Mahjong does not usually cause infectious diseases when it comes into contact with wounds; however, if the mahjong is contaminated with live viruses that are easily transmitted through blood, such as Hepatitis B virus and HIV, you may contract an infectious disease.
The skin is one of the body’s main immune barriers, and when an injury to the skin results in an exposed wound, it may cause bleeding. At this time, if the mahjong is contaminated with the blood of a person with hepatitis B or HIV, and the blood contains viruses and the viruses are live viruses, it is possible to cause the transmission of viruses through the blood.
The probability of spreading the virus through mahjong contact wounds is still relatively small, but there must be a variety of conditions at the same time in order to cause the virus to spread. If the mahjong has been in contact with the virus and the virus survives on the surface of the mahjong, but usually the virus does not survive for too long after it leaves the body.
If the mahjong touches a wound, it is recommended that the wound be rinsed and disinfected in time to prevent bacterial and viral infections.
