This is due to the large fraction of presymptomatic (and perhaps asymptomatic) transmission. Contact tracing of symptomatic index cases more efficient and efficacious than biweekly population testing (Kucharski et al). Requires speed (exposures alerted within 48 hours from index case developing symptoms) and scale (currently ~300k infections per day).
