Wearing face masks, disinfection and social distancing in households might help ward off COVID-19 spread among family members, an observational study suggests.

To explore if the wearing of face masks might help curb household transmission rates, a research team led by Zhang Ruiguang at the Union Hospital in Wuhan, China, questioned 460 people from 124 families in Beijing on their household hygiene and behaviors during the pandemic.

Each family had at least one laboratory confirmed case of COVID-19 infection between late February and late March 2020. The average family size was four, but ranged from two to nine, and usually comprised three generations.

Four behavioral and hygiene factors were significantly associated with secondary transmission of the virus. Diarrhea was associated with a quadrupling in risk; while close daily contact, such as eating meals round a table or watching TV together, was associated with an 18-fold increased risk.

Conversely, frequent use of bleach or disinfectants for household cleaning was 77 percent effective at stopping the virus from being passed on, and the wearing of a face mask at home before symptoms emerged, including by the first person to have them, were associated with a 79 percent reduction in transmission risk.

Interesting read,but hardly worth a mention since Chinese origin,based on common sense and non objective or qualitative questionnaire,hence,there are chances of easy manipulation of data as well.
