A disease in which a pathogen remains inactive for a long period of time before becoming active is termed a(n) __________ .


a. subacute disease
b. acute disease
c. chronic disease
d. latent disease

Verified step by step guidance

1. Understand the definitions of each type of disease listed in the options.
2. A subacute disease is characterized by symptoms that are less severe than acute diseases and last longer than acute diseases but not as long as chronic diseases.
3. An acute disease is one that develops rapidly but lasts only a short time, often with intense symptoms.
4. A chronic disease is one that develops slowly and lasts for a long time, often for the rest of the person's life.
5. A latent disease is one where the pathogen remains inactive for a period of time before becoming active, causing symptoms.

Key Concepts

Latent Infection

A latent infection occurs when a pathogen remains dormant within the host for an extended period, showing no symptoms. This state can be triggered by various factors, such as stress or a weakened immune system, leading to the reactivation of the disease. An example is the varicella-zoster virus, which causes chickenpox and can later reactivate as shingles.

Acute Disease

An acute disease is characterized by a rapid onset of symptoms and a short duration. These diseases often require immediate medical attention and can be severe but typically resolve quickly with appropriate treatment. Examples include influenza and strep throat, which manifest suddenly and are often self-limiting.

Chronic Disease

Chronic diseases are long-lasting conditions that can be controlled but not cured. They often develop slowly and may persist for months or years, leading to ongoing health issues. Examples include diabetes and hypertension, which require continuous management and can significantly impact a person's quality of life.
