The press (books, newspapers, magazines, calendars, etc) in the Lithuanian language educated its readers extensively on the prevention and treatment of infectious diseases in the early 20th century. However, the frequent outbreaks of various epidemics from the 1900s to the 1930s raises the question whether this information really reached its target audience, especially when, as folklore sources show, folk medicine was still heavily relied on in the provinces. The article addresses this question by taking cholera as an example. It compares the methods of protection against cholera and its treatment, as presented in Lithuanian periodicals and professional publications, with narratives of folk medicine collected in archives. In the collected material, the author looks for definitions of the folk concept of communicable diseases (limpamos ligos, the name given to infectious diseases at the time), which may have influenced the limits to which people followed the recommendations of medics in the first half of the 20th century.
