LITTLE ROCK (KATV) —
Since February, Arkansas has recorded the most Hepatitis A cases the state has seen likely since the virus's vaccine was approved in the United State back in the mid 1990s. The elevated number of Hep A cases, part of a nationwide outbreak predominantly affecting northeast Arkansas - but public health officials say Hepatitis C infections far outweigh the number of people with Hepatitis A in the Natural State.
"In a normal year we'll see three to five cases of Hepatitis [A]," said Dr. Dirk Haselow, Ph.D. state epidemiologist for the Arkansas Department of Health.
As of November, more than 200 cases of Hepatitis A have been reported in Arkansas; a large majority of those cases have been concentrated in Greene, Clay, Craighead and Lawrence counties.
While the spread of Hep A had previously been associated with improper hand-washing and transmission of fecal matter, research has found an increase cases tied to injection drug use in addition to other risk factors like chronic homelessness, men who have sex with other men and incarcerated populations.
"We have people with these risk factors throughout the state," said Haselow. "The fact that it hasn't spread from there is to some extent good fortune, and we are trying our hardest to contain it where it is."
Hepatitis A vaccinations have been required for children in Arkansas since 2013 and had been suggested by the American Association of Pediatrics for about a decade prior. It's why the Hep A outbreak in Arkansas is mostly affecting people between the ages of 20-65.
Tackling the Hep A outbreak has been difficult for the state, primarily due to the infection's incubation period.
"It's typically between three weeks and three months," said Haselow. "I don't remember what I ate yesterday - most people don't. And to think that you would have a precise memory going back three weeks or three months of what you might have been exposed to makes it really difficult to track down people like this."
In the state's response to the Hepatitis A outbreak and subsequent screening, tests have shown that roughly one-third of those testing positive for Hepatitis A are also testing positive for Hepatitis C.
"Hepatitis C has been described by Newsweek and Time Magazine as the hidden epidemic," said Haselow. "Roughly two-percent of Americans have Hepatitis C and many not know it. So in Arkansas, you know two-percent of three-million people is quite a few - 60,000 people."
Part of the reason Hepatitis C is likely more widespread across Arkansas than Hepatitis A is the self-limiting nature of Hep A, as well as the availability of vaccines.
"You end up with a diarrheal illness and it goes away," said Dr. Ryan Dare, an infectious diseases doctor and professor at UAMS.
The Hepatitis A outbreak has required roughly half of Arkansans infected to be hospitalized, according to Haselow, the disease will likely only last a month, with symptoms and the disease clearing the patient's system. On the flip side, Hepatitis C typically lays dormant until it isn't and can result in liver disease and liver failure if left untreated.
"You live with it for life, unless we provide treatment to get ride of it," said Dare.
What the state agencies are doing to help combat the outbreak of Hepatitis A and get a better grip on the spread of Hepatitis C in Arkansas, plus how and why its being spread - the full story Monday at 10:00 PM on KATV Channel 7.
