The median time is only around 5 days according to WHO[0]. The time from infection to hospitalization (when the case is bad enough) however has a longer median time which I have seen claimed to be around 11 days, but I can't find a good source. But it makes sense that we are seeing the longer lag when countries are only testing people with severe symptoms.
