CLEARFIELD -- With chlamydia at the top of the list, sexually transmitted diseases continue to push the reported number of communicable diseases upward in Davis County.
That was the news shared with the Davis County Board of Health, ironically on Valentine's Day.
In 2011, the health department received 1,369 disease reports, up 9 percent from the 2010 report of 1,256 cases, said Brian Hatch, director of the county health department's communicable disease and epidemiology division.
"This year, another busy year," Hatch said in presenting the annual report to the board.
Of the 1,369 reports received, Hatch said, 772 were sexually transmitted diseases, with 739 being chlamydia cases. The number of 2011 chlamydia cases is 37 more than in 2010.
"You guys hear it every year," Hatch said of the increase in chlamydia cases.
"What is alarming," Hatch said of the county's STD rate, "is that we are catching up to the state rate in Davis County."
For the county to reduce the number of chlamydia cases, it needs to implement better education measures targeting the age group -- 15 to 28 years old -- who studies show are at the greatest risk of being affected by the disease, Hatch said.
After chlamydia, the highest number of reported disease incidents in the county involved hepatitis C, acute and chronic, with 150 cases reported, he said.
The number of reported hepatitis C cases in the county was more than double the 71 cases reported in 2010, Hatch said.
Hepatitis C is caused by a virus that infects the liver. HCV is a blood-borne pathogen predominantly spread by exposure to contaminated blood or blood products.
Tuberculosis was the third-highest disease total, with 66 cases reported.
In 2011, a measles outbreak resulted in 15 confirmed cases statewide and 16 "suspected cases" in Davis County.
Despite not having a single confirmed case of measles, Hatch said, the county health department spent $20,000 to address and respond to the suspected cases.
Also reported to the county was one case of salmonellosis, which was linked to a national cluster, and 17 cases of norovirus, affecting the stomach and intestines.
The norovirus outbreak was linked to a basketball camp held outside of Davis County. Of the 39 Davis County teens attending the camp, 17 contracted the virus, Hatch said.
Seven cases of E. coli were linked to a Scout camp that several Davis residents attended in Idaho.
The source of the outbreak was contaminated water, Hatch said.
