The first study cluster comprised of five family members from Anyang, China, who developed COVID-19 symptoms and tested positive by RT-PCR after acquiring the infection from the index case, an asymptomatic visitor from Wuhan who later tested positive 20 . Similar to the Diamond Princess, another study of an Argentinian expedition cruise ship found that 59% of the 217 passengers tested positive for COVID-19; 81% of those infected were asymptomatic virus carriers 24 . When assessing public health risks raised by asymptomatic COVID-19 cases it is important to determine whether the infectivity varies between asymptomatic, presymptomatic and symptomatic individuals. Since this also indicates a higher incidence of asymptomatic infections in younger people, it needs to be examined whether this group, especially children, could silently, yet efficiently, contribute to the spread of COVID-19.
