New Orleans epidemics

I was in New Orleans at the end of the Covid-19 pandemic when I learned New Orleans is no stranger to epidemics. There have been yellow fever outbreaks in Louisiana since 1769. Between 1817 and 1905, over 41,000 people died of yellow fever in New Orleans, a swampy breeding ground of the mosquito that caused the fever. When things were bad, the pharmacy in the French Quarter would display red water in all their showglobes. It was a warning to be careful, there was fever about. The Pharmacy Museum, housed in the first licensed pharmacy in the U.S., had those red showglobes in their window in May 2021. Soon, I hope the color will change to something brighter and healthier.
