Saliva swapping occurs when one person’s saliva is transferred to another, either directly through kissing or indirectly through objects. Saliva can carry viruses and bacteria, leading to the transmission of infections. Bacteria in the mouth can also be transferred through saliva, potentially causing serious problems. Diseases like mononucleosis and strep throat can be transmitted through saliva exchange, so precautions should be taken to avoid it.
Saliva swapping is a term used to describe any situation where one person’s saliva is transferred to another person. Sometimes this can be direct, through actions such as kissing, but it can also be indirect, with saliva passing from one person to an object and then to another person. An exchange of saliva is often the cause of the transmission of infections because saliva can carry viruses and bacteria.
In general, there are several ways in which an exchange of saliva can take place. The most common example that people generally think of is kissing, but there are others as well. For example, whenever people eat one after another, or if utensils are passed from one person to another, there is usually a small chance of saliva being exchanged. Indirect saliva exchange also occurs in some cases among children who may have a strong tendency to chew on their toys. People who carry this habit into adulthood and chew on pens or pencils may also inadvertently spread their saliva to others.
The human mouth can sometimes have a fair amount of bacteria present. This is partly due to moisture and partly because foods can occasionally get stuck in the teeth. Brushing and oral hygiene can potentially help in this regard, but are generally not considered foolproof. When saliva is exchanged, some of these bacteria can be transferred from one person to another, and in some cases, this can lead to serious problems.
Some of the microorganisms that live in the mouth can lead to important bacterial diseases and there are also some viral diseases that can be transmitted through saliva. In general, most things that can be passed on through mucus exchange, such as colds or the flu, can also be passed on through saliva. So in general, kissing or drinking after sick people can be as dangerous as being sneezed, and sometimes even more dangerous.
When it comes to infectious diseases transmitted through saliva exchange, the most classic example is probably mononucleosis, which has sometimes been called kissing disease due to this common method of transmission. Another fairly common and sometimes serious disease that is known to frequently pass through salivary exchange is strep throat. Overall, doctors generally suggest that people take some precautions to avoid exchanging saliva when a known contagion is present, usually including avoiding things like kissing and eating with the same utensils.
