Understanding Hepatitis -- Prevention

Many types of hepatitis can be prevented by making informed lifestyle choices. Vaccinations are available for hepatitis A and B. Adequate sanitation and clean personal habits will help reduce the spread of hepatitis A and hepatitis E. In areas where sanitation is questionable, boil water. Cook all food well and peel all fruit.

The most common way to get hepatitis C is by sharing needles and other equipment (such as cotton, spoons, and water) used to inject illegal drugs. If you are injecting drugs, the best way to protect yourself is by not sharing needles or other equipment with others. Many cities have needle exchange programs that provide free, sterile needles so that you do not have to share needles. If you want to stop using drugs, ask your doctor or someone you trust to help you get into a drug treatment program.

Before 1992, people could get hepatitis C through blood transfusions and organ transplants. Since 1992, all donated blood and organs are screened for hepatitis C, so it is now rare to get the virus this way.

In rare cases, a mother with hepatitis C spreads the virus to her baby at birth, or a health care worker is accidentally exposed to blood that is infected with hepatitis C.

Experts are not sure whether you can get hepatitis C through sexual contact. If there is a risk of getting the virus through sexual contact, it is very small. Your risk is especially low if you are in a long-term, monogamous relationship.

If you live with someone who has hepatitis C or you know someone with hepatitis C, you generally do not need to worry about getting the disease. You can help protect yourself by not sharing anything that may have blood on it, such as razors, toothbrushes, and nail clippers.

Contagious and incubation periods

The incubation period is the time it takes for symptoms to appear after the hepatitis C virus has entered your body, and it is any time from 2 weeks to 6 months.

Anyone who has hepatitis C can spread the virus to someone else. If testing shows you have hepatitis C, do not share needles. And keep cuts, scrapes, and blisters covered.
