Human papillomavirus, or HPV, is a virus that most sexually active people will encounter at some point in their lives. With over 100 different types, HPV is incredibly common. Fortunately, in most cases, the body can clear the infection without any symptoms. However, certain strains of HPV can lead to more serious health issues down the line.
HPV is a contact infection, meaning it stays in the cells near where it enters the body instead of spreading throughout. This virus is usually transmitted through sexual activity, affecting areas like the vagina, vulva, penis, anus, mouth, and throat.
While we can test for HPV in these areas, routine testing isn’t widespread. This is because, although we can treat health problems caused by HPV, there’s no cure for the virus itself. Testing would reveal many positive results, but without a treatment to clear the virus, these tests wouldn’t change the management of the infection.
The immune system is often capable of eliminating most HPV strains before they cause harm, often without the person even realizing they were infected. However, some strains, like HPV 6 and 11, can cause cell changes that lead to genital warts. These warts are contagious and usually treated with topical creams, but they don’t typically cause long-term damage.
More concerning are 13 other strains that can cause DNA mutations, leading to rapid cell division and potentially cancer. The cervix is particularly vulnerable, with HPV 16 and 18 responsible for most cervical cancer cases. Cervical cancer is the fourth most common cancer in women, and it can take up to 20 years for symptoms to appear. Regular screening can detect cell changes in the cervix before they turn cancerous.
Women over 21 can have regular pap smears, where a small sample of cervical tissue is taken to check for abnormal cells. A positive result doesn’t mean cancer is present, but it indicates potential future risk. Depending on the severity, patients might need more frequent pap smears or a procedure called a colposcopy, where a doctor examines the cervix more closely and may take a biopsy. In some cases, abnormal tissue is removed.
HPV can also lead to throat infections that may cause head and neck cancers, but there isn’t a pap smear equivalent for the throat. Using condoms can help reduce HPV transmission during sex. Additionally, there are three safe and effective vaccines targeting HPV 16 and 18. These vaccines are administered in two or three doses over several months and are most effective when all doses are completed. Many countries include the vaccine in standard care for individuals aged 11 to 18, and it’s increasingly available to boys. Adults in countries like the United States and the United Kingdom can also choose to get vaccinated. Research suggests that vaccination could lower cervical cancer rates worldwide by nearly 90%.
Researchers are working on an injection for those already infected with HPV 16 and 18, aiming to prevent infected cells from becoming cancerous. While there’s room for improvement in screening, treatment, and access to these services, using condoms, getting vaccinated, and undergoing cervical screening can significantly reduce the risks associated with HPV.
Create a campaign to raise awareness about HPV among your peers. Design posters, social media posts, or short videos that highlight key facts about HPV, its transmission, and prevention methods. This activity will help you understand the importance of public health education and communication.
Engage in a debate where you and your classmates take on roles as healthcare professionals, patients, and policymakers. Discuss the pros and cons of HPV vaccination, screening, and public health strategies. This will enhance your understanding of different perspectives and the complexities involved in healthcare decision-making.
Analyze a case study of a patient diagnosed with HPV-related health issues. Discuss the patient’s journey, from diagnosis to treatment options, and explore the psychological and social impacts. This activity will deepen your comprehension of the real-world implications of HPV.
Participate in a workshop where you learn about the HPV vaccine’s development, effectiveness, and safety. Engage in hands-on activities such as creating informative brochures or conducting mock vaccination drives. This will provide practical insights into vaccine advocacy and public health initiatives.
Conduct research on the latest developments in HPV prevention and treatment. Present your findings to the class, focusing on innovative strategies and future directions in HPV management. This will enhance your research skills and keep you informed about cutting-edge advancements in the field.
At some point, most sexually active individuals will be infected with human papillomavirus, or ‘HPV.’ There are over 100 types of HPV, and most of the time, the body eliminates infections without symptoms. However, some strains can pose serious health risks in the future. HPV causes contact infections, meaning the virus remains in the cells near the point of infection rather than spreading throughout the entire body. Since HPV is often transmitted through sexual activity, this typically affects the cells of the vagina, vulva, penis, anus, mouth, and throat.
We can test for HPV in cells from these areas, but while testing for the virus is scientifically possible, it isn’t common. The main reason is that, although there are treatments for the adverse health effects caused by HPV, there’s no treatment for the virus itself. Therefore, testing for HPV would yield many positives, and while most of them won’t be cause for concern, there is still no treatment plan for clearing the body of the virus.
There are effective ways to protect yourself from HPV. The body’s immune system can eradicate most strains of HPV before they cause any harm, often without individuals even knowing they’ve been infected. Certain strains, like HPV 6 and 11, can cause abnormalities in the cells of the infected tissue, leading to genital warts. While these are infectious and require treatment, usually with topical creams, wart-causing strains don’t typically create long-term damage.
However, another 13 strains can cause DNA mutations that lead to faster-than-normal cell division, potentially resulting in cancerous growths. The cells of the cervix are especially at risk. Two strains in particular—HPV 16 and 18—are responsible for the majority of cervical cancer cases, which is now the fourth most common type of cancer in women. It can take up to 20 years for cancer symptoms to appear, but with regular screening, we can discover cellular abnormalities in the cervix before they develop into cancer.
Women over 21 can undergo regular pap smears, where a sample of tissue is gently scraped from the lining of the cervix to test for abnormal cells. A positive test doesn’t mean the person has cervical cancer; rather, it indicates that there are irregular cells in the cervix that could develop into cancer in the future. Patients are then either monitored with more frequent pap smears or, for more severe irregularities, undergo a procedure called a colposcopy. This involves a doctor examining the cervix through a microscope and possibly taking a small biopsy of tissue for closer examination. In some cases, the affected tissue may be removed.
HPV infections of the throat may lead to head and neck cancers, but currently, there’s no equivalent of the pap smear for the throat. Using condoms helps prevent the spread of HPV during sexual activity. There are also three safe, effective vaccines that target HPV 16 and 18. The vaccine is administered in two or three doses a few months apart and is most beneficial when all doses are received. Currently, the vaccine is part of standard care for individuals aged 11 to 18 in many countries, and it is increasingly becoming available to boys as well. Adult women and men in countries including the United States and the United Kingdom can opt to receive the vaccine, and evidence suggests that vaccination could reduce the worldwide incidence of cervical cancer by almost 90%.
Researchers are also developing an injection for individuals already infected with HPV 16 and 18, which would target the infected cells to prevent them from developing into cancerous ones. While there’s still room for improvement in screening, treatment, and access to these services, condom use, vaccination, and cervical screening can each reduce the harm caused by HPV.
