My cousin had to cancel his bar mitzvah, which was planned for Saturday in Washington, DC.

Many other Americans are in similar situations during the outbreak of Covid-19, which has sickened more than 1,700 Americans and killed more than 40, according to an online tally being kept by Johns Hopkins University. Schools, religious institutions, and sports and concert venues have closed. Those who can work from home have been urged to do so. The White House reportedly overruled a proposal from the Centers for Disease Control that would have urged anyone over 60 to avoid airplane travel.
