Herpes Simplex (Cold Sores and Genital Herpes)
Specialty: Dermatology
Category: Skin Disorders
Sub-category: Infectious Skin Diseases - Viral Infections
Symptoms:
painful blisters or ulcers; burning or tingling sensation before lesions appear; cold sores around the mouth; genital sores in genital herpes; fever and malaise in severe cases
Root Cause:
Infection with Herpes Simplex Virus (HSV-1 or HSV-2), characterized by latent and recurrent episodes.
How it's Diagnosed: videos
Clinical examination; PCR testing or viral culture for confirmation; serology for HSV antibodies.
Treatment:
Antiviral medications to reduce severity and recurrence.
Medications:
Antivirals (e.g., acyclovir , valacyclovir , famciclovir ).
Prevalence:
How common the health condition is within a specific population.
HSV-1 affects approximately 67% of the global population, and HSV-2 affects about 13%.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Close contact with infected individuals, immunosuppression, and stress.
Prognosis:
The expected outcome or course of the condition over time.
Recurrent but manageable; antivirals can reduce frequency and severity.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Keratitis (eye infection); Encephalitis; Neonatal herpes
Varicella (Chickenpox)
Specialty: Dermatology
Category: Skin Disorders
Sub-category: Infectious Skin Diseases - Viral Infections
Symptoms:
itchy, blister-like rash; red spots that progress to fluid-filled blisters; fever; fatigue; loss of appetite
Root Cause:
Primary infection with Varicella-Zoster Virus (VZV).
How it's Diagnosed: videos
Clinical presentation; PCR testing or serology in atypical cases.
Treatment:
Symptomatic care for most cases; antivirals for high-risk individuals.
Medications:
Antivirals (e.g., acyclovir , valacyclovir ) for severe cases. Antihistamines (e.g., diphenhydramine ) – for itching.
Prevalence:
How common the health condition is within a specific population.
Highly contagious; incidence has decreased significantly with vaccination.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Close contact with infected individuals, unvaccinated status, and immunosuppression.
Prognosis:
The expected outcome or course of the condition over time.
Excellent in children; adults and immunocompromised individuals are at higher risk of complications.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Secondary bacterial infections; Pneumonia; Encephalitis
Herpes Zoster (Shingles)
Specialty: Dermatology
Category: Skin Disorders
Sub-category: Infectious Skin Diseases - Viral Infections
Symptoms:
painful, blistering rash along a single dermatome; burning or tingling sensation; fever; fatigue
Root Cause:
Reactivation of latent Varicella-Zoster Virus in sensory nerve ganglia.
How it's Diagnosed: videos
Clinical examination; PCR testing or viral culture for confirmation.
Treatment:
Antiviral medications and pain management.
Medications:
Antivirals (e.g., acyclovir , valacyclovir , famciclovir ). Analgesics (e.g., ibuprofen , acetaminophen ) – for pain relief. Neuropathic pain medications (e.g., gabapentin ) – for post-herpetic neuralgia.
Prevalence:
How common the health condition is within a specific population.
Affects 1 in 3 people in their lifetime; more common in older adults.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Aging, immunosuppression, and stress.
Prognosis:
The expected outcome or course of the condition over time.
Resolves in 2–4 weeks; post-herpetic neuralgia can persist.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Post-herpetic neuralgia; Ocular complications (if involving the eye); Dissemination in immunocompromised patients
Molluscum Contagiosum
Specialty: Dermatology
Category: Skin Disorders
Sub-category: Infectious Skin Diseases - Viral Infections
Symptoms:
small, flesh-colored or pink dome-shaped bumps with central dimpling; mild itching or redness; commonly affects face, trunk, and extremities
Root Cause:
Viral infection caused by the Molluscum Contagiosum Virus (MCV), a member of the poxvirus family.
How it's Diagnosed: videos
Clinical examination based on characteristic appearance; biopsy in atypical cases.
Treatment:
Often self-limiting; physical removal or topical treatments in persistent cases.
Medications:
Topical therapies (e.g., cantharidin , imiquimod ). Cryotherapy – for lesion removal.
Prevalence:
How common the health condition is within a specific population.
Common in children and immunocompromised individuals.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Close contact with infected individuals, sharing personal items, and immunosuppression.
Prognosis:
The expected outcome or course of the condition over time.
Resolves spontaneously in 6–12 months; treatment accelerates clearance.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Secondary bacterial infections; Spreading to other areas
Warts (Human Papillomavirus)
Specialty: Dermatology
Category: Skin Disorders
Sub-category: Infectious Skin Diseases - Viral Infections
Symptoms:
rough, raised lesions; common warts on hands and feet; flat warts on face or legs; plantar warts on soles of feet
Root Cause:
Infection with Human Papillomavirus (HPV), causing overgrowth of keratinocytes.
How it's Diagnosed: videos
Clinical examination; biopsy for atypical lesions.
Treatment:
Physical removal, topical treatments, or cryotherapy.
Medications:
Topical salicylic acid – to soften and remove warts. Cryotherapy (liquid nitrogen) – to destroy warts. Immunotherapy (e.g., imiquimod ) – for persistent cases.
Prevalence:
How common the health condition is within a specific population.
Common, especially in children and young adults.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Direct contact with infected skin, immunosuppression, and cuts or abrasions.
Prognosis:
The expected outcome or course of the condition over time.
Most warts resolve within 1–2 years; treatment accelerates resolution.
