I hope this makes it on the front page. This might be a real solution to a large portion of the problem given that it is readily available, easy to manufacture, and prevents infection with less side effects than regular chloroquine. Large amounts of the population could be prescribed this as a prophylactic and prevent much of the spread from occurring even in high risk occupations. I would love to see the telehealth system used to send prescriptions for this to pharmacies everywhere for at risk workers.
