The author witnessed cholera epidemics in Portugal that appeared suddenly in the years 1971, 1974, and 1975. Later, in Bissau, he dealt with an outbreak that erupted in 1987. This direct contact with the disease in different geographical contexts allowed him to acquire deep knowledge about the severity of cholera.
Due to this accumulated experience, the author is well acquainted with the control and prevention actions that must be applied when an outbreak occurs. The chronicles he publishes on the subject have a historical record character, seeking to document and preserve the memory of these occurrences.
The text is part of a series titled "On memories of cholera (I)," indicating that there are more chronicles on the same subject.
