What do we call the interval between exposure to infection and the appearance of the first symptom?

• A. Latency period
• B. Incubation
• C. Prodromal period
• D. Termination phase

Answer: (B)

The interval between exposure to infection and the appearance of the first symptom is referred to as the incubation period. During this time, the infectious agent is multiplying within the host, but symptoms are not yet evident. The length of the incubation period can vary widely depending on the type of infection and the individual host's immune response. The latency period typically refers to a state where an organism is present in the body without causing symptoms, but it's often used in different contexts, such as with certain viral infections or chronic conditions. The prodromal period describes the phase when early symptoms begin to appear, signaling the onset of illness, while the termination phase is not a commonly recognized term in the context of infectious disease progression. The correct term for the phase preceding symptom development is indeed the incubation period, highlighting its importance in understanding the timeline of infection and disease progression.
