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 |

Hepatitis C by
Selected Risk Factors, United States,

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 |
