From ABC 7, "LA doctor seeing success with hydroxychloroquine to treat COVID-19":

Dr. Anthony Cardillo said he has seen very promising results when prescribing hydroxychloroquine in combination with zinc for the most severely-ill COVID-19 patients.

"Every patient I've prescribed it to has been very, very ill and within 8 to 12 hours, they were basically symptom-free," Cardillo told Eyewitness News. "So clinically I am seeing a resolution."

Cardillo is the CEO of Mend Urgent Care, which has locations in Sherman Oaks, Van Nuys and Burbank.
