The fatality rate is unknown since it appears that most people exposed to the disease don’t get sick enough to tell those who keep statistics. Unlike flu, it doesn’t have a severe impact on children, and Baruch ha-Shem, our community has lots of children. It is an extra round of flu season, with no vaccine.
It is not, unless it mutates, anything all that serious (compare the regular measles, chicken pox and polio epidemics prior to the vaccine, the influenza of 1918, and the plague epidemics prior to antibiotics). The world really isn’t ending.
