8 Diseases Transmitted By Saliva


Saliva is one of the most contagious bodily fluids there is since it is not necessary to come into direct contact with the mouth so that the saliva can transmit you an infection. A sneeze, sharing the same glass or saliva that can be splashed during a conversation is enough for someone else to be infected with certain conditions such as the flu or colds to even meningitis or mononucleosis. In this article, we are going to discover 8 diseases transmitted by saliva so that you can take them into account and prevent them.


One of the diseases transmitted by saliva is mononucleosis or also known as “kissing disease”. It is a condition that appears due to the Epstein – Barr virus that is spread by salivary; among its most prominent symptoms we highlight the typical signs of influenza but aggravated, that is, high fevers, severe headaches, fatigue and, even, skin rashes may appear.

The contagion of this condition can occur by direct contact with saliva(through kissing) but, also, by indirect contact, that is, by coughing or sneezing that can send this virus through the saliva and infect it to the other person which is close to the patient.

The way to treat mononucleosis is to alleviate the symptoms because, to date, there is no medication that can combat this virus. Anti-inflammatories such as ibuprofen or paracetamol are prescribed to fight some signs such as a headache, malaise, fever, and so on. To be able to fight the disease it is important to maintain absolute rest.

Herpes labialis

Another disease that is transmitted by saliva is cold sores that, in addition, once it is infected by someone’s organism, the virus remains dormant and can reappear at other times, such as during periods of stress, falls from defenses, moments of anxiety, etcetera.

This herpes can be spread by kissing, but also by saliva if it reaches the virus. Therefore, it is important to avoid kissing someone you see with small herpes because it is quite likely that you end up being infected. It is also recommended that you avoid touching it with your hands and, if you have done so, wash it off so that another area of your body can get the virus. In a How we tell you in detail how you get a mouth herpes so you know all the routes of infection that exist and, well, you can avoid it.

Cold sores usually disappear between 1 and 2 weeks but if you want to accelerate the healing you can use antiviral creams that are specially designed to eradicate herpes that appear in this part of the body. This cream usually relieves pain as well as accelerating its cure and, in addition, you can buy it at the pharmacy without a prescription. There are also creams of vitamin E, a nutrient that will help you accelerate the cure by hydrating the area and reducing burning and itching.

Hepatitis A

It is a viral disease highly contagious and that directly affects the liver producing an inflammation of it and preventing it from performing its natural function of eliminating waste. The most common way for the hepatitis A virus to spread is through water or some foods that have this infection, but it can also be transmitted through sexual, salivary or blood. This type of hepatitis is one of the mildest that exist and, with a specific treatment, the patient usually overcomes the disease without too many complications.

The symptoms that this condition can produce are very similar to those of common flu but in a more intense and lasting way, in addition, it can also affect the color of urine, skin, and eyes that tend to be more yellowish. The duration of this condition usually lasts between 2 to 6 weeks during which the patient must rest and follow the doctor’s instructions.

Bacterial meningitis

Meningitis is another disease transmitted by saliva still kissing, sneezing or coughing most frequent methods of infection. This disease affects the meninges, that is, the membranes that surround our brain and spinal cord and that, when inflamed, can cause intense headaches, dizziness, and generalized discomfort.

This condition can be bacterial or fungal, that is, the agent causing it is a virus or a fungus; of which we speak in this section is of the bacterial one because it is the one that is transmitted by the saliva. The treatment of the same goes directed to eliminate the microorganism of our nervous system and, also, reduce the symptoms and the neurological complications that can appear.

It will always be a specialist who has to tell you the best treatment to follow in order to combat the disease permanently.


Also through the saliva, the parotiditis can be infected or more known as “mumps“. This condition occurs when the parotid (salivary) glands become inflamed due to the paramyxovirus virus, they usually appear during childhood, although they can also be present at any other age.

It is a viral disease that can cause severe pain in the patient, in addition to producing inflammation of the upper neck affecting the voice, breathing and swallowing food and drinks. There is no specific treatment for this situation and, to pass this drink, the doctor will prescribe medicines designed to reduce the symptoms and hope that the virus disappears by natural way.

Oral candidiasis

Thrush is a fungal infection that occurs when Candida albicans grows excessively in the mouth cavity beginning on the tongue, through the palate, send, tonsils and throat. The reason why this condition appears is that our defenses are weakened and, therefore, these microorganisms can multiply producing the typical symptoms of this condition.

It can be spread to another person through the salivary tracts either through direct contact (kissing) or indirectly (coughing, sneezing, etc). It is important to see a doctor when you begin to experience the first symptoms to be prescribed antifungal medications that can remit this fungus permanently.

In the same way, it is important that during these days extremes to the maximum oral hygiene to prevent the fungus to continue to expand in the area. Some of the measures that you will have to follow are the following:

Another of the diseases transmitted by saliva is chickenpox, a highly infectious disease that occurs due to the varicella-zoster virus and that produces the appearance of skin rashes that usually contain a yellow liquid inside. It is a very annoying condition because it produces strong itching and these formations can appear in any area of the human body.

The most frequent signs that accompany this disease are fever, fatigue, malaise, and so on. It is common to suffer chickenpox during childhood because it is very contagious and just with a child in the class having it, they increase the chances that others will also fall ill; However, it can also be the case that an adult suffers it, producing much more complicated consequences.

This disease is usually contagious when skin rashes are touched directly, but it can also be caused by salivary contact or secretions when sneezing, talking, coughing, and so on. If an infected person has used some concrete utensils and another healthy person uses them, there is also a risk of suffering from this disease.

Flu and colds

And, obviously, within this list could not miss two of the most common diseases that can be spread by saliva: influenza and colds. Both conditions tend to occur in a generalized way during the cold months because our system of defenses is more weakened, so the flu virus can travel through the droplets of saliva and affect different people who can receive them (in the metro, in work, in class, etc.). The same goes for colds that can be passed on to each other due to sneezing, coughing or sharing personal items (glasses, cutlery, etc.).

The flu produces symptoms that are stronger in intensity than the common cold, but in general, the two conditions produce headache, mucus, sore throat, fever, tiredness, bone pain, and so on. It is important to rest so that our body can fight with infectious agents, you can also take some medications to combat these symptoms and to feel better.
