Overcrowded interior spaces, including private homes, are vulnerable to a particularly high level of COVID-19 transmission, new study found.
Published Monday in the Medical Journal JAMA, a comprehensive analysis of 54 individual studies with a total of 77,758 participants observed COVID-19 transmission from one person to another in a common home was 16.6 percent – higher than comparable coronaviruses such as MERS and SARS.
It also confirmed that domestic broadcasting rates could remain high even in areas where broader community broadcasting rates were low.

“The findings of this study suggest that considering that individuals with suspected or confirmed infections are isolated at home, households will continue to be a significant site for SARS-CoV-2 transmission,” the authors wrote.
Researchers also noted that virus transmission in homes was higher in symptomatic patients than asymptomatic patients.
Spread within homes was also higher among infected adults than among children, as well as between spouses instead of other family contacts.
COVID-19 infections blooming in homes could be due to a number of factors, namely close contact with others in an environment with circulating air. However, scientists note that it could also be attributed to structural differences in the spicy protein COVID-19 and higher viral loads in the nose and throat after the onset of symptoms.
Additionally, some COVID-19 infections tend to be mild and do not require hospitalization – facilitating spread among humans in a common space.
“This is yet another study that reminds us of how contagious the virus that causes Covid-19 is, and how difficult it is not to infect others if one lives in a crowded multiple dwelling,” said Leana Wen, a medical analyst at CNN. emergency physician and visiting professor at George Washington University Milken Institute School of Public Health, commented.
Wen did not participate in the study.
