WINNIPEG There is some homegrown evidence children may be less infectious when it comes to COVID-19 compared to adults, according to some local researchers. “There’s probably something going on here that’s biologically different about children and how they interact with the virus,” said Principal Investigator Dr. Jared Bullard, an associate professor of pediatrics and infectious diseases at the University of Manitoba (U of M). U of M researchers analyzed positive samples from 175 children – infants to age 17 – and 130 adults. They found the samples from children were half as likely to grow on cell culture and produced significantly less virus compared to the adult ones.

Lead investigator Dr. Jared Bullard, an associate professor of pediatrics and infectious diseases at the University of Manitoba, says the findings suggest child care workers, teachers and support staff may be at lower risk of becoming infected.

Children are less likely than adults to transmit SARS-CoV-2 (the virus that causes COVID-19) to others, revealed a new University of Manitoba-led research published in CMAJ (Canadian Medical Association Journal). Our findings have important public health and clinical implications, writes principal investigator Dr. Jared Bullard, associate professor, pediatrics/child health and medical microbiology/infectious diseases, Max Rady College of Medicine, University of Manitoba and associate medical director, Cadham Provincial Laboratory in Winnipeg, Manitoba.
