There is some talk of a "summer Covid wave" at the moment. We all seem to know someone who has had it lately, or a friend who has been off sick.

But have cases really gone up and are there any new variants we should be worried about? What else do we know right now?

Is there a spike in infections?

Possibly, but it is difficult to tell.

We do know there has been a very small increase in the number of people being admitted to hospital with Covid.

The number went up to 3.31 admissions per 100,000 in the week to 16 June, compared with 2.67 per 100,000 in the previous week.
