Which type of disease is infectious and transmissible from one individual to another?

• A. Noncommunicable Diseases
• B. Communicable Diseases
• C. Chronic Diseases
• D. Acute Diseases

Answer: (B)

Infectiousness and the ability to spread between people define a communicable disease. When a disease-producing agent, like a virus or bacterium, can pass from one person to another, we call it communicable. Noncommunicable diseases are not spread through infection between people. Chronic diseases describe long-lasting conditions and are typically not infectious. Acute describes how quickly an illness develops or its duration, not whether it is transmissible; some acute infections are communicable, but the defining feature here is the capacity for person-to-person transmission. So, the disease type that is infectious and transmissible from one individual to another is communicable.
