Diolch, Dirprwy Lywydd. I formally move the amendment tabled in my name. I'd like to thank the Welsh Conservatives for bringing forward this very important debate, which I will be supporting, along with the Plaid Cymru amendments that I feel seek to strengthen the debate.

I've been calling for the wearing of face coverings to be mandatory on public transport particularly from the early days of the pandemic, following calls from my constituents who were key workers but not able to get on buses because public transport was running at only 25 per cent capacity, which was unsustainable. I did put this forward as a question to the First Minister, and I was pleased to see this suggestion adopted a day later.

We know for a fact that SARS-CoV-2 virus is spread by microdroplets making it effectively airborne. We also know that the disease can be spread by those not displaying any symptoms at all, and face masks can and do prevent the spread of COVID-19. We must heighten people's awareness and be consistent in our message and emphasise the importance of wearing a mask. Had the guidelines been adhered to, we may not be seeing local lockdowns as we are seeing now, and the only way we can ensure that people wear a mask is to mandate it.

There is evidence that the outbreaks we are seeing are caused by people returning from overseas and not self-isolating. And an entire county and beyond, as we've learnt today, of people have had their freedoms curtailed because of the actions of a few. Anyone travelling from overseas should have to quarantine in isolation for 14 days. It makes no sense that people can travel from COVID hotspots, told to isolate, but can, if they so wish, ignore the instructions, safe in the knowledge that nobody is checking. They are allowed to leave their homes to shop. It is also nonsensical that everyone in the household can carry on as normal—going to work, the supermarket or the pub. I believe that the Welsh Government needs to secure accommodation to enable travellers to quarantine in complete isolation, where food and medication is delivered to them and they are tested for COVID-19 at day 2 and day 9, regardless of whether they are displaying symptoms. And those returning to the UK who have the facilities to completely isolate from the remainder of their households can do so in their own homes, but would be subject to testing and regular random checks to ensure compliance. This is how it is done in countries that have successfully suppressed COVID—countries that haven't had any cases in over three months. And if we are to have any chance of suppressing a second wave, then we need to be tough.

Locking everyone down is unfair and is unnecessary. We need to isolate carriers and possible carriers and test them all, regardless of whether they are displaying symptoms. If we don't, this outbreak will continue to smoulder unchecked, flaring up when we least expect it. Lockdowns may well be necessary in future, but they need to be hyperlocal and strictly enforced. Caerphilly county is in lockdown, but its residents can still travel to work or go to the pub, so it is more of a partial lockdown.

If we are to get a handle on this, measures may need to be tougher, but they also don't need to be applied across the board. Our focus must be on identifying and isolating those infected with the virus, not locking everybody away—that's akin to chopping down the forest to prevent a fire. I urge Members to support my amendment and the motion. Diolch yn fawr.
