Prevention of HAV in children involves several strategies: - Vaccination: The hepatitis A vaccine is highly effective in preventing HAV infection. It is recommended for all children starting at age 1. - Hand hygiene: Encouraging frequent handwashing with soap and water, especially before eating and after using the restroom, can help prevent the spread of HAV. - Safe food and water: Ensuring that children consume clean, safe food and water can reduce the risk of infection. This is particularly important when traveling to areas where HAV is common. - Avoiding contact with infected individuals: Teaching children to avoid close contact with anyone who has HAV can help limit transmission.
