HAV is transmitted through:
Correct answer: B. Oro-faecal route
- A. Blood transfusion
- B. Oro-faecal route
- C. Insect bites
- D. Sexual contact
Explanation
Hepatitis A is primarily transmitted through the faecal-oral route, which occurs when food or water contaminated with faeces from an infected person is consumed. This makes poor sanitation and hygiene key factors in its spread. Other routes, such as blood transfusion or insect bites, do not play a role in transmission. While sexual contact can occasionally contribute, it is not a major cause. Overall, maintaining proper hygiene and ensuring clean food and water are the most effective ways to prevent hepatitis A infection.
