How is shigella most commonly transmitted?

1. Through contaminated water

2. Person to person

3. Infected animals

4. Cooking mishaps

The correct answer is: Person to person

Shigella is primarily transmitted through direct person-to-person contact, particularly in environments where hygiene practices may be poor, such as daycare centers, nursing homes, and crowded living situations. The bacteria are shed in the stool of infected individuals, and even small amounts can cause infection. Unsanitary handwashing practices after using the restroom can contribute significantly to its spread. When an infected person does not thoroughly wash their hands after using the bathroom and subsequently touches surfaces, food, or other individuals, they can facilitate the transmission of the bacteria. While other modes of transmission can occur, such as through contaminated water, they are not as common for Shigella as person-to-person contact. Contaminated food and water are less frequent pathways for this specific pathogen compared to direct contact with an infected individual. Understanding the primary mode of transmission is crucial for implementing effective prevention measures, particularly in settings where the risk of outbreaks is higher.
