If the illness is infectious then you cannot use the binomial distribution because the incidences of illness are no longer independent events, so that the assumptions required for the binomial distribution are not satisfied.
Suppose the illness is not infectious and the "normal" rate of illnesses is p. Then in a group of size n, the number of units suffering has a B(n, p) distribution. You can then determine a critical region at an appropriate level of significance and test the number of victims against that.

The war ended in 1918. That coincided with the outbreak of Spanish Influenza. The outbreak turned into an epidemic. The death toll of both soldiers and civilians increased drastically because of the disease.
There was no cure for the sweating sickness, but there were survivors. Since the virus disappeared after the 1551 outbreak, it is an illness that hasn't been largely studied. It is theorized that the sweating sickness caused massive dehydration and that was what led to death. If the victim was healthy and hydrated when the illness hit, the likelihood of survival was greater. Anne Boleyn was among the survivors in the outbreak in 1528 where thousands died in a matter of a few weeks.
Food-Borne disease is a disease that is carried by eating food. Legonaires disease is an example of large numbers of people becoming very ill or even dying from all eating at the same place, and eating the same foods. Dirty restaurants are one of the immediate causes that comes from a source. Other sources could be from infected animals.

No epidemic has a "day" that it started and I believe you have the wrong year listed in your question. The major U.S. yellow fever epidemic occurred in 1793 and the first probable outbreak of the disease was in 1648 in Yucutan, where the illness was termed xekik (black vomit). At least 25 major outbreaks followed, such as in Philadelphia 1793, where several thousand people died and the American administration as well as George Washington had to flee the city. Yellow fever epidemics in North America caused some 100,000-150,000 deaths. Major outbreaks also occurred in Europe, e.g. in 1821 in Barcelona with several thousand victims. In 1878, about 20,000 people died in an epidemic in the Mississippi River Valley and the last major outbreak in the US occurred in 1905 in New Orleans.

Yes, there is a statistical correlation that if someone in a family is diagnosed with a mental illness the probability is higher that others in the family will also have mental disorders (relative to a family with no known individuals with diagnosed mental illness). The cause of this correlation is unknown, but is believed to have both genetic and environmental contributions.
Another word to describe epidemic is outbreak. For example, when the measles is diagnosed in a school, the epidemic can be widespread or an outbreak can occur among students and teachers.
