From Eurosurveillance Monthly Release Volume 11/Issue 1 January 2006
 

"In 1982, an American physician notified the Municipal Health Service (MHS) in Amsterdam that eight American soldiers had contracted hepatitis B during their stay in Amsterdam.  All these soldiers had visited the same tattoo studio. A public health nurse from the MHS department of infectious diseases made a site visit where he noticed that the tattooist used extremely unhygienic procedures. He had a bucket filled with bloody water and a sponge, which were used to 'clean' the skin where the tattoo was to be applied. He used the same needles on all clients, without any cleaning in between. To test whether the needles were still sharp, he touched them on the back of his hand before he started tattooing clients.
In the same year, a survey carried out among all tattoo studios in Amsterdam indicated that hygienic conditions were universally bad. This finding, together with the hepatitis B outbreak, supplied the impetus to urgently set up local regulations for the tattoo studios, working with one of the tattooists."

Yes, No Effect, No 

8) After the tattooist tested the needles for sharpness on himself is it likely the needles were contaminated with the tattooist's blood?

9) If the Tattooist Did NOT have Hepatitis, and he tested the needles each time on himself,
then would this decrease the likelihood of the soldiers getting hepatitis at his shop. Yes or No
