If over 70 but not not had a shielding letter there is no problem. If shielding people would come under the "Clinically extremely vulnerable category". If just over 70 it's the "clinically vulnerable category"
Clinically vulnerable’describes the wider group of people who have been identified as being more at risk from the new coronavirus but not so severely that they need to shield themselves.
The government doesn’t actually recommend that clinically vulnerable people follow any rules that differ from the universal social distancing guidance.
But these people are being told to follow thatguidancecarefully, and to take particular care to minimise contact with others outside of their household.
As discussed above, this group includes anyone aged 70 or older regardless of their medical conditions.
It also includes anyone who is under 70 but has health conditions including chronic mild to moderate respiratory disease, chronic heart, kidney or liver disease, chronic neurological conditions, diabetes or a weakened immune system because of conditions such as HIV and AIDS or medicines like steroid tablets.
This group alsoincludes pregnant womenand anyone classed as seriously overweight, with a body mass index of 40 or above.
