A new strain of Omicron is threatening a new wave of Covid infections as hospitals and healthcare supplies buckle under the weight of rampant flu and other respiratory diseases.
The Omicron BA.5 sub-variant, which was identified in April by South African labs, is rapidly overtaking the BA.2 variant, which caused a Covid case spike in March.
The BA.5 strain has a ‘transmission edge’ over BA.2 by being spreading more easily but crucially, it also defeats the immunity built up from vaccines and previous Covid infections.
