You are write that the from number is unknown, but it can easily be larger. If a person is not tested and dies and is still not tested, they could have died from the disease without it being recorded. Unless every single death is being tested and every single test is 100% accurate, it is possible to be larger. I don't know whether it's plausible, but it's definitely possible.
