THE MOST recent research findings suggest that the SARS-CoV-2 Delta variant replicates at a much higher speed than the original virus, resulting in a higher viral load and infectiousness earlier on. Hence the unprecedented speed and reach of the Delta variant in populations make staying ahead of the virus more challenging and essential.
First of all, the Delta variant's spread places a higher demand on the system of finding, testing, tracing, isolating and supporting (FTTIS) for its aggressiveness – nearly real-time speed and scale.
