Hello: The transmission routes for Hepatitis B and C are through the entry of virus-containing blood or bodily fluids (including semen and saliva) into broken skin or mucous membranes.
If the viral load in saliva is high (which is generally low), there is still a chance of infection.
Wishing you good health!

More Info

Hepatitis B and C are viral infections that primarily affect the liver and are transmitted through specific routes. Understanding the transmission methods is crucial in addressing concerns about potential infection through contaminated sources, such as saliva in mineral water.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are primarily transmitted through blood-to-blood contact. This includes sharing needles, receiving contaminated blood products, and, in some cases, sexual contact. For HBV, transmission can also occur from mother to child during childbirth. However, the risk of transmission through saliva is significantly lower compared to blood.

When it comes to saliva, studies have shown that while HBV can be present in saliva, the concentration is much lower than in blood. The primary concern with saliva transmission would be if there were open sores or bleeding gums, which could theoretically allow for blood to mix with saliva. However, the likelihood of contracting hepatitis B or C from drinking mineral water that has been contaminated with the saliva of an infected person is extremely low. The virus does not survive well outside the human body, and the dilution factor in water further reduces any potential risk.

For hepatitis C, the risk of transmission through saliva is even lower. HCV is not typically found in saliva in significant amounts, and there are no documented cases of transmission through saliva alone. The primary transmission routes remain blood-to-blood contact.

In summary, drinking mineral water that may contain saliva from a person infected with hepatitis B or C poses a negligible risk of transmission. The viruses require specific conditions for transmission, and casual contact through saliva in this manner does not meet those conditions.
It is important to maintain good hygiene practices and avoid sharing personal items that may come into contact with blood, such as razors or toothbrushes. If you have concerns about potential exposure to hepatitis B or C, it is advisable to consult with a healthcare professional for appropriate testing and guidance. Regular screening and vaccination (for hepatitis B) are effective measures to prevent these infections.
In conclusion, while it is always wise to be cautious about potential exposure to infectious diseases, the risk of contracting hepatitis B or C from saliva in mineral water is extremely low. Understanding the transmission routes and maintaining good health practices are key to preventing these viral infections.
