Antiviral efficacy of personal care formulations against Severe Acute Respiratory Syndrome Coronavirus 2.
BACKGROUND: Non-therapeutic interventions such as practicing good hand hygiene continue to be the mainstay of protection from SARS-CoV-2 and other emerging respiratory viruses.
METHODS: We have evaluated a range of commercially available personal care products including soaps, handwash liquids and alcohol-based hand sanitizers for antiviral efficacy against a clinical isolate of SARS-CoV-2 using internationally accepted standardized protocols at user-relevant contact time-points and product dilutions.
RESULTS: All the tested products resulted in 3 to 4 log reduction of SARS-CoV-2 titer.
CONCLUSION: Our data re-affirms recommendations by global public health authorities that proper hand hygiene can reduce SARS-CoV-2 viral load significantly which should likely limit spread of the contagion.
