Recent Covid-19 wastewater figures have suggested the latest Omicron wave is tailing off.

Surveillance figures from the Institute of Environmental Science and Research showed a sharp decline in the week ending 21 January.

The viral load had dropped by more than half to 3.76 million genome copies per person per day, after apparently peaking in the first week of January at 8.46 million genome copies per person.

Last week, 7019 new cases of Covid-19 were reported and 343 people were in hospital with the virus.
