‘The researchers found that household contacts of COVID-19 cases and individuals traveling with cases were both at elevated risk of infection. Additionally, the secondary “attack rate” (percentage of contacts who tested positive for SARS-CoV-2 infection) among household contacts was at least 11.2%. While attack rates were higher among older adults, the value for children—7.4% and 7.1% for children aged 0-9 years and 10-19 years, respectively—was higher than in younger and middle-aged adults—4.9%-6.1% for adults aged 20-29 years, 30-39 years, and 40-49 years. Individuals aged 0-39 years exhibited lower risk of severe COVID-19 than adults aged 40 years and older.’
