Human PapillomaVirus: Causes, Symptoms and Prevention

Understanding HPV Infection
Human Papillomavirus (HPV) infections often go unnoticed because the body’s immune system usually clears the virus before any symptoms develop. However, when symptoms do appear, they are typically in the form of warts, which vary based on the type of HPV involved.
Genital Warts
These warts are commonly associated with certain strains of HPV and appear as small, cauliflower-like bumps or flat lesions. In women, genital warts are primarily found on the vulva, but they can also appear near the anus, on the cervix, or within the vagina. In men, these warts typically appear on the penis, scrotum, or around the anus. Although genital warts are usually not painful, they may cause itching or tenderness.
Common Warts
These warts generally appear as rough, raised bumps and are most often found on the hands and fingers. While common warts are typically harmless, they can be unsightly and, in some cases, painful or prone to bleeding if they are injured.
Plantar Warts
Found on the heels or balls of the feet, plantar warts are hard, grainy growths that can cause discomfort, especially when walking or standing.
Flat Warts
These warts are slightly raised and have a flat top. They can appear on various parts of the body, with children often developing them on the face, men on the beard area, and women on the legs.
Understanding these symptoms is important for early identification and management. If you suspect you have warts or are experiencing any unusual growths, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
Cervical Cancer and HPV
Cervical cancer is primarily caused by human papillomavirus (HPV) infections. However, it often takes 20 years or more for cervical cancer to develop after an HPV infection. In its early stages, both HPV infection and cervical cancer usually do not produce noticeable symptoms. Therefore, vaccination against HPV is a crucial preventive measure.
Because early cervical cancer does not present symptoms, regular screening is essential for detecting precancerous changes in the cervix before cancer develops. Women should follow these screening guidelines:
Ages 21 to 29
It is recommended to have a Pap test (or Pap smear) every three years to check for any abnormal cells that could indicate a risk of cervical cancer.
Ages 30 to 65
Women should continue to have a Pap test every three years. Alternatively, they can choose to have the Pap test every five years if it is combined with an HPV DNA test, which detects the presence of HPV in the cells.
Over 65
Women can stop screening if they have had three consecutive normal Pap tests or two HPV DNA tests combined with Pap tests that showed no abnormalities.
Regular screenings are essential for early detection and prevention of cervical cancer. If you are due for a screening or have questions about your risk, consult your healthcare provider for personalized advice.
Causes of HPV Infection
HPV (human papillomavirus) infection occurs when the virus enters your body, typically through a small cut, scrape, or tear in the skin. The virus spreads mainly through direct skin-to-skin contact.
Genital HPV infections are most commonly transmitted through sexual activities, including vaginal intercourse, anal sex, and other types of skin-to-skin contact in the genital area. Some HPV types can also lead to infections in the mouth or throat, which are usually contracted through oral sex.
For pregnant women with HPV, there is a small risk that the virus may be passed to the baby during childbirth. Although rare, this can sometimes result in a noncancerous growth in the baby’s voice box (larynx), a condition known as recurrent respiratory papillomatosis.
Warts caused by HPV are contagious. They can spread through direct contact with a wart or by touching objects that have come into contact with a wart, such as towels or other personal items.
Risk Factors for HPV Infection
HPV (human papillomavirus) infections are quite common, and several factors can increase your risk of contracting the virus:
Number of Sexual Partners
Having multiple sexual partners increases the likelihood of acquiring a genital HPV infection. Additionally, having sex with a partner who has had numerous previous partners also raises your risk.
Age
HPV-related warts vary by age. Common warts are most frequently seen in children, while genital warts are more common in adolescents and young adults.
Weakened Immune System
Individuals with weakened immune systems are at higher risk of HPV infections. This includes people with conditions like HIV/AIDS or those taking immunosuppressive medications, such as those used after organ transplants.
Damaged Skin
Skin that has been punctured, cut, or otherwise damaged is more susceptible to developing common warts.
Personal Contact
HPV can spread through direct contact with someone’s warts. Additionally, touching surfaces that may have been exposed to HPV, such as in public showers or swimming pools, without proper protection can also increase your risk.
Complications of HPV Infection
HPV infections can lead to several health issues, including:
Oral and Upper Respiratory Lesions
Some HPV infections can cause growths or lesions in areas such as the tongue, tonsils, soft palate, or the larynx and nose.
Cancer
Certain types of HPV are known to increase the risk of developing cancer. These strains can lead to cervical cancer and may also contribute to cancers in the genitals, anus, mouth, and upper respiratory tract.
Recognizing these potential complications highlights the importance of prevention and early detection of HPV-related conditions.
