This appears to be the definitive paper on prevention and treatment of viral infection of all kinds, particularly including coronavirus. Note that continuous high doses of vitamin D are excellent for prevention and high dose vitamin C appears to be the most important once infected. Many other vitamins, minerals, fats, immune enhancers, coronavirus specific treatments, general anti viral approaches and other important related compounds are also described.

Abstract
An outbreak of a novel coronavirus (COVID‐19 or 2019‐CoV) infection has posed significant threats to international health and the economy. In the absence of treatment for this virus, there is an urgent need to find alternative methods to control the spread of disease. Here, we have conducted an online search for all treatment options related to coronavirus infections as well as some RNA‐virus infection and we have found that general treatments, coronavirus‐specific treatments, and antiviral treatments should be useful in fighting COVID‐19. We suggest that the nutritional status of each infected patient should be evaluated before the administration of general treatments and the current children’s RNA‐virus vaccines including influenza vaccine should be immunized for uninfected people and health care workers. In addition, convalescent plasma should be given to COVID‐19 patients if it is available. In conclusion, we suggest that all the potential interventions be implemented to control the emerging COVID‐19 if the infection is uncontrollable.
