Blood Test On Hepatitis B
One of the most contagious and most insidious of all the STDs, the hepatitis B virus can cause a debilitating liver disease that has no known cure or effective treatment. It is spread like the virus causes AIDS - through blood contact with body fluids that contain it - but is considered to be about 100 times as contagious because it may even be spread by contaminated acupuncture needles, dental equipment, and even manicuring tools, as well as by saliva exchanged in kissing. It is difficult to estimates the number of people who carry the infection because half of them may develop no symptoms. Of these, many remain contagious for a lifetime, spreading liver disease that makes its victims 200 times more likely to develop liver cancer than their non-infected counterparts. While there has been a decline in cases among homosexual men because of a change in there sexual habits, there has been a considerable increase among sexually active heterosexuals with many partners.
