    Rural retreats have been popular since at least the first century bc, when wealthy ancient Romans waited out the annual malaria season in country villas.

  • A bouquet of herbs


    Although historians have disputed the theory that the nursery rhyme “Ring Around the Rosie” originated during the 1665 Great Plague of London, posies—bouquets of herbs or flowers—were believed at the time to have medicinal value.

    While U.S. clothing sales declined overall in spring 2020, online searches for sweats jumped 50 percent.

    In early modern Europe, Christian and Jewish communities alike made paper amulets invoking divine protection against plague, which they hung in their homes or carried on their persons.
