I think there is information explored on covid-19 especially using WhatsApp platform. It is like what happened in 1980s and 1990s during the advent of HIV and AIDs, everyone jumped on the bandwagon to misinformation until many got fatigued of information overload.
I think credible sources should be WHO and government official channels like ministry of health or government spokesmen and women.
Therefore, trustworthy information should be original, authentic, reliable from a source which one can verify.
