What diseases can be transmitted by saliva

Everyone knows that infectious diseases are transmitted in different ways, especially diseases that are transmitted through human body fluids. We must pay more attention to them. Saliva is also one of the human body fluids, so what diseases can be transmitted by saliva? Diseases that can be transmitted through saliva include AIDS, sexually transmitted diseases, and hepatitis virus. Although AIDS is not widely transmitted through saliva, it can be easily transmitted if there are wounds in the mouth.

AIDS is basically not transmitted through saliva, unless you have a wound in your mouth, you may be infected.

Kiss out AIDS

Can kissing spread AIDS? It depends on the extent of the kiss. When a light kiss, or polite kiss, occurs where the lips touch lightly, it does not spread HIV. During a deep and passionate kiss, the tongue enters the other person's mouth and there is an exchange of saliva between the two, which may lead to the spread of AIDS. If either party has oral mucosal ulcers, wounds or bleeding, the risk of transmitting AIDS will be greater.

Kissing out STDs

Sexually transmitted diseases such as syphilis and genital herpes can be transmitted through saliva. Syphilis is a sexually transmitted disease caused by Treponema pallidum, a chronic systemic lesion. Untreated syphilis patients are most contagious within 1 to 2 years after infection, and their saliva carries Treponema pallidum when their oral mucosa is broken. Genital herpes is a lesion of the genital skin and mucous membranes caused by the herpes simplex virus. Herpes simplex virus type 1 is transmitted through saliva and mainly causes herpes on the lips.

Kiss out an infectious disease

It has been confirmed that there are five types of hepatitis viruses, namely hepatitis A, B, C, D and E, which can cause corresponding hepatitis. Hepatitis B, C and D are mainly transmitted through the blood; hepatitis A and E are mainly transmitted through the digestive tract. The hepatitis virus can be detected in the saliva of hepatitis patients and can be transmitted through kissing.

Medical research shows that more than 80% of adults suffer from gingivitis to varying degrees, and about 2 to 3 ml of blood leaks from the gingival blood vessels into the mouth every day. Since the blood of hepatitis patients has poor coagulability, if they suffer from hepatitis and gingivitis at the same time, more blood will leak into the mouth from the gingival blood vessels every day, and the hepatitis virus will also leak into the mouth with the blood. When a hepatitis patient kisses someone deeply, the hepatitis virus can be transmitted to the other person. If the other person's oral mucosa is damaged or has gingivitis, once sucking occurs, the hepatitis virus will invade his blood and cause the spread of viral hepatitis.

Kissing can also spread infectious diseases such as influenza, tuberculosis, and typhoid because saliva carries the pathogens of these diseases.

Kissing stomach problems

Studies have shown that Helicobacter pylori infection is one of the important causes of chronic gastritis and peptic ulcer. The infection rate of Helicobacter pylori is 40% in urban areas and 60% in rural areas. There are large numbers of Helicobacter pylori in the mouths of people with chronic gastritis, gastric ulcers and duodenal ulcers. When such a patient kisses a healthy person, Helicobacter pylori is transmitted to the healthy person through the exchange of saliva.

Life is impossible without kissing. Kissing has its pros and cons. Should we kiss? I think it depends on the individual and it depends on your personal preference. However, it should be pointed out that patients suffering from AIDS, sexually transmitted diseases and infectious diseases should consciously refrain from kissing. If you know that the other person is suffering from this disease, you should not kiss him/her.
