Researchers have detected tiny airborne particles containing RNA from SARS-CoV-2, the virus that causes COVID-19, both inside and outside of rooms in which infected people were self-isolating at home.<\/p>\n
This finding suggests that airborne transmission beyond the isolation rooms in homes may pose a risk of infection to other home occupants.<\/p>\n
The study, in Annals of the American Thoracic Society<\/a><\/em>, is the first report of household air contamination with SARS-CoV2 RNA under typical daily living conditions when a household member is infected. Airborne transmission in crowded living conditions<\/a> may be one reason for higher rates of COVID-19 infection among people with lower incomes.<\/p>\n
“Risk of infection from larger respiratory droplets that rapidly settle onto surfaces, typically within two meters of the source, can be reduced by hand-washing, social distancing, and face masks<\/a>, but the tiny respiratory particles that stay suspended in air for hours, require air filtration, ventilation, or better masks for prevention,” says lead author Howard Kipen, a professor at Rutgers School of Public Health and director of Clinical Research and Occupational Medicine at the Environmental and Occupational Health 糖心视频s Institute.<\/p>\n
Additionally, in four of the homes other residents were also positive or had symptoms.<\/p>\n
“Our indoor air sampling data clearly demonstrated that measurable airborne SARS-CoV2<\/a> RNA was present in the air in the homes of most infected people, not only in the isolation room, but, importantly, elsewhere in the home,” Kipen says.<\/p>\n
