This year marks the 100th anniversary of the 1918 Spanish flu, the deadliest pandemic in human history. Over the course of the pandemic, an estimated one-third of the world’s population was infected, and anywhere from 20 to 100 million people were killed by the disease. Death rates were particularly high amongst otherwise healthy adults ages 20-40. In fact, the disease was so severe that the average life expectancy in the United States fell by almost 12 years.
Influenza hit the United States hardest in September, October and November 1918. In October alone, more than 100,000 Americans died from the flu and secondary infections, like pneumonia. Antivirals and antibiotics did not exist in 1918, so treatment was limited to home remedies and public health measures such as quarantines and closure of public venues like schools and churches.
The following is the chronicle entry from the Good Counsel Motherhouse in Mankato, Minnesota, which describes how the students at Good Counsel Academy were affected by the influenza epidemic.
 “On October 11th one of our day students brought the Spanish Influenza to Good Counsel. In a few days, 23 resident students were suffering therefrom. Onion and rye plasters saved them from death. Because of the dire contagion of this disease, school was closed for 15 days for the day students. The first victim in Mankato was a young Hospital Sister. Since it was a City Ordinance that every victim should be buried immediately, Sister was buried on a Sunday afternoon. The corpse could not be taken to the Church, but a delegation of our Sisters was present at the burial. Rev. Father Theis, S.J., gave a short funeral sermon. November 30th, Sister M. Regis, one of our Sisters teaching at the Cathedral School in Winona, fell a victim to the disease, and was buried immediately in the Parish Cemetery, R.I.P.”
