Silent spreaders may account for half of all cases of the novel coronavirus in the US, a new study suggests. If 17.9% of coronavirus cases have no symptoms, then presymptomatic cases account for 48% of transmission and asymptomatic accounts for 3.4%. Researchers determined that between 17.9 percent and 30.8 percent of all COVID-19 cases are asymptomatic. If the minimum 17.9 percent of cases are asymptomatic, they calculated that presymptomatic cases would be responsible for 48 percent of transmission and that asymptomatic would account for 3.4 percent. If the maximum 30.8 percent of cases are asymptomatic, they estimated 47 percent of transmission is from presymptomatic cases and 6.6. percent is from asymptomatic cases.
