Definition

Typhus fever (noun): 1. A severe infectious disease caused by rickettsia bacteria, transmitted primarily by the bite of infected body lice, and characterized by high fever, severe headache, and a distinctive skin rash.

Usage

• Typhus fever is a specific medical term for the disease. It is often used in historical, medical, or epidemiological contexts.
• The term is typically used as a non-count noun to refer to the disease in general.
• Example: "The overcrowded prison camp was a breeding ground for typhus fever."

Examples

• "During the war, many soldiers died not from wounds but from typhus fever."
• "The doctor suspected typhus fever after observing the patient's rash and high fever."
• "Outbreaks of typhus fever are now rare in areas with good sanitation and hygiene."

Advanced Usage
