Dr. Patel said studies have shown that zinc is very effective at slowing the rate that similar viruses such as SARS (Severe Acute Respiratory Syndrome) and common cold (a type of coronavirus) replicate in the body.

"Our published studies have also shown that high doses of zinc can protect vital organs such as the heart, kidneys and liver against the damage caused by a lack of oxygen," Dr. Patel said.

The clinical trial has been fast-tracked to test whether receiving a daily injection of zinc chloride will benefit patients with coronavirus.
