Of course if the outbreak becomes out of control, the efficiency of contact tracing is severly lowered. But even if the % of people linked to a cluster via contact tracing is low, it still has real value. If you couple it with genomics sequencing and pool testing, contact tracing (long) chains of transmission and help (re)directing resources where the cases truly are.
