On the left, it shows mobility indicators in the form of traffic through retail and recreation venues across a number of major economies. The COVID-19 pandemic has depressed activity, forcing people to stay home to stop the spread of the virus. These mobility indicators can show if the general public is on the move again and in which economies, meaning consumer activity should pick up in those areas, or if they are still suffering from high infection rates and lockdowns, forcing mobility down and leading to low economic activity.
On the right, it shows the 7-day moving average of the share of COVID-19 tests that are positive across different regions. This metric measures the severity of outbreak since a number of developed economies are cutting back on the number of tests, which would result in reduction in confirmed cases. It can also help us understand the spread of the virus. When the positive rate is rising in a region, this can suggest the virus is actually spreading faster than the growth seen in confirmed cases.
