It s privacy. Most landers do not inform Berlin of infected ppl. I know for sure 6 are in intensive care in Amburg bit the official stats said they had 2 intensive care. Moreover they exclude from the dead for corona those with other healt issue ( dead with corona, no for corona).@ VIW recruiting time!
I know that the Italians are shaking their head at our low numbers and think we are forging them in order to be low. However the official statement from the Robert Koch Institut (the scientists responsible for gathering information about the virus) is that every death where the person had the virus counts towards the overall death toll. The only possible difference I see regarding gathering the data is if Italy indeed also checks post mortem whether the corona virus was involved while we Germans probably don't do that.
The official German response from the Robert Koch Institut isn't btw that our healthcare system is so much better than your Italians but that we are lacking a few weeks behind in the curve. Germany is currently expecting the storm however we aren't in it yet.
Here is an article wondering about the low German fatality rate:

Our official data is indeed lacking a bit behind since the data has to get transimtted to the Robert Koch Institute which doesn't work fully automaticcally. However those are just some details.
