PLOS Computational Biology published findings by Franco and colleagues regarding age differences in the probability of acquiring infection when exposed (susceptibility) and the probability of transmitting infection when infected (infectiousness) with SARS-CoV-2. 

This new computational method underlines the need to consider age-specific differences in susceptibility and infectiousness. Children seem to be 20%-50% less susceptible to SARS-Cov-2 infection than adults. The results also show a gradual decrease in susceptibility of adults, in line with the timing of the Belgian vaccination campaign.
