What is the cause of cervical warts

Everyone finds sexually transmitted diseases very scary because they can be transmitted to the people they love without people knowing. So what are the causes of these diseases? People often say that cervical warts are a type of sexually transmitted disease, which makes many patients terrified and miserable. How to get rid of cervical warts is a problem that troubles many patients. But what causes cervical warts? There is no clear answer in people's minds. The following is an introduction to the causes of cervical warts:

Cervical warts are caused by HPV. HPV is a DNA virus with a double-stranded DNA core and a protein capsid wrapped around it. The capsid is composed of 72 subunit shell particles. They are arranged into a three-dimensional symmetrical icosahedron. The double-stranded DNA and the outer shell wrapped around it are collectively called the nucleocapsid. The core DNA double-stranded constitutes the HPV genome, which consists of 7,900 nucleotide bases. They encode about 9 protein components. E1-E7, L1, and L2 are 9 genes that encode proteins, respectively. The E group genes are genes required for viral DNA replication. The L1 and L2 genes encode viral particle capsid proteins.

Papillomaviruses are highly species-specific to their hosts, and the only host of HPV is humans. Experimental animals, including rodents, cannot be infected, and tissue culture of HPV has not yet been successful, which brings certain difficulties to research work.

There are many different types of HPV. In the past, serological methods were mostly used to type HPV based on the specificity of antiserum binding to HPV capsid protein. However, since HPV has not yet been cultured, it is impossible to prepare antigens and corresponding antiserum in large quantities, and serological typing methods are difficult to apply in practice. The emergence of molecular biology technology has enabled us to type HPV based on genotypes. Using molecular hybridization technology, more than 120 subtypes have been identified, about 40 of which are related to reproductive tract infections. Different types of HPV can cause different clinical manifestations.

HPVs associated with cervical cancer and cervical intraepithelial neoplasia are called high-risk types, including types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, etc. HPVs associated with benign lesions such as genital cervical condyloma are called low-risk types, including types 6, 11, 42, 43, 44, etc. Persistent infection with high-risk HPVs is the main cause of cervical cancer.

Conclusion: After reading the above article about cervical warts, I believe you have a preliminary understanding of the cause of cervical warts! People get scared and lose confidence in life when they hear about sexually transmitted diseases. In fact, cervical warts are not as scary as people imagine. You should keep a calm mind, believe in science, and deal with it calmly.
