Everywhere in the world, people with symptoms are being advised to call a specific line before going to the hospital. In Portugal this line is SOS 24. This happens because by going to a hospital, people with symptoms who are infected might contaminate others and, if they're not infected, they might become, just by interrupting the quarentine.
Lines are clogged with calls from people who either have symptoms that do not match COVID-19 ones, or others who ask just plain stupid questions (https://observador.pt/2020/03/14/a-que-horas-fecha-o-norteshopping-as-chamadas-que-entopem-a-linha-saude-24/). People with real symptoms might have to wait for hours on end for their calls to be picked up, which might accelerate their panic and lead them to visit the hospital.
On twitter these last few days I've seen many portuguese doctors, nurses and pharmacists offering to answer questions posed to them there, to stop people from calling SOS24 unless their symptoms are 100% matching COVID-19 ones. Each person thinks their situation is very unique: "i don't have fever, but I have a cough, am I infected?", etc.
My idea is: a platform where doctors, pharmacists and nurses would put their profiles - ideally with a link to somewhere online which proved they really are what they say they are (hospital webpages, or CVs, of linkedin - and allow people to reach out to them in order to ask questions that they would otherwise call health lines to do so. I think people will always try to call health lines, but if they're waiting in line ~4hours for their call to be picked up, they might as well post a question on this website and see what a certificate health professional has to say.
I think this should be easy to build: first, a simple page with "I'm a doctor who wants to help" and a "post a question" for random users. Then, we would either round-robbin the questions that came via each professional in the platform or we would allow people to ask specific profiles of professionals available.
