- Contact tracing is an essential component of
public health surveillance. It is however, labor-intensive
and expensive to carry out. Contact tracing has been
difficult to execute in several countries, and no impact
analyses based on empirical data have been conducted to
estimate its impact on COVID-19 mortality. We looked
on the efficacy of the current CDC definition of a close
contact, as well as the distribution of untraced secondary
cases. Using latest COVID-19 transmission estimates, we
show that fewer than 1 in 5 instances will result in
untraced cases.
