If the kitten scratched hepatitis C patients to the blood, and then I got to the blood, the percentage of infection?

Respond Tatyana Stepanova, a gastroenterologist, hepatologist percentage is difficult to say, nobody is investigated. If, however, between the receipt of the scratches it took several minutes, then the infection is possible. Similar question: Please tell me how many drops of blood needed for hepatitis C? Thank you in advance.
