For around 4 million people in England and Wales, April offers a chance of freedom as UK government guidance for the clinically extremely vulnerable to remain at home comes to an end. 

For some, this day has been a long time coming. One of those is Chris Olivotos, 54, an award-winning cameraman. 

He's braved war zones and hostile environments, but a kidney condition meant he had to take cover from COVID-19 when ordered to do so. Since then he's been shielding at home.

"When you're in a hostile environment, you sort of know what to look out for," he tells CGTN Europe. "You know the enemy, you know what you can and you can't do – but this is the invisible enemy, you can get it anywhere."

It's been a difficult few years for Olivotos. First he was diagnosed with his kidney condition, then he lost his job and has not qualified for any benefits during lockdown. 

His wife, who worked in retail, was also unable to work during the pandemic, as that would have posed too great a risk. 

As someone used to the adrenaline of war zones and broadcast deadlines, Olivotos has found his new reality of enforced time at home hard to adapt to, or use constructively.

"It's very, very difficult," he says. "You start out with a bit of motivation – 'I want to do this, I want to do that, because I've got free time' – but it really hits you hard at one point.  

"It takes its toll both mentally and physically, it's really difficult to keep motivated. It's horrendous – I just can't wait until this is over." 

For Olivotos and millions of others in England and Wales, the stay-at-home order has now been lifted. That's not the case throughout the UK, where each nation has devolved powers to adapt its own COVID-19 protocols. 

However, those who have been shielding in Scotland and Northern Ireland are expected to be granted the same level of freedom later in the month. 

Meanwhile, the Welsh government has given further guidance on its reopening plan, with outdoor hospitality and attractions allowed to operate from the end of April.
