Experts say the toss-up between Level 3 and Level 2 could go either way for Auckland, and now there are calls for a major new targeted approach, including door-to-door testing where the virus could be lurking. Epidemiologist Michael Baker said the persistent numbers, plus the odd case popping up from nowhere, were signs the virus was still transmitting, RNZ reports. Teams should go door-to-door in areas of concern, checking for symptoms and asking to test people, offering a vaccination at the same time, he said. “It’s really down to that level of intensity… if we are really going to stamp out the virus in Auckland.” University of Auckland public health specialist Collin Tukuitonga supports the approach, saying the city is at a turning point.
