What is the term for the condition where an individual currently shows symptoms of a disease?

The term that accurately describes the condition where an individual currently shows symptoms of a disease is "ill of infection." This phrase refers to the state of being affected by an infectious disease, where the individual presents identifiable symptoms such as fever, cough, or fatigue that indicate an active infection.

The other terms relate to different stages or states in the context of infectious diseases. A chronic infection refers to a long-lasting infection that may not exhibit symptoms all the time but can persist for extended periods. The incubation period refers to the time between exposure to the pathogen and the onset of symptoms, during which the individual may not yet show signs of illness. Asymptomatic refers to individuals who are infected with a pathogen but do not exhibit any symptoms, meaning they do not show signs of being ill despite carrying the infection.

In summary, "ill of infection" is the term that correctly describes someone who is currently symptomatic and demonstrates observable signs of a disease.
