Hepatitis C Virus Infection, United States
New infections per year 1985-89 242,000
2001 25,000
Deaths from acute liver failure Rare
Persons ever infected (1.8%) 3.9 million (3.1-4.8)*
Persons with chronic infection 2.7 million (2.4-3.0)*
HCV-related chronic liver disease 40% - 60%
Deaths from chronic disease/year 8,000-10,000
*95% Confidence Interval

Estimated Incidence of Acute HCV Infection
United States, 1960-2001

Prevalence of HCV Infection by
Age and Gender, United States, 1988-1994

Exposures Known to Be Associated With
HCV Infection in the United States
Injecting drug use
Transfusion, transplant from infected donor
Occupational exposure to blood
Mostly needle sticks
Iatrogenic (unsafe injections)
Birth to HCV-infected mother
Sex with infected partner
Multiple sex partners

Reported Cases of Acute Hepatitis C by
Selected Risk Factors, United States,
1982-2001*

Sources of Infection for
Persons With Hepatitis C

Reduce or Eliminate Risks for
Acquiring HCV Infection
Screen and test donors
Virus inactivation of plasma-derived products
Risk-reduction counseling and services
Obtain history of high-risk drug and sex behaviors
Provide information on minimizing risky behavior, including referral to other services
Vaccinate against hepatitis A and/or hepatitis B
Safe injection and infection control practices

HCV Prevalence by Selected Groups
United States

HCV Testing Routinely Recommended
Ever injected illegal drugs
Received clotting factors made before 1987
Received blood/organs before July 1992
Ever on chronic hemodialysis
Evidence of liver disease
Healthcare, emergency, public safety workers after needle stick/mucosal exposures to HCV-positive blood
Children born to HCV-positive women

Postexposure Management for HCV
IG, antivirals not recommended for prophylaxis
Follow-up after needlesticks, sharps, or mucosal exposures to HCV-positive blood
Test source for anti-HCV
Test worker if source anti-HCV positive
Anti-HCV and ALT at baseline and 4-6 months later
For earlier diagnosis, HCV RNA at 4-6 weeks
Confirm all anti-HCV results with RIBA
Refer infected worker to specialist for medical evaluation and management

HCV Counseling
Prevent transmission to others
Direct exposure to blood
Perinatal exposure
Sexual exposure
Refer to support group

Preventing HCV Transmission to Others
Do not donate blood, body organs, other tissue or semen
Do not share items that might have blood on them
personal care (e.g., razor, toothbrush)
home therapy (e.g., needles)
Cover cuts and sores on the skin

Persons Using Illegal Drugs
Provide risk reduction counseling, education
Stop using and injecting
Refer to substance abuse treatment program
If continuing to inject
Never reuse or share syringes, needles, or drug preparation equipment
Vaccinate against hepatitis B and hepatitis A
Refer to community-based risk reduction programs

Mother-to-Infant Transmission of HCV
Postexposure prophylaxis not available
No need to avoid pregnancy or breastfeeding
Consider bottle feeding if nipples cracked/bleeding
No need to determine mode of delivery based on HCV infection status
Test infants born to HCV-positive women
>15-18 months old
Consider testing any children born since woman became infected
Evaluate infected children for CLD

Sexual Transmission of HCV
Do not need to change their sexual practices
Should discuss with their partner
Risk (low but not absent) of sexual transmission
Counseling and testing of partner should be individualized
May provide couple with reassurance
Some couples might decide to use barrier precautions to lower limited risk further

Sexual Transmission of HCV
At risk for sexually transmitted diseases, e.g., HIV, HBV, gonorrhea, chlamydia, etc.
Reduce risk
Limit number of partners
Use latex condoms
Get vaccinated against hepatitis B
MSMs also get vaccinated against hepatitis A

Other Transmission Issues
HCV not spread by kissing, hugging, sneezing, coughing, food or water, sharing eating utensils or drinking glasses, or casual contact
Do not exclude from work, school, play, child-care or other settings based on HCV infection status
