Covering a shingles rash: Step

The varicella-zoster virus (VZV) causes shingles, a painful rash that can occur anywhere on the body but usually develops on one side of the torso. Covering a shingles rash is key to preventing the virus from spreading.

When someone has chickenpox and recovers, the virus remains dormant in the body. Later, it can reactivate and cause shingles. This occurs in about 1 in 3 people in the United States. Most people only develop shingles once, although it can occur more often.

Shingles usually appear as a patch of blisters on one side of the torso, between the neck and pelvis. However, the rash can appear on other parts of the body. The blisters usually weep, crust over, and clear in 7–10 days, while the rash clears completely in 2–4 weeks. However, some people can develop postherpetic neuralgia, causing pain that can last for months.

Preventing the transmission of shingles is important. Direct contact with fluid from the rash can spread the virus to people who have never had chickenpox or had the vaccine. They may develop chickenpox, as opposed to shingles, directly following the exposure. However, they could also develop shingles later in life.

Shingles spreads through direct contact with fluid from the blisters of the shingles rash. The VZV virus can spread through this fluid to someone who has never had chickenpox and can trigger an infection in them. However, individuals will not develop shingles at the time of exposure. If they develop chickenpox, they are prone to developing shingles later in life.

Shingles cannot spread before the rash is present or after the rash forms a crust. The risk of spreading shingles reduces greatly after covering the rash.

A caregiver who handles clothing or rash bandages that were in contact with the rash may have exposure to VZV.

According to the American Academy of Dermatology (AAD), people need to care for their shingles rash daily. They must also cover it to prevent spreading shingles to others. To cover a rash, people can follow these steps:

Covering a shingles rash is key to preventing transmission of ZVZ. To prevent the spread of the virus, people can also avoid:

Anyone over 50 years of age or those aged 19 or older with a weakened immune system is eligible for the shingles vaccine. According to the Centers for Disease Control and Prevention (CDC), the shingles vaccination, Shingrix, is over 90% effective at preventing shingles and its complications in healthy adults. In adults with weakened immune systems, it is 68–91% effective, depending on the condition that weakened the person’s immune system.

People typically receive Shingrix in two doses 2–6 months apart, though individuals may receive a second dose sooner if they have immune system issues. Those with shingles should also get the vaccine once the rash has resolved completely to prevent future reoccurrence.

If an individual is caring for someone with shingles, the best way to avoid getting shingles is to not touch the rash or any items that come in contact with it.

They need to use gloves where possible and wash their hands thoroughly with soap and hot water after handling any garments, wound dressings, towels, or bedsheets that touch the rash.

Shingles appears as a rash on the skin’s surface, but it can also affect the nerves and be itchy, painful, and uncomfortable.

Some potential ways to relieve a shingle rash include:

The CDC also suggests using over-the-counter pain relief, such as acetaminophen, when necessary. If the pain is persistent, a person can talk with a doctor who may suggest alternative treatments.

It can take several weeks for a shingles rash to clear up. Practicing self-care may help people feel better.

The AAD recommends contacting a doctor within the first 3 days of the rash appearing. A doctor can prescribe antiviral medications that may lessen symptoms, shorten their duration, and reduce the risk of complications.

Some people can develop other health problems following shingles. People need to contact a doctor if they:

For most people, shingles clears in 7–10 days, and the rash clears completely in 2–4 weeks.

Postherpetic neuralgia (PHN) is a fairly common complication of shingles, and 10–18% of people who have shingles will develop it. PHN causes nerve pain that can be severe and interfere with daily life. It can last for months or years after the rash clears.

VZV, the same virus that causes chickenpox, causes shingles. When a person gets chickenpox and recovers, the virus lies dormant in their body. Later in life, it may reactivate and cause shingles.

The virus spreads through the fluid that seeps from the rash’s blisters. Covering the shingles rash with a sterile, clean gauze or bandage reduces the risk of a person transmitting the virus to others.

Anyone who has shingles or is in close contact with someone who has it needs to wash their hands frequently and avoid sharing towels, bedsheets, and personal hygiene products.
