Followed your conversation, good point raised well my contribution is this, when you look at web based doctors consultation/treatment you find out that it lacks efficiency as much as physical consultation each have its own merit and demerit apparently, but ain't we looking at maximizing health care delivery to ensure a patient gets the best? It's also wrong to classify any illness as being small or minor although I understand the context in which that phrase was used but we can't rule out the importance of physical observation. Now back to the original post/content I feel most hospitals have enough meaures/ tech put in place to reduce spread of disease. Notwithstanding health care delivery comes with its own hazard been so since time in memorial. What we can do is come up with more measures/practice to fasten and enhance the ones already in place, my 2cent.
