it's like so welcome now a professor dr michael meyer herman from the helmholtz center for inspection research and colleges like he and other experts will be advising german politicians before they discuss additional measures to contain the rise in infections professor very welcome describe to us the current situation right now in germany. well as you just described we have strengthened lock down since the center 16 and the fact that we saw is mostly because of fluctuations during the christmas and new years time we had dramatic dramatic changes in the testing frequency so we were not able actually to interpret the data correctly there now it's coming back to normal and we see a slowly became number of infections over time so the good news is that the lockdown obviously helps there is some effect that we can observe but it is comparatively low so that the numbers go down rather slowly and we estimate that we are running with a reproduction number of 9 or something in this range and so that we will take months in order to bring down these numbers into a reasonable range always you like
