Hepatitis C is a bloodborne disease. The current available research shows that 60% of those people that test positive can be traced to the known ways of coming in contact with infected blood.
There are several groups which are known to be at risk for contracting Hepatitis C:
Anyone who has had a blood transfusion or received blood products before 1993
Those who share needles for IV drug use
Health care workers who may come into contact with infected needles or blood
Policemen, Prison Guards, Firemen and Emergency Medical Teams exposed to infected blood
Anyone getting tattoos, or body piercing with infected needles
Sharing infected personal items that could harbor Hepatitis C blood, such as toothbrushes, razors, nail clippers etc.
Anyone who perform ritual acts that involve drinking human blood
Anyone who has had a blood transfusion in another country
Since there are still 40% of Hepatitis C patients who are uncertain how they contract the disease, caution should be used when living with a person who tests positive.
Never come in direct contact with an infected persons blood. Use caution during menstruation with a woman who tests positive for HCV.
Right now, there is a growing concern that we are unsure of all the ways of transmission. Therefore, always use caution.
