What is the typical duration of the initial, non-specific phase of leptospirosis symptoms?

Answer

About three to seven days

The initial stage of leptospirosis, known as the anictric phase, is characterized by non-specific symptoms that typically persist for a defined period of three to seven days. During this time, patients experience general malaise, fever, and muscle aches, mimicking common flu-like illnesses, which complicates early diagnosis. If the disease resolves after this period, the infection clears without further issue; however, if it progresses, it enters the second, more severe phase following this initial week-long window.
