Chief medical officer warns of tighter restrictions to curb transmission

Wales’ Chief Medical Officer has warned that Alert level 1 restrictions may have to be implemented during the next 21-day review cycle as cases rise.

Frank Atherton made his comments in a statement, saying that it was essential to watch the evolving public health picture very carefully in the coming weeks, and that it may be time to consider further restrictions in order to protect the vulnerable and reduce prevalence.

Cases of COVID-19 and test positivity rates have continued to increase, and Wales is experiencing an exceptionally high rate of community transmission that is not falling in line with modelling expectations.

He has asked Public Health Wales and the Joint Biosecurity Centre to undertake further assessment as to why the community rate in Wales is higher than in other UK nations and why it is not falling as predicted.

As well as considering whether the mistake at a lab in England – which meant that people in the south-east of Wales were given false-negative results – could have contributed to the rise, he says that other factors, including the possible impact of increased transmissibility of the Delta sub-lineage AY.4.2 require further investigation.


“I note with concern the rise in case rate in the over 60s age group and rises in hospital admissions. This is likely to reflect both transmission from younger to older age cohorts and an effect of waning vaccine immunity.

“The NHS has been under sustained pressure for an extended period.  Although the COVID-19 contribution is much less than was seen in previous waves, COVID-19 bed occupancy rates are rising by around 10% per week so we can expect further direct COVID-19 pressures to accrue as long as community rates remain high.”

“Our better understanding of high secondary attack rates within households brings into question the current policy of non-isolation of household contacts.

“There would be risks in reversal of this policy including loss of essential staff, reduced public confidence, and undermining of the centrality of vaccination as a protective measure.

“I therefore support the modification of this policy to require vaccinated household contacts and 5- to 17-year-old household contacts of a positive case to self-isolate pending receipt of a negative PCR test result and to remove the requirement for a day 8 PCR test.”

Additionally, he said: “I support increasing vaccine uptake (including boosters) as the most important measure in mitigating the health impacts of COVID-19.

“Discussions have been held with the JCVI on the best interval between the second dose of the vaccine and the booster.
“I also support any reinforcement of the range of measures that can be used to encourage and support working from home as a way of reducing transmission of the virus.

“The UK Alert Level remains at UK Level 3 but is trending towards UK Level 4. We should watch the evolving public health picture carefully over the coming weeks and Ministers may need to consider a move towards a more comprehensive set of Welsh Alert Level 1 restrictions during the next 21-day review cycle.”

Are you proud of your bigotry or so you wear it lightly?

It would be marginally less pathetic if you had even attempted to put that in Welsh.

Maybe 75000 unmasked supporters at the Wales v NZ match, trains and pubs around central Cardiff might be considered a greater risk? English tourists I met in N Wales last week kept to the mask rules properly.

Noble sentiment, but the raison d’être of this comments section is for people to trade apocryphal tales of maskless plague ridden sais vermin

I don’t mind wearing a mask where I have to — although if a mask mandate made much of a difference one would expect to see it reflected in the stats between Wales and England. But Alert level 1 means that only extended households can meet in private homes indoors. I’m not prepared to give up my freedom of association now that the risk of mass death has been alleviated by vaccinations (and the continuing booster programme). I doubt that many others will be, either. “Breakthrough” infections occur, they can be unpleasant, but they are not worth losing our civil… Read more »

I haven’t any time or sympathy for any ‘administration’ across the UK. There should have been a plan to open schools with caution and to support with the opening of shops and small hospitality services. The borders (UK) are fully open, festivals and music events have started since July, Theatres and cinemas are open together with swimming centres and other large congregational arenas – not to mention our national stadium! The whole ‘plan’ (sic) is utterly and completely chaotic! It is now time to invest finance in protecting the very elderly and the extremely vulnerable and let everyone else get… Read more »
