HPV (Human Papillomavirus) is a virus that is most often transmitted during sexual intercourse through direct skin contact. There are over one hundred differing kinds of HPV. Most men and women with the infection are unaware of it because they do not have any symptoms or health problems. But in some cases, certain types of HPV can cause warts (abnormal and non-cancerous mass on the skin on different parts of the body) or genital warts. In other cases, certain types of HPV can cause precancerous lesions (areas with abnormal tissue) or cancer.
Most types of viruses do not cause symptoms and go away on their own. But some can cause cervical cancer in women and some less common cancers, such as anal, penis, vaginal cancers, and oropharynx (behind the throat include the base of the tongue and tonsils). Other types of human papillomavirus include genital warts in men and women, which are called genital warts.
Genital warts are not a life-threatening condition, but they can cause stress and treat them with pain and headaches. The severity and risk of the disease are higher in those who have a defective immune system.
Human papillomavirus transmission
The virus is transmitted to a healthy person through close contact with the infected person's skin or mucous membranes, the disease is highly contagious.
Approximately 60 types of HPV have the ability to cause normal warts, which occur in certain areas of the body, such as the hands and feet. About 40 of these viruses are called "genital type" viruses, which can cause genital warts. These viruses are usually spread from person to person during sexual intercourse during intercourse through the vagina or anus. The virus also can be transmitted through oral sex. HPV is that the most typical reason for sexually transmitted diseases.
This virus has more transmission power than the common wart virus (other parts of the body). Warts are not always clearly seen in an infected person (especially in men).
Symptoms and forms of the disease
In most cases, the immune system fights the virus and prevents the disease from developing. The virus is often asymptomatic in men or disappears on its own. In many cases, warts are so small that they are not easily seen, which is why most people are unaware that they have the disease. Some people are aware of it due to the appearance of warts or having abnormal Pap smears.
Warts are usually in the form of soft, moist, solid skin protrusions about 2 mm in size, with a smooth or uneven surface that is either slightly darker or lighter in color;Sometimes solitary and sometimes interconnected and seen in the form of cauliflower masses;Usually painless with no itching, but sometimes they may be itchy. These warts are usually painless unless they are in an area that is irritated. Few women complain of pain, itching, burning, or bleeding at the site of the lesion. The most common lesions in women are in the vulva, vagina, cervix, anus and groin, and in men, the penis, scrotum, thigh and groin.
There is no specific treatment that can eradicate the virus and prevent its recurrence.
There are a variety of treatments, some of which use medication and some of which are practical. Maintaining good hygiene and keeping the lesion clean helps to heal. Practical methods include cryotherapy (freezing the lesion with liquid nitrogen), electrocautery (removing the lesion with electric current), and laser therapy (removing the lesion with laser beam).
The above measures reduce the likelihood of the virus spreading and relieving pain or itching of the warts that are seemingly unpleasant and may be difficult to keep them clean.
Removing genital warts does not mean that the person is no longer infected with HPV. Warts may come back later, as the virus may still remain healthy and active in other cells.
An HPV-infected person who has no obvious warts can also infect their sexual partner with the virus. An infection that is not active may become active when a person's immune system is weakened due to the treatment of other diseases, such as cancer.
