Final answer:
Hepatitis A is primarily transmitted through fecal contamination of food or water and can be prevented with proper hygiene, sanitation, and vaccination.
Step-by-step explanation:
The hepatitis A virus (HAV) is transmitted primarily through fecal contamination of food or water. Family members of a patient with hepatitis A are at risk of infection if they consume food or water that has been contaminated with the feces of the infected person. Proper hygiene and sanitation practices, including handwashing and ensuring clean water and food sources, are essential in preventing the spread of HAV.
Furthermore, hepatitis A is a self-limiting virus, which means it often resolves on its own without leading to chronic disease. It is also preventable through vaccination, which is particularly recommended for children and certain high-risk groups. Considering these factors can help mitigate the risks of HAV transmission among family members and the general population.
