Summary
Adolescents face high rates of human papillomavirus (HPV) infection. Early screening and HPV vaccination before sexual activity are crucial for preventing persistent infections and related cancers.
Area of Science:
- Adolescent health
- Infectious diseases
- Gynecologic oncology
Background:
- Sexually active adolescents have the highest rates of prevalent and incident human papillomavirus (HPV) infections.
- Most HPV infections are transient, but persistence is linked to high-grade squamous intra-epithelial lesions (HSIL) and invasive cancer.
Purpose of the Study:
- To understand the natural history of HPV in adolescents.
- To inform optimal screening and treatment strategies for HPV in this population.
Main Methods:
- Review of existing literature on HPV natural history in adolescents.
- Analysis of the association between HPV persistence, cytologic abnormalities, and cancer development.
Main Results:
- High HPV infection rates (50-80%) occur within 2-3 years of initiating intercourse.
- Persistent HPV infections are strongly associated with HSIL and invasive cancer, though HSIL progression to cancer is not rapid.
- Watchful observation is a viable strategy for ASCUS and LSIL detected in adolescents.
Conclusions:
- Understanding HPV natural history guides management strategies like observation for low-grade lesions.
- Timely screening and HPV vaccination prior to sexual activity are essential for prevention in adolescents.

Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
