That is the primary examine to show the advantages of prophylactic, or preventive remedy with both oral hydroxychloroquine or povidone-iodine throat spray in decreasing SARS-CoV-2 an infection amongst quarantined people residing in a closed and excessive publicity setting, mentioned lead writer of the scientific examine, Affiliate Professor Raymond Seet from the Nationwide College Hospital (NUH).
