hpv types

As per the Cleveland Clinic, Human Papillomavirus (HPV) is the most common Sexually Transmitted Infection that affects more than 14 million people every year.

Many sexually active people get affected by HPV at some point in their lives, and some people may have a high risk of developing cancers.

However, not all HPV encounters cause Cervical Cancer in people.

Then, what makes some HPV easily curable and others deadly?

HPV can be differentiated into two categories, i.e., low-risk and high-risk HPV types depending on its association with Cervical Cancer. 

This comprehensive article will elaborate on the HPV types and various important information associated with them.

Total number of HPV types

There are more than 150 types of HPV strains, and almost 40 affect the genital area but don’t pose a serious threat.

Generally, HPV does not show serious symptoms, and many people don’t know until the condition gets worse.

Fortunately, more than ninety percent of HPV infections go away or become undetectable within two years.

Still, some HPV types can stay for longer in the body and lead to serious complications, including Genital warts and cancer.

HPV can cause six types of cancers: Cancer include Cervical Cancer, Anal Cancer, Penile Cancer, Vaginal Cancer, Vulvar Cancer, and Oropharyngeal (middle part of the pharynx behind the mouth) Cancer.

Types of HPV

HPV infection can infect the basal epithelium layer of cells or the inner lining of the tissues.

Thus, it can be classified into two types:

  • Cutaneous types of HPV: The cutaneous type of HPV targets the skin of the hands and feet
  • Mucosal types of HPV: The mucosal types of HPV infect the lining of the mouth, respiratory tract, throat, and anogenital epithelium

Further, depending on their association with the risk of Cervical Cancer, they can be divided into two categories:

Low-risk types of HPV

Some HPV types do not cause symptoms and usually go away when the body boosts immunity against the infection-causing pathogen.

These types of HPV are called low-risk HPV types and have no association with cancers.

However, they can lead to Genital warts.

Some low-risk HPV types are 6, 11, 42, 43, and 44.

It can cause warts formation in the vulva, penis, vagina, scrotum, and anus in people.

Furthermore, warts may also appear in the mouth and throat.

When warts form in the respiratory tract, people may develop a condition called Respiratory Papillomavirus, which causes respiratory problems.

High-risk types of HPV

Complications may involve cancer

The high-risk types of HPV can lead to serious Cervical Dysplasia or Cervical Cancer.

HPV types are 16, 18, 31, 33, 34, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 70.

There are more than twelve types of high-risk HPV. 

However, only two types, 16 and 18, cause the majority of HPV-related complications.

The complications may involve cancers of the cervix, vagina, vulva, penis and anus.

About 99.7% of cases of Cervical Cancer are caused by persistent genital high-risk HPV-type infection.

Further, these HPV types, 16 and 18, can also cause cancer in the throat, tonsils, and tongue, called Oropharyngeal Cancer.

HPV types and diseases associated with them
