FRIDAY, October 30, 2020 (HealthDay News) – COVID-19 can spread like wildfire through a family, often by moving other people out of the house to take someone to a coronavirus home, new Research shows.
According to findings from the US Center for Disease Control and Prevention, more than half of people in families with COVID-19 patients contract the virus, usually within five days of the first patient developing symptoms.
A study with COVID-19 initially detected 101 people in the cities of Nashville, Tenne and Marshfield, Wis. Between April and September, according to a report published on October 30 in the CDC report. Morbidity and Mortality Weekly Report.
Those initial patients lived in their homes with a total of 191 others, and researchers took samples from others in the home to track infectivity of the COVID-19 coronavirus.
Researchers said that of those 191 secondary domestic contacts, 102 tested positive for coronaviruses – about 53%.
Four of these secondary infections (75%) occurred within five days of the first person becoming ill. During the seven days of follow-up, two-thirds (67%) of the infected household members reported symptoms of COVID-19.
A university news release said, “We noticed that after the first household member became ill, Dr. Carlos Grijalva, Associate Professor of Health Policy at Vanderbilt University Medical Center in Nashville, said the rapid detection of multiple infections in the home “Those infections occurred rapidly, whether the first sick household member was a child or an adult.”
Researchers found that COVID-19 spreads rapidly whether the age of the first patient spreads into a home. In the initial patients, 14 were aged 17 and younger, 65 were between 19 and 40, and 22 were 50 or older.
“Understanding that children can also serve as a vector within a home as a CD was an important finding to emerge from this CDC report,” Dr. Robert, an emergency physician at Lenox Hill Hospital in New York City Glater said.
Of the initial COVID-19 patients, approximately 70% reported spending more than four hours in the same room with one or more household members before becoming ill, and 40% stated that they were in the same room with others Also spend more time developing symptoms.
Similarly, 40% of the first patients stated that they slept in the same room with at least one other person before developing COVID-19, and 30% did so after falling ill.
The researchers stated that the data reveal the risk of asymptomatic transmission of COVID-19. More than half of the household members with confirmed infections reported symptoms at the time they tested positive, and a third reported no symptoms during the seven days of follow-up.
“These findings suggest that the transmission of SARS-CoV-2 within homes is more frequent, quicker and may originate from both children and adults,” the researchers concluded.
According to the study, Glitter said that identifying the home as a potential source of outbreaks is important to control the epidemic, as cases, hospitalizations, and deaths have been increasing significantly in the US over the past few weeks.
“To prevent transmission, it is important to emphasize the importance of self-isolation at home and to self-quarantine any potential domestic contacts,” Glatter continued. “Ideally, it should be with a separate bedroom and bathroom access if possible.”
Rapid antigen testing may help families coming to their home with COVID-19 to monitor transmission if they become widely available, he said.
“In addition, all household members must wear a mask in shared spaces within any house setting. These measures may reduce the ability of home transmissions,” Glatter concluded.
