#MLHU is investigating a cluster of COVID-19 cases and there is the strong probability that the Omicron variant of the virus is involved. #LdnOnt #Middlesex /1

MLHU was advised last evening of two COVID-19 cases who screened positive for “S gene target failure” (SGTF) which is a marker for the Omicron variant. These two individuals are amongst a cluster of cases linked to travellers who arrived in London from Nigeria in late November./2

It's important to note that officials are still awaiting Whole Genomic Sequencing of the samples; however, with the travel history and the laboratory screening results, the likelihood of an Omicron cluster is very high. /3

Through its case investigations, MLHU has been able to identify at least 30 COVID-19 cases which are associated with this cluster of suspected Omicron cases. The number of high-risk close contacts continues to increase and is expected to exceed 100. /4

All positive COVID-19 cases and high-risk contacts associated with this cluster are considered to be persons under investigation (PUI) for Omicron. /5

So far, cases associated with this cluster have been linked to several schools and childcare centres; MLHU will be notifying these communities today. /6

This cluster of cases has also been linked to an outbreak at a church called God’s Favourite House on Dearness Drive in south London. The investigations are on-going and additional cases are likely. /7

MLHU continues to follow up with PUIs and close contacts and is advising anyone who is contacted by MLHU case investigators to follow their direction and guidance. /8

Please continue to monitor yourself for signs and symptoms of COVID-19 and seek testing immediately if any develop; it’s also very important to stay home and quarantine until test results are received. 9/9
