Which of the following is the reason for the most recent hepatitis A outbreaks?

The most significant recent outbreaks of hepatitis A have largely been attributed to person-to-person transmission. This type of transmission occurs when an infected individual comes into direct contact with another person, commonly through inadequate hand hygiene after using the restroom or consuming contaminated food.

While other factors, such as international travelers and food sources—both domestic and imported—can contribute to the spread of the virus, the prevalence and impact of person-to-person transmission have been notably higher in recent years. This highlights the importance of public health measures focused on sanitation and hygiene practices, especially in communities experiencing an outbreak.

Overall, understanding the dynamics of disease transmission underlines the significance of preventive measures, like vaccination and promoting proper hygiene, to reduce the incidence of hepatitis A.
