HPV vs HIV: Understanding the Differences, Risks, and Prevention
Human Papillomavirus (HPV) and Human Immunodeficiency Virus (HIV) are two prevalent STIs that share a connection through their mode of transmission.
According to CDC, in the United States, approximately 79 million individuals are affected by the Human Papillomavirus (HPV) and HIV impacts an estimated population of over 1.1 million individuals.
While they have different symptoms, causes, and treatments, there is a notable link between them, especially concerning the increased risk of certain health complications.
This article aims to delve into the characteristics of HPV vs HIV, their link, symptoms, risk factors, prevention, and treatments.

What is HPV
HPV, the most prevalent Sexually Transmitted Infection (STI), has over 150 strains.
Most people may not exhibit symptoms, but some types can cause genital warts and lead to cancers.
The HPV vaccine has been effective in reducing the incidence of genital warts and various cancers.
It is recommended for individuals aged 11-26, with exceptions made for those up to age 45 in some cases.
What is HIV
HIV, a virus that weakens the immune system, primarily spreads through sexual intercourse or sharing drug injection equipment.
Antiretroviral drugs help manage HIV by reducing viral load, increasing CD4 cells, and preventing transmission.
Regular treatment allows individuals with HIV to lead healthy lives, although there is no cure.
The link between HPV and HIV
While HPV and HIV are distinct viruses, they share the commonality of being sexually transmitted.
Research suggests that individuals with untreated HIV may be more susceptible to active HPV infections.
It can also potentially increase the risk of developing cancers associated with HPV.
Conversely, there is also evidence that having HPV may increase the risk of acquiring HIV, although the mechanisms are not entirely clear.
Symptoms of HPV and HIV
Symptom manifestation differ between HPV and HIV and they may not always be immediately apparent.
HPV symptoms
HPV infections often remain asymptomatic, especially in individuals with healthy immune systems.
- Some cases can manifest as genital warts, appearing in the genital region, anus, mouth, or throat
- Warts can also develop on various body parts like hands, feet, legs, and the face
- High-risk HPV strains elevate the likelihood of certain cancers, notably cervical cancer
- Other cancers associated with high-risk HPV include vulva, vagina, penis, anus, and throat cancers
HIV symptoms
HIV infections frequently don’t present immediate physical symptoms, and individuals might not be aware they’re infected.
Early Symptoms include:
- Fever
- Rash
- Enlarged lymph nodes
- Joint pain
- Diarrhea
- Night sweats
Risk factors for HPV vs HIV
Engaging in sexual activity, including oral, vaginal, or anal sex, poses a risk for both HPV and HIV.
Skin-to-skin contact, especially with infected areas on the hands, feet, or oral/genital mucous membranes, can transmit HPV.
Additionally, HPV infects surface skin cells and mucous membranes, allowing transmission through various contact points with an infected person.
HIV transmission occurs through various bodily fluids, including blood, breast milk, and sexual fluids.
Moreover, exposure to pre-seminal or vaginal fluids of an HIV-positive person can also lead to transmission.
Sharing needles during intravenous drug use is a significant method of HIV transmission.
Diagnosis
There are different methods of diagnosing HIV and HPV.
Diagnosis of HPV
To diagnose HPV, sometimes a visual examination is enough, and sometimes some tests are conducted.
These tests include:
- Visual examination: Doctors can often diagnose HPV by visually inspecting warts on the genitals, anus, or mouth. A vinegar solution may be used to make warts more visible
- Pap test: Pap smears can detect abnormal cervical cells, indicating the presence of certain HPV strains
- Symptom observation: Genital warts or severe complications like cancer might prompt awareness of an HPV infection
Diagnosis of HIV
HIV diagnosis includes tests such as:
- Antibody tests: Detect antibodies produced in response to HIV. A window period of up to 12 weeks after exposure exists for accurate detection
- NAT tests: This detects the presence of the virus in the blood. This is the first test to become positive after contracting the virus
- Home testing: Some tests involve a gum swab. Negative results may require retesting, and positive results should be confirmed by a healthcare professional
Treatment methods
There is no direct treatment for HPV. The immune system often clears the virus naturally within 2 years.
Healthcare professionals may treat resulting genital warts or cancers caused by HPV.
HIV is treatable with a combination of antiretroviral drugs.
These drugs:
- Reduce the viral load in the blood
- Increase CD4 white blood cells, strengthening the immune system
- Halt the progression of HIV
- Prevent the spread of HIV to others
Proper treatment can lead to an undetectable viral load, meaning the virus is not progressing, and the individual cannot sexually transmit the virus.
Prevention methods
HPV and HIV can be prevented by many methods which include:
Barrier contraceptive methods
Condoms are effective in reducing the transmission of HIV by 85%. While they may not fully protect against HPV, they still provide a level of prevention.
Vaccination
Individuals aged 9 to 45 can receive the HPV vaccine, which is highly effective in preventing 90% of HPV-related cancers.
Unlike HPV, there is no vaccine for HIV.
Screenings
Regular screenings are essential since both HPV and HIV may not show symptoms.
For HPV, Pap smears are recommended every 3 years for individuals with vaginas between the ages of 21 and 29.
Those over 30 can opt for an HPV test every 5 years.
Regular blood tests for HIV are recommended for everyone aged 13-64, with high-risk individuals needing testing at least once a year.
Preexposure Prophylactic (PrEP)
PrEP, when used daily, can reduce the risk of contracting HIV through sexual activity by around 99%.
It is a key preventive strategy, especially for individuals at high risk and those sharing drug-injecting equipment.
Conclusion
While HPV and HIV are transmitted through sexual activity, they differ significantly in their nature, symptoms, and available preventive measures.
The development of vaccines, such as Gardasil 9, has proven effective in preventing various strains of HPV and reducing the incidence of genital warts and associated cancers.
Early detection through visual examination and Pap tests remains crucial, particularly for those at higher risk.
On the other hand, HIV weakens the immune system and can lead to severe health complications if left untreated.
Antiretroviral drugs have revolutionized HIV management, allowing individuals to lead healthy lives.
Regular screenings, including antibody tests and advanced diagnostic methods, are vital for early detection and prompt intervention.
Barrier methods like condoms, vaccination, and regular screenings play a pivotal role in reducing the prevalence and impact of both HPV and HIV.
Promoting safe sexual practices, regular screenings, and embracing preventive measures are integral components of minimizing the impact of HPV and HIV.
