Herpes -

The herpes simplex virus, also known as HSV, is an infection that causes herpes. Herpes can appear in various parts of the body, most commonly on the genitals or mouth. There are two types of the herpes simplex virus.

HSV-1 -
Also known as oral herpes, this type can cause cold sores and fever blisters around the mouth and on the face.

HSV-2 -
This type is generally responsible for genital herpes outbreaks. What causes herpes simplex? The herpes simplex virus is a contagious virus that can be passed from person to person through direct contact. Children will often contract HSV-1 from early contact with an infected adult. They then carry the virus with them for the rest of their lives.

HSV-1 -
Infection with HSV-1 can happen from general interactions such as:
eating from the same utensils
sharing lip balm
kissing
The virus spreads more quickly when an infected person is experiencing an outbreak. Anywhere from 30 to 95 percent of adults are seropositive for HSV-1, though they may never experience an outbreak. It’s also possible to get genital herpes from HSV-1 if someone who performed oral sex had cold sores during that time.

HSV-2 -
HSV-2 is contracted through forms of sexual contact with a person who has HSV-2. It is estimated that around 20 percent of sexually active adults in the United States are infected with HSV-2, according to the American Academy of Dermatology (AAD). While HSV-2 infections are spread through contact with a herpes sore, the AAD reports that most people get HSV-1 from an infected person who is asymptomatic, or does not have sores.

Who is at risk of developing herpes simplex infections?
Anyone can be infected with HSV, regardless of age. Your risk is based almost entirely on exposure to the infection.

In cases of sexually transmitted HSV, people are more at risk when they participate in risky sexual behavior without the use of protection, such as condoms. Other risk factors for HSV-2 include:
having multiple sex partners
having sex at a younger age
being female
having another sexually transmitted infection (STI)
having a weakened immune system

Herpes Zoster

What is Zoster
Shingles is an infection caused by the varicella-zoster virus, which is the same virus that causes chickenpox. Even after the chickenpox infection is over, the virus may live in your nervous system for years before reactivating as shingles. Shingles may also be referred to as herpes zoster.
This type of viral infection is characterized by a red skin rash that can cause pain and burning. Shingles usually appears as a stripe of blisters on one side of the body, typically on the torso, neck, or face. The first symptoms of shingles are usually pain and burning. The pain is usually on one side of the body and occurs in small patches. A red rash typically follows.

Rash characteristics include:
red patches
fluid-filled blisters that break easily
a rash that wraps around from the spine to the torso
a rash on the face and ears
itching

Some people experience symptoms beyond pain and rash with shingles. These symptoms may include:
a fever
chills
a headache
fatigue
muscle weakness

Rare and serious complications of shingles include:
pain or rash that involves the eye, which should be treated in order to avoid permanent eye damage
loss of hearing or intense pain in one ear, dizziness, or loss of taste on your tongue, which can be symptoms of Ramsay Hunt syndrome
bacterial infections, which you may have if your skin becomes red, swollen, and warm to the touch
