They use this course of treatment and feel that it works very well. They see three stages that lead to problems with Covid. First is viral replication, of course. Ivermectin, zinc, and doxycycline are for that. Second, for some people, inflammatory processes get out of hand (cytokine storm). Aspirin as an anti-inflammatory can help with that. If a person is in a hospital, steriods can be a yet more-powerful help (prednisone). Third, some people progress to having microthrombosis (micro blood clots, such as in the lungs and other organs, which is what leads to lung and other organ damage in some people). Aspirin is a mild anticoagulant that can help. If a person is in a hospital, then other blood thinners that are yet more powerful can be used (warfarin, etc.).
