Research component for the novel coronavirus (COVID-19). Hydroxychloroquine have been found to be efficient on SARS-CoV-2 and reported to be efficient in Chinese COV-19 patients. It is evaluated that the role of hydroxychloroquine on respiratory viral loads. One study conducted by French, treatment of hydroxychloroquine with azithromycin was even more efficient for COV-19 elimination6.
