Final answer:
True, an asymptomatic infection is one where the microbe is active in the host tissue but does not cause noticeable symptoms. Infected individuals can still spread the pathogen, often without being aware of their status.
Step-by-step explanation:
True: An infection that produces no noticeable symptoms even though the microbe is active in the host tissue is referred to as asymptomatic. Asymptomatic infections occur when an individual is infected by a pathogen but does not exhibit any symptoms, despite the pathogen being active within their body. This could be the case with various diseases, such as those caused by the herpes simplex virus, where most individuals with the virus remain asymptomatic and are generally unaware of their infection.
During an infection, pathogens like viruses and bacteria can multiply within the host's body. The infected individual, known as an active carrier, can transmit the pathogen to others, sometimes even before symptoms appear if they ever do. Understanding the dynamics of asymptomatic infections is crucial in controlling the spread of diseases, as these individuals can unknowingly contribute to the transmission of infectious diseases.
