Kiss
is mostly regarded as an expression of love between people
But do you understand that
Some diseases are spread through kissing?
EB virus (EBV) infected with
EB virus (EBV) is also known as the "kissing virus". This virus belongs to the DNA virus of human herpes virus . It is the first virus proven to be related to human tumors and is also the only double-stranded linear DNA virus that infected human .
EBV is mainly transmitted in people through contact between saliva and oral mucosa, and can also be transmitted through blood transfusion and sexual behavior. It is estimated that about 90% of adults worldwide have been infected with EBV, but most of them only show self-limiting latent infection.
EBV can invade the host's B lymphocyte (referred to as B cell ), T lymphocyte (referred to as T cell ) and natural killer cells (NK cells). EBV infection can lead to a variety of lymphocyte proliferation diseases, including non-neoplastic and neoplastic diseases. The former includes infectious mononucleosis (IM), chronic active EBV infection (cAEBV), EBV-associated hemophagocytosis (EBV-HLH), and the latter includes lymphoma .
Helicobacter pylori (Hp) infection
015 Kyoto Consensus Defines HP infection as an infectious disease. Since Hp was discovered, people's understanding of the causes of chronic gastritis, peptic ulcers, and other diseases has undergone revolutionary changes. With further research, it was found that Hp not only has a high natural infection rate, but can also be transmitted between people through oral and fecal and oral transmission channels.
Most Chinese people do not have the habit of sharing meals and are easily transmitted from one another. Intimate kissing is also one of the ways to contagious Hp. studies have shown that one couple who have been with more than 3 years has Hp, and the other party must have. Hp is closely related to many diseases including chronic gastritis and peptic ulcers, and can even cause cancer.
Hand, foot and mouth disease (HFMD)
This disease is well-known and is a common disease in infants and children. It is similar to herpes varicella. Its herpes occurs in the hands, feet and mouth, so it is called hand, foot and mouth disease.
virus exists in the pharynx, saliva, herpes and feces of sick children. It is transmitted through respiratory tract through cough , sneezing droplets, and can also be indirectly transmitted through hands, patient utensils, and food utensils. It often occurs in places with dense children such as kindergartens and primary schools, accounting for more than half. is especially the highest incidence rate in the age group under 3 years old. The infection between people is through direct contact with the infected person's nose and pharyngeal secretions or feces. Hand, foot and mouth disease is rarely transmitted through kissing, but not absolutely nothing.
AIDS
AIDS AIDS patients contain HIV in their saliva, but saliva transmits AIDS with prerequisites. Such as sneezing, eating together, etc. will not be transmitted.
However, if an AIDS patient has oral ulcers and bleeding, the kissing time is too long and the saliva is fully exchanged, and it is possible to get infected with AIDS.
Experts explain that HIV can indeed be found in saliva, but the amount of viruses in it is very small. HIV must reach a certain amount before it can cause transmission. Someone has calculated that if the virus in the saliva reaches the infection amount, I am afraid that more than 20 milliliters of the infected person's saliva will be swallowed at a time. Therefore, under normal circumstances, saliva will not transmit AIDS.
syphilis
syphilis is a sexually transmitted disease infected by spirochetes of syphilis through direct contact.
congenital syphilis, also known as fetal syphilis , is transmitted to the fetus by the sick mother through the placental blood flow.Acquired syphilis is mainly transmitted by sexual intercourse, followed by kissing, breastfeeding, etc. The most contagious syphilis lesions are early damage, such as chancre. So, kissing can lead to the spread of syphilis .
hepatitis virus
Currently, five types of viruses A, B, C, D and E are found, which can cause the corresponding hepatitis.
Among them, hepatitis B, C, and D viruses are transmitted through blood, while hepatitis A and E viruses are transmitted through fecal-oral route.
Hepatitis virus can be isolated from the saliva of patients with hepatitis. If both parties who are kissing have oral ulcers or bleeding problems, hepatitis can be transmitted through kissing.
kissing has both advantages and disadvantages, but if you have the above diseases, it is better to tell the other party. Respect others is also respecting yourself. The important thing is that you must seek medical treatment in in time.
