Two types of Omicron classified as Covid variants of concern in UK
Two types of the Omicron known as BA.4 and BA.5 have been labelled as variants of concern in the UK after new evidence on their growth, officials have revealed.
The wave of Omicron that hit the UK over the winter involved a form of the virus known as BA.1, with the sub-lineage BA.2 driving a subsequent wave in spring 2022.
While the latest data from the Office for National Statistics, released on Thursday, reveals that BA.2 remains dominant in the UK, the UK Health Security Agency (UKHSA) has revealed that two further Omicron sub-lineages, BA.4 and BA.5, have been added to the list of “variants of concern”. BA.4 and BA.5 are currently fuelling a new wave of Covid in South Africa.
Dr Meera Chand, UKHSA director of clinical and emerging infections, said the reclassification 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,” she said.
“UKHSA is undertaking further detailed studies. Data and analysis will be released in due course through our regular surveillance reporting.”
According to the UKHSA, as of Thursday there had been 115 confirmed cases of BA.4 and 80 cases of BA.5 in the UK. However, a report by the agency reveals modelling suggests they have a growth advantage over BA.2, including in the UK. In other words they could end up outcompeting the current dominant form of the coronavirus.
While the report cautions there is a higher degree of uncertainty, a preprint from a team including Prof Tulio de Oliveira, director of the Centre for Epidemic Response and Innovation at Stellenbosch University, suggested BA.4 and BA.5 appear to have a similar growth advantage over BA.2 as it had over BA.1.
Stricter curbs in Shanghai after fresh cases reported
Shanghai announced its first new Covid-19 cases outside quarantined areas in five days on Friday and imposed stricter curbs in two districts, but did not signal any change to the planned end of a prolonged city-wide lockdown on June 1.
The commercial hub of 25 million, in its seventh week of lockdown, has been slowly allowing more people to leave their homes in recent days, with many residential compounds issuing passes for brief walks or trips to the supermarket.
But in a sign of the challenges of China's "zero COVID" policy - at odds with the resumption of normal life in the rest of the world - authorities in Shanghai's Qingpu said on Friday it had sealed off and disinfected several places and tested more than 250,000 residents after discovering three cases.
Another district, Hongkou, on Friday afternoon ordered all shops to shut and residents to stay home until at least Sunday as it plans to carry out mass testing. It did not say why it had taken the action.
"Our district will carry out three consecutive rounds of PCR tests for everyone," authorities in Hongkou, home to more than 750,000 people, said on its official WeChat account.
"During this screening, all supermarkets, street-side shops must stop operations, everyone should not leave their homes."
