A spurt early last year in heroin-related hepatitis C cases among Hastings youths appears to have tapered off by year's end, state health officials say.
And countywide, heroin arrests dropped last year after peaking during 2009, according to the Dakota County Drug Task Force.
Heroin use had been growing in the county and statewide over the past five years, and last summer the state Department of Health issued advisories to local health providers after it received reports in June that Hastings young people accounted for nine of 16 cases of hepatitis C identified in Dakota County.
A number of those infected, ages 16 to 27, admitted to sharing heroin needles, said Doug Schultz, a Health Department spokesman. If untreated, the virus can lead to liver disease and other complications.
At the Star Tribune's request, the department provided a year-end update that showed that in the last six months, only two more hepatitis C cases were reported for the 30-and-under age group in Dakota County, and neither case was in Hastings, Schultz said.
Still, the total of 18 hepatitis C cases in 2010 was a jump from eight in 2009, noted Kristin Sweet, a department epidemiologist.
"Going from eight to 18 is dramatic enough for us to notice and look into it," Sweet said. She said not all heroin users are tested for hepatitis C, so the number of users is likely higher.
"It appears the outbreak is over, but we can't say for sure," Sweet said. After the June reports of a jump in youth with the virus, the department watched the 30-and-under age group all year, she said.
