The correct answer and Explanation is :
The correct answer is B. Faeces.
Hepatitis A is a viral infection of the liver caused by the hepatitis A virus (HAV). It is primarily transmitted through the fecal-oral route. This means that the virus is shed in the feces of an infected person and can be ingested by another person through contaminated food, water, or surfaces. Understanding the reservoir of infection for hepatitis A is crucial for effective prevention and control measures.
Explanation:
- Fecal-Oral Transmission: The primary mode of transmission for hepatitis A is through the fecal-oral route. Individuals who are infected with HAV can shed the virus in their stool, which can contaminate food, water, or surfaces if proper sanitation practices are not followed. Ingestion of this contaminated material can lead to new infections.
- Prevention: Knowing that the reservoir for hepatitis A is fecal matter helps in implementing appropriate preventive measures. Proper hand hygiene, especially after using the toilet and before handling food, is critical in preventing the spread of hepatitis A. Ensuring safe drinking water and proper sanitation also plays a significant role in controlling outbreaks.
- Symptoms and Transmission: Hepatitis A often presents with symptoms such as jaundice, fatigue, abdominal pain, and gastrointestinal issues. It is highly contagious during the incubation period and the initial phase of the illness, when the virus is present in the feces but the individual may not yet exhibit symptoms.
- Public Health Measures: Vaccination against hepatitis A is an effective measure to prevent the infection. Additionally, public health education on hygiene practices and sanitation helps to reduce the risk of transmission. In outbreak settings, measures such as providing clean water and proper sewage disposal are critical in controlling the spread.
In summary, the fecal matter of an infected individual is the primary reservoir for hepatitis A, and understanding this helps in guiding preventive strategies and public health interventions to manage and prevent the spread of this virus.
