The study included 101 households in Nashville, Tennessee and Marshfield, Wisconsin. All households have an indicative patient – a confirmed case by Covid-19. At the time patients indicated for the first time reported symptoms, no one else in their family had reported any symptoms.
The 101 designated patients (each in their own family) living with a total of 191 family contacts, 102 – or 53% – had a positive Covid-19 test result, according to the report.
Furthermore, the spread occurs “rapidly,” the authors write: “About 75% of the infections occur [were] determined within 5 days of patient onset index. “
The report notes that the patient’s age index doesn’t matter – adults, children and teenagers all spread the virus to others in their families.
Family groups have been reported to be an early source of the pandemic. The first case of human-to-human transmission in the country was between a husband and his wife in Chicago. One of the first coronavirus infections in New York, a man in his 50s, passed the virus to his wife and two children.
As early as February, the World Health Organization has recorded that most cases in China occur in family clusters.
She immediately isolated

At the same time, the authors added, everyone in the house should start wearing masks.

Similarly, 40% of patients are assigned to share a bedroom before becoming ill and 30% to share a bedroom after becoming ill.
The report also emphasizes the importance of quarantine. Less than half of coronavirus positive family contacts show symptoms when they are tested, and many report no symptoms for the next seven days. These individuals should be isolated to avoid infecting others.
