Recently a study conducted in South Korea founded that people are contracting the coronavirus from within their own households rather than contracting from outsiders.
A study published in the U.S. Centers for Disease Control and Prevention (CDC) on July 16 looked in detail at 5,706 “index patients” who had tested positive for the coronavirus and more than 59,000 people who came into contact with them.
According to the findings of the study, only 2 out of 100 infected people caught the virus from non-household contacts. On the other hand 1 in 10 had contracted the new coronavirus from their own families.
As per the age-wise, the rate of infection was higher within the household when the 1st positive cases were people ageing 20s or people in their 60s and 70s.
“This is probably because these age groups are more likely to be in close contact with family members as the group is in more need of protection or support,” Jeong Eun-kyeong, director of the Korea Centers for Disease Control and Prevention (KCDC) and one of the authors of the study, told a briefing.
Dr Choe Young-june, a Hallym University College of Medicine assistant professor who co-led the work said that children with age nine and under were least likely to be the index patient. Moreover, children with COVID-19 are mostly asymptomatic as compared to adults, thus making it harder to know index cases within children.
“The difference in the age group has no huge significance when it comes to contracting Covid-19,” said Choe. He added that there is less possibility that children will transmit the virus. However, he also said that to arrive at this hypothesis, their data is not sufficient.
Between January 20 and March 27, the study collected the data. This was the time when the new coronavirus was increasing exponentially. Further, this was the time when daily COVID-19 infection in South Korea was at the peak.
Total confirmed COVID-19 cases in South Korea accounts to 13,879. Total deaths reported due to the COVID-19 in SK accounts to 297. However, 12,698 people have recovered from the COVID-19 infection.
