COVID: Nearly 50% of household transmission

New research shows that transmission of COVID-19 within a household can be as high as 50%, and that children play a “significant” role in the spread of the virus through the home.

The peer-reviewed study, published earlier this week in the Canadian Medical Association Journal, analyzed COVID-19 transmission in 180 homes in Ottawa, Ont. between September 2020 and October 2021, and found that after the first person in the household tested positive for COVID-19, 49.1% of those in the same household would then also have COVID-19. positive results.

Collectively, 239 people out of 487 people in the same household with someone with COVID-19 will later test positive for the virus.

Dr Maala Bhatt, associate professor of pediatrics at the University of Ottawa and lead author of the study, believes the study is a reminder that Canadians need to continue to take appropriate precautions.

She said in a newly posted information.

“Our most vulnerable children and our youngest children who have not been immunized are still at risk of contracting COVID.”

Maala also noted that this study was conducted prior to the emergence of the highly transmissible variant of Omicron, meaning that household transmission rates may be higher than in this study.

“While we are fortunate that the hospitals are not currently overwhelmed, emergency departments and admission rates are increasing, including among children,” Bhatt said.

“As substantial COVID-19 transmission continues in households and throughout communities, it is important that you continue to do what you can to keep yourself and those around you safe – Wear a mask while indoors, wash your hands, get vaccinated with all the doses for which you qualify. , stay home if you are sick, and limit close contact.”

While research indicates that adults are more likely to spread the virus to others in the home, research indicates that children are “an important source of transmission” and account for about a third of infections. passed on in the family.

“Children’s role in disease transmission deserves attention, as they are often asymptomatic or have mild symptoms,” the study notes.

“Addressing this gap in the literature will enable a more evidence-based approach to public health initiatives, as COVID-19 pandemic control strategies often impact lives.” of children and adolescents, as well as negatively impacting their overall health.”
