New Zealand model of household “bubbles” where a single “bubble” is the people you live with.31 As in New Zealand, the rationale behind keeping household groups small is to limit the number of social contacts people have and, in particular, to limit the risk of inter-household transmissions.32
In addition, the Government is also examining how to enable people to gather in slightly larger groups to better facilitate small weddings.
Over the coming weeks, the Government will engage on the nature and timing of the measures in this step, in order to consider the widest possible array of views on how best to balance the health, economic and social effects.
