Yes, they need to keep us captivated by the news about the so called Delta strain in case we all get too complacent. After all summer in Europe, flu type viruses at the minium. We can't have that. Too many people enjoying summer and looking forward to the end of the restrictions in July (in the UK anyway). I wonder how long all that bonhomie will last?I believe the established main theme for this Summer are the mutants/variants strains. That Delta strain is the bridge between spring and autumn lockdowns.
Because summer on the northern hemisphere just doesn’t provide any viruses good enough to keep the false cases up high. So, Delta is the filler, the amalgam to bridge both periods in order to keep up the charade.
