"It's very rare." To be sure, asymptomatic and presymptomatic spread of the virus appears to still be happening, Van Kerkhove said but remains rare. That finding has important implications for how to screen for the virus and limit its spread. "What we really want to be focused on is following the symptomatic cases," Van Kerkhove said. "If we actually followed all of the symptomatic cases, isolated those cases, followed the contacts and quarantined those contacts, we would drastically reduce" the outbreak.
