What are the preventive measures for cervical HPV virus?

HPV virus is a virus that people are relatively familiar with. This virus can infect multiple parts of the human body. For example, it is very easy to infect the skin, and it is also easy to infect human mucous membrane tissue, especially the cervix of women. Many people may think that HPV virus is a specific type of virus, but it is not. More than 100 types of HPV viruses have been discovered. Different HPV virus infections have different symptoms, but the harm is great, so you must take preventive measures in your daily life.

one. HPV Prevention HPV Prevention.

The key is to administer the vaccine as early as possible (generally required for women aged 9-26, with no history of sexual activity and HPV infection), but unfortunately it has not yet been developed and marketed in mainland China. The study suggests that vaccines targeting HPV16/18 can prevent most cervical cancers (66.2%), anal cancers (79.4%), oropharyngeal cancers (60.2%), vaginal cancers (55.1%), and many penile cancers (47.9%) and vulvar cancers (48.6%). The quadrivalent (HPV6, 11, 16, 18) vaccine is currently widely used. The US FDA has newly certified a 9-valent vaccine (the clinical effectiveness is not yet clear and is still controversial). In short, the application of HPV vaccine has greatly reduced HPV-related cancers. I hope it can be launched in China as soon as possible so that the incidence rate of cervical cancer in China can reach the level of developed countries. The industry is moving towards the 4.0 era, so why can't medical care move forward?

two. Reasons why women's cervix is ​​susceptible to HPV infection

Why HPV can easily infect the cervix and cause cervical cancer is closely related to the anatomical structure of the cervix. In the previous topic, we talked about the junction of the squamocolumnar epithelium in the cervix (just like the Golden Triangle, where evil forces are entrenched and endanger the entire society). The immature metaplastic squamous epithelium in the transformation zone proliferates actively and once exposed to continuous stimulation from HPV, it is more likely to develop cervical precancerous lesions (which will be discussed in detail in the fourth topic).

How is HPV transmitted?

three. Transmission routes of HPV infection in women

How HPV is spread. The main route of HPV infection is sexual contact (then everyone should understand why HPV can also cause anal cancer, oropharyngeal cancer, penile cancer, oral cancer, and laryngeal cancer). However, HPV is very resilient and can still be spread through close contact in daily life. Even condoms cannot prevent the spread of HPV (regular sexual partners and safe use of condoms will greatly reduce the probability of HPV transmission. It is safer to use condoms). Multiple sexual partners, early sexual activity (before 18 years old), and smoking are other high-risk factors for the occurrence of cervical cancer (healthy living, early to bed and early to rise, physical exercise, and improving the body's immunity are the most important).
