Slide 2 (Person)

The reported Hepatitis A cases by sex in the United States from 2004 to 2019 are displayed on this slide. This slide emphasizes the descriptive epidemiology’s person element. The Hepatitis A infection rate is represented on the Y-axis in hundred of thousands of cases. The X-axis shows the years between 2004-2019. The data by sex show that males have more cases of Hepatitis A infection than females. The graph shows a steady decrease of reported cases between 2004-2011 among all sexes and then steady rise of the reported cases from 2014-2019 among both sexes. Since the initial person-to-person infections were documented in 2016, there has been a spike in the reported incidence of hepatitis A among both sexes.

The areas with the most cases are characterized by a deep blue color while the areas with the least cases are characterized by a light blue color.

Slide 4 (Time)

The slide shows the time course for the acute Hepatitis A reported cases and acute Hepatitis A Estimated cases by year between 2015-2019 in the US. The number of cases is depicted on the Y-axis.

Incidence of hepatitis A increased by 1,325% from 2015 to 2019. The spike in 2019 was brought on by the un-precedented person-to-person outbreaks in 31 states, mostly among drug users and homeless people.
