What are the Infectious Diseases that Spread through Saliva

timesofummah.com – What are the Infectious Diseases that Spread through Saliva. The mouth is home to hundreds of different microorganisms. Saliva or saliva can function as an important defense for the body because it has antibodies and enzymes that reduce the risk of disease transmission. However, saliva can also transmit certain diseases. COVID-19 is one example.

Here are some infections that can be spread through saliva and kissing. Listen to the end, OK!

1. Diseases transmitted through saliva

Infectious diseases can spread through several routes of transmission. Oral transmission refers to the spread of microbes through saliva or sharing food and drink.

When you accidentally ingest something contaminated with microbes, such as saliva during a kiss, the act of swallowing your tongue washes away the microbes at the back of your throat, allowing them to enter your body.

Infections, such as mononucleosis caused by Epstein-Barr virus (EBV), and cytomegalovirus (CMV), are examples of infections spread by oral transmission of virus-containing saliva.

Other infectious microbes that are spread through saliva do so by attaching to the inside surfaces of the cheeks and mouth, tongue, or teeth. An example is the Streptococcus bacteria, which can cause a variety of infections, including gum disease and strep throat, citing the Merck Manual.

According to Kaiser Permanente, the surfaces of the respiratory tract (nose, mouth and throat) are continuous and composed of similar tissues. Microbes found in saliva can generally be found in other parts of the respiratory tract, including the nose and throat. Therefore, even colds and flu (and other respiratory infections) can be spread through saliva.

2. Infectious diseases from sores in the mouth

Certain infections that cause ulcerations or sores in the mouth can also be spread through kissing. These include cold sores (small blisters that develop on the lips or around the mouth) and hand, foot, and mouth disease.

Cold sores are caused by the herpes virus, usually the herpes simplex virus 1 (HSV-1). Although related, it is different from herpes simplex virus 2 (HSV-2), which is more commonly associated with genital herpes.

Unlike an infection that is spread through saliva, HSV-1 is spread through an open cold sore on the lips or near the mouth. Although the infection is contagious through all stages of a cold sore, it is most contagious when the wound is open and there is discharge.

Hand, foot and mouth disease caused by the coxsackievirus is another infectious disease that is spread through open sores in the mouth. This is a type of enterovirus, which is a common infection that has many of the types we often encounter. This particular infection is common in children, especially in daycare or preschool.

Hand, foot and mouth disease is spread by inhaling air after a sick person coughs or sneezes, touching or close contact such as kissing or sharing utensils and cups, through touching a sick person’s feces such as when changing diapers, or touching the eyes, nose or mouth after contact with contaminated surfaces.

Unlike cold sores and coxsackievirus blisters, thrush cannot be spread through saliva or kissing.

3. HIV and hepatitis B in saliva

Hepatitis B is transmitted through contact with body fluids infected with the virus, such as direct contact with blood or open wounds. Therefore, transmission can be through sharing toothbrushes, but not through sharing cutlery, kissing, coughing or sneezing, citing the Centers for Disease Control and Prevention (CDC).

Hepatitis C requires exposure to blood, and is usually spread through sharing needles or other equipment used to prepare and inject drugs. Hepatitis A requires some form of exposure to faeces (including contaminated water or food), and is not spread through saliva or kissing.

In general, kissing is not considered a risk factor for HIV transmission. It would only be a risk if there was bleeding or an open wound.

4. Natural microbial defense

Saliva has a natural cleansing role, which is provided by its rinsing activity. Other antimicrobial defenses in saliva include antibodies and other antimicrobial proteins (such as lysozyme).

Normal oral flora (good bacteria) prevent the growth of bad bacteria. You also have all kinds of viruses naturally in your body, including in your mouth.

You are more likely to get mouth infections when the natural resistance in your mouth is reduced. For example, gum infections can occur in people who are deficient in vitamin C.

Oral candidiasis, which is caused by a candida yeast infection is more likely to occur in people who have taken antibiotics.

Those are some infectious diseases that spread through saliva. Be careful, keep clean and healthy and always practice good personal hygiene, ok!
