Study: Asymptomatic or pre-symptomatic cases primary driver of virus spreading

Local News

LAS VEGAS (KLAS) — A new study finds asymptomatic or pre-symptomatic people may be responsible for “half of all coronavirus cases” in the U.S.

The report, published by “The National Academy of Sciences” finds that more than one-third of these infections would need to be identified and isolated to prevent a future outbreak.

But researchers say even immediate isolation of all symptomatic cases would not be enough to get the spread under control.
