Omicron BA.4 and BA.5 designated as variant of concern by UKHSA
The UK Health Security Agency (UKHSA) has elevated the classification of the COVID-19 variants Omicron BA.4 and Omicron BA.5 to variants of concern (VOCs) on the basis of observed growth.
As of 17 May, 115 cases of BA.4 and 80 cases of BA.5 have been confirmed in England and the latest UKHSA variant technical briefing was published yesterday.
Whilst Omicron BA.4 and BA.5 are in the early stages of growth in the UK, analysis of the available data suggests that they are likely to have a growth advantage over the currently-dominant Omicron BA.2 variant.
There can be several reasons for growth advantage, but in the case of BA.4 and BA.5, laboratory data suggests a degree of immune escape which is likely to contribute.
Dr Meera Chand, Director of Clinical and Emerging Infections at UKHSA, “said: The reclassification of these variants as variants of concern reflects emerging evidence on the growth of BA.4 and BA.5 internationally and in the UK.
“Whilst the impact of these variants is uncertain, the variant classification system aims to identify potential risk as early as possible.
“UKHSA is undertaking further detailed studies. Data and analysis will be released in due course through our regular surveillance reporting.”
UK Covid Alert Level has moved from level 4 to level 3
“Based on advice from UKHSA, we the UK Chief Medical Officers and NHS England Medical Director have recommended to ministers that COVID Alert Level should move from level 4 to level 3.
“The current BA.2 driven Omicron wave is subsiding. Direct COVID-19 healthcare pressures continue to decrease in all nations and ONS community positivity estimates continue to decrease.
“We would like to thank healthcare staff for their remarkable efforts during a challenging time. Whilst it is reasonable to expect the number of cases to increase due to BA.4, BA.5 or BA2.12.1, it is unlikely in the immediate future to lead to significant direct COVID pressures. This will continue to be kept under review.”

FIRST MINISTER TESTS POSITIVE FOR COVID-19
First minister Nicola Sturgeon has tested positive for Covid
In a social media post last night, the first minister wrote: “Unfortunately I’ve tested positive for Covid this evening after experiencing mild symptoms.
“In line with Scottish government guidance, I’ll work from home over next few days, and hopefully be back out and about later next week.”
The First Minister attended a number of engagements in Washington DC this week and held a meeting with Sinn Fein’s Michelle O’Neill in Bute House yesterday.
