A study conducted in China says wearing face masks at home greatly reduces a person’s risk of catching the-- a major escalation from the most common advice on the cloth coverings, which is that they should be worn in public when social distancing can’t be practiced.

Wearing masks really wasn’t protective after the symptoms started. “This study confirms the highest risk of household transmission being prior to symptom onset, but that precautionary [non-pharmaceutical interventions], such as mask use, disinfection and social distancing in households can prevent COVID-19 transmission during the pandemic,” said a news release from BMJ Global health, the medical journal that published the study., the risk of passing the virus quadrupled, the study says.
