You can get it from: having vaginal, anal, or oral sex (using a condom or dental dam during sex can help prevent it) sharing toothbrushes and razors (blood on them can carry hepatitis B) sharing needles for shooting drugs, piercings, tattoos, etc. Because a high proportion of chronic HBV carriers were found to have HBV DNA in urine, it is suggested that irrespective of HBeAg/anti-HBe status, urine should be regarded as a potential route of transmission and therefore be investigated further as a means of horizontal and nosocomial transmission of HBV. It’s transmitted through contact with semen (cum), vaginal fluids, and blood. ![]() Detection of HBV DNA may indicate active viral replication, and thereby infectivity. A significant female predominance was also noted among the positive urine samples (P < 0.05), which was not correlated to the presence of haematuria. When comparing HBV DNA from serum and urine by an end-point titration PCR, a titration difference averaging 10(3) was found between serum and urine. The virus can be found in the bodily fluids of an infected person. Most HBeAg-positive patients had HBV DNA detectable in urine (91%), whereas urine samples from anti-HBe-positive patients were found to contain HBV DNA to a lesser extent (24%). Humans are the only known reservoir for the hepatitis B virus. HBV DNA was detected in serum from 46 patients (82%) and in urine from 28 patients (50%). Thirty-four of the patients were anti-hepatitis B e antigen (anti-HBe) positive and 22 were hepatitis B e antigen (HBeAg) positive. To investigate urine as a potential source of infection, serum and urine from 56 chronic hepatitis B surface antigen (HBsAg) carriers were examined for the presence of HBV DNA using the polymerase chain reaction (PCR). In most cases, the route of transmission is unknown. Transmission of HBV via tears, sweat, urine, stool, or droplet nuclei has not. Unless they are visibly contaminated with. chronic infections, including positive hepatitis B tests in pregnant women. Hepatitis B usually will go away by itself, but it may become chronic and. ![]() ![]() If you have any symptoms of hepatitis B, it’s important to check with a doctor or nurse for testing. Horizontal transmission of hepatitis B virus (HBV) without apparent sexual or parenteral exposure is common in hyperendemic areas. Feces, nasal secretions, sputum, sweat, tears, urine, and vomit have not been implicated in the spread of hepatitis B. dark-colored urine (pee) pale, clay-colored bowel movements (poop) jaundice when your eyes and skin get yellow.
