Overview
Shingles, or herpes zoster, is a viral infection that causes a painful skin rash. It results from the reactivation of the varicella-zoster virus—the same virus responsible for chickenpox. In Korea, shingles is particularly common among older adults and people with weakened immune systems. Due to Korea’s aging population, awareness and vaccination against shingles are increasing.
What is Shingles?
Shingles occurs when the dormant chickenpox virus becomes active again, often years later. The condition is marked by a painful, blistering rash that typically appears on one side of the body or face. While it isn’t life-threatening, shingles can cause significant pain and complications, especially if untreated.
Symptoms
- Pain, burning, or tingling sensation (often before rash)
- Red rash that develops into fluid-filled blisters
- Sensitivity to touch
- Itching or numbness in the affected area
- Fever, headache, or fatigue (in some cases)
- Rash typically appears in a stripe on one side of the body
Causes
- Reactivation of the varicella-zoster virus (from a previous chickenpox infection)
- Triggers include stress, aging, or weakened immune function
Risk Factors
- Age 50 and above
- Weak immune system (e.g., due to cancer, HIV, organ transplant)
- High stress levels
- Recent illness or major surgery
- Lack of prior varicella-zoster vaccination
Complications
- Postherpetic Neuralgia (PHN) – Persistent nerve pain after rash clears
- Vision loss (if shingles affects the eye)
- Skin infections
- Neurological problems (e.g., facial paralysis, hearing issues)
Prevention
- Zoster Vaccine – Recommended for people over 50 in Korea
- Managing stress and overall health
- Avoiding contact with people who haven’t had chickenpox
Treatment Options in Korea
- Antiviral medications (e.g., acyclovir, valacyclovir) – Must be started within 72 hours of rash appearance
- Pain relief – NSAIDs, corticosteroids, or nerve pain medications
- Topical creams – To reduce itch and irritation
- Hospitals in Korea like Seoul Asan Medical Center, Samsung Medical Center, and Seoul National University Hospital provide shingles treatment and vaccinations.
Shocks (Electric) in Korea
Overview
Electric shock occurs when a person comes into contact with an electrical current. It can range from mild tingling to life-threatening injuries. In Korea, electric shocks most often happen in the workplace, at construction sites, or due to household appliance accidents. Immediate medical evaluation is essential, even if injuries appear minor.
What is Electric Shock?
Electric shock is the physiological reaction caused by electric current passing through the body. The severity depends on the voltage, type of current (AC or DC), duration of exposure, and path through the body. Shocks may affect the heart, muscles, skin, and nervous system.
Symptoms
- Numbness or tingling
- Burns at entry and exit points
- Muscle spasms or pain
- Loss of consciousness
- Difficulty breathing or irregular heartbeat
- Seizures or cardiac arrest (in severe cases)
Causes
- Contact with live wires or faulty appliances
- Workplace accidents involving electrical tools
- Exposure to high-voltage lines
- Lightning strikes (rare)
Risk Factors
- Working in electrical or construction industries
- Wet environments (increases conductivity)
- Poorly maintained electrical systems
- Lack of safety equipment
Complications
- Cardiac arrest
- Respiratory failure
- Severe burns and tissue damage
- Neurological deficits
- Muscle damage and internal bleeding
- Long-term psychological trauma
Prevention
- Use of protective gear (rubber gloves, boots, etc.)
- Following electrical safety standards in home and industry
- Avoiding use of electrical appliances near water
- Regular inspection of household wiring and equipment
- Public awareness campaigns in Korea on electric safety
