Covid: 'We don't know what the next variant will be'

Staff at Ealing Hospital in west London say they are seeing more patients admitted for various reasons testing positive with incidental Covid-19, with fewer needing hospital treatment primarily for the respiratory virus.

General medicine consultant Dr Harmandeep Singh said the vaccine played a large part in protecting people who would otherwise be vulnerable. One of his patients recovering from a leg infection had coronavirus, but was asymptomatic.

However, as restrictions are eased, concerns have been raised about the impact of possible future virus variants.
