Ongoing hepatitis A outbreak in Louisiana doubles in just two months
BY EMILY WOODRUFF | Staff writer Jul 23, 2019 - 2:44 pm

In a typical year, Louisiana sees about nine cases of hepatitis A, a liver infection that causes fatigue, jaundice, nausea and in rare instances death.

Louisiana is one of several states in the midst of a hepatitis A outbreak that shows no signs of slowing down, despite efforts to stamp it out.

Total Louisiana cases related to the outbreak, which started in January 2018, have more than doubled just in the past two months. In May, the number of 2019 cases related to the outbreak was 173. By June, the total number of reported cases jumped to 278, and it had reached 375 by July 18.

The outbreak is spreading mostly among drug users and homeless people, according to Dr. Frank Welch, the medical director for Louisiana?s Bureau of Community Preparedness. It's most concentrated in Livingston and East Baton Rouge parishes, which account for 160 to 200 of the cases...
