Which of the following diseases are transmitted from one person to another? 1. AIDS 2. Cirrhosis 3. Hepatitis B 4. Syphilis Select the correct answer using the code given below : Code :

Diseases transmitted from person to person are classified as communicable or infectious diseases. AIDS (HIV) is transmitted through the direct transfer of body fluids like blood, semen, and breast milk [2]. Hepatitis B is a viral liver infection spread via sexual contact, sharing contaminated needles, or perinatally from mother to child [5]. Syphilis is a bacterial infection primarily transmitted through sexual contact or vertically from mother to fetus [6]. In contrast, Cirrhosis is a chronic liver condition often resulting from long-term damage (such as alcohol abuse or chronic hepatitis) but is not itself a transmissible pathogen; it is a non-communicable physiological state [3]. Therefore, while the underlying causes of cirrhosis (like Hepatitis B) can be infectious, the disease 'cirrhosis' is not transmitted between individuals. Thus, only AIDS, Hepatitis B, and Syphilis are person-to-person transmissible diseases.
