HPV (Human Papillomavirus) is a frequently mentioned term in the health field. Many people immediately associate HPV with serious illnesses, but in reality, HPV infection is extremely common, and most people will experience at least one HPV infection in their lifetime.
To avoid misunderstanding and panic, we need a comprehensive understanding of HPV, including what it is, how it is transmitted, the possible health effects, and how the body responds.
1. What is HPV?
HPV is a type of DNA virus belonging to the papillomavirus family. Currently, there are more than 200 known subtypes. Based on the risk of causing disease, they are generally divided into:
-
Low-risk HPV : often causes benign lesions of the skin or mucous membranes, such as common warts or genital warts.
-
High-risk HPV : Some subtypes are associated with the occurrence of precancerous lesions or cancer, such as HPV-16 and HPV-18.
It’s important to note that being “high risk” for HPV doesn’t mean you’ll develop cancer if you’re infected. The vast majority of infections are temporary.
2. How HPV is Transmitted
HPV is mainly transmitted through direct contact between the skin and mucous membranes .
-
Sexual transmission : This is the most common way of transmission and includes vaginal, anal, and oral sex.
-
Skin-to-skin contact : Some HPV types can be spread through close skin-to-skin contact, such as common warts on the hands or feet.
-
Mother-to-child transmission : In rare cases, a pregnant woman can pass the virus to her newborn.
Misunderstanding clarification:
-
HPV is not spread through toilets, everyday handshakes, or shared eating utensils.
-
Using condoms can reduce the risk of HPV infection, but it cannot completely prevent it because the virus can be present in uncovered areas of skin.
III. Epidemiological Status of HPV Infection
-
According to data from the World Health Organization, approximately 80% of the world's population will be infected with HPV at least once in their lifetime .
-
Most infected people do not have obvious symptoms.
-
Studies have shown that over 90% of infections are cleared naturally by the immune system within 1–2 years .
That said, HPV infection is common and most cases resolve on their own. Only a small percentage of persistent infections can cause serious health problems.
4. Symptoms of HPV infection
Most people infected with HPV do not have any symptoms , and the infection is often discovered during a physical examination or screening.
Possible scenarios include:
-
Genital warts (caused by low-risk HPV)
-
Abnormal cervical cytology (occurs with persistent infection with some high-risk HPV types)
-
Other less common sites of lesions, such as the oropharynx
Therefore, regular screening and maintaining good immune status are very important.
5. How does the human body eliminate HPV?
The body's immune system plays a decisive role in the HPV clearance process:
-
Cellular immune response : T cells and natural killer (NK) cells recognize and eliminate infected cells.
-
Local immunity : Immune cells in mucosal tissues play a barrier role.
-
Long-term memory : The body forms immune memory against some HPV types, reducing the risk of reinfection.
Factors affecting immune clearance:
-
Age (young people are more likely to clear)
-
Lifestyle (smoking and alcohol abuse can reduce immunity)
-
Chronic stress, lack of sleep, etc. may also affect immune efficiency
VI. Directions of International Research
Researchers are exploring HPV from multiple perspectives:
-
Vaccination : HPV vaccines are currently available that can effectively prevent infections with a variety of high-risk and low-risk HPV types.
-
Screening methods : HPV DNA testing has been widely used for cervical cancer screening.
-
Immune support research : Some research has looked at the potential of natural ingredients, such as shiitake mycelium extract, to support immunity, but more clinical evidence is needed.
These studies provide new ideas for better understanding and management of HPV infection.
7. HPV common sense that the public needs to remember
-
HPV is not a rare disease : it is as common as the common cold and the vast majority of people will experience infection.
-
Infection ≠ Cancer : Most infections resolve on their own within two years.
-
Immunity is key : maintaining a healthy lifestyle helps the body eliminate viruses.
-
Scientific prevention : Risks can be effectively reduced through safe sex, vaccinations and regular screening.
8. Summary
HPV is a common virus. Most infections are temporary and cleared by the immune system. A better understanding of HPV among the public can help reduce unnecessary panic and misunderstanding.
The scientific attitude is:
-
Do not underestimate the risk of infection
-
Do not exaggerate its harm
-
Face HPV rationally through a healthy lifestyle and scientific prevention methods
Rational cognition + scientific management is the best way to deal with HPV.
