Poor sanitation conditions may NOT be the likely reason behind which of the following diseases/conditions?

Arthritis

The correct answer is Option (3)- Arthritis

Poor sanitation conditions are not likely to be the reason behind arthritis.

Arthritis is a condition characterized by inflammation of the joints, which can be caused by various factors such as genetics, autoimmune disorders, infections, and wear and tear on the joints over time. Poor sanitation conditions primarily contribute to the spread of diseases caused by contaminated water or food, such as typhoid and cholera, which are typically transmitted through the ingestion of water or food contaminated with fecal matter containing the causative pathogens (Salmonella typhi for typhoid and Vibrio cholerae for cholera). Polio, another disease listed, is caused by the poliovirus and can also be transmitted through contaminated water or food. However, arthritis is not directly linked to poor sanitation conditions and has different causes unrelated to sanitation.
