I'm not sure I get how the problem is related to WhatsApp. WhatsApp is a platform for (largely) private messaging among individuals or small groups. It's a SMS/Call replacement/enhancement. I wouldn't want health officials, or anyone else for that matter, to be monitoring what gets exchanged over WhatsApp to detect misinformation. This is not a platform problem, this is a "there's disinformation out there and individuals are spreading it problem", I think. This is different in my mind from semi-public/public platforms a-la Facebook, Twitter, etc.
