Data/reporting scope could be made anonymous and more local; on a city/town level (e.g. "Dec 22, 2019 | Severe flu case reported in X district of Wuhan (30°34'21.2"N 114°12'30.0"E) - potential for outbreak").

At high level of exposure, as you said, the Chinese gov may track down anyone behind such report, despite the anonymity. It may even block investigative entry/inquiry to the entire city. How do we solve that? I don't know but I suppose that, in the grand order of things and following this pandemic, we shouldn't be living in a world where any government is allowed to work against such public health efforts and get us into another quagmire that we could have simply avoided, which again rolls back to international relations, politics and trade and is tricky to solve but shouldn't stand in the way of trying these things out. We can't simply give up to the way the world is set up at any point in time.
