WHO. I think this is a reliable and updated source and as many people follow it, it is possible to contact scientists, medicals, engineers, biochemicals, virologists, infectologists, among others. Then you can ask questions, propose ideas, and then get reliable feedback.
However, i think it would be better if we create workgroups to discuss different alternatives. For example, the first group explained how is the pathway of the virus once it has reached the throat. How long stay there, before going into the lungs. Depend on this a second group could think of how we could destroy the crown that protects the virus once it has reached the throat. It is clear that washing our hands with soap we can destroy the crown and death the virus. But once it is into the body, how we could do it.
Third group could focus in to find out if the virus has a weakness. I mean maybe the low pH, the high temperature, the high CO2 concentration or if maybe there is another virus that can beat it, without brings serious health problems to the pacient. And so on.. different groups working connected and under the WHO "inspection".
I think people would be happy feeling they can be useful. Also WHO could produce kids visual material about virus and of course coronavirus and the importance that kids keep the social distance and keep at home.
