The huge problem is the number of asymptomatic people who have the virus. On the cruise ships that have provided the best look at the spread and effects on people who have it there were more than 20% with the virus that had no symptoms. Since it’s about 3 times as contagious as the flu viruses having asymptomatic carriers is a huge problem. The immediate lockdown was the best that could be done but it’s unlikely that the virus is contained to two or three individuals. I hope it is. Be safe .
