COVID-19 has been blamed for many things: canceled plans, suspiciously long “quick errands,” and the sudden popularity of owning six different thermometers. But one question keeps popping up in clinics and search bars: can COVID-19 trigger shingles?
The short answer is: COVID-19 does not directly “cause” shingles the way a match causes a flame. Shingles is caused by the varicella-zoster virus, the same virus responsible for chickenpox. After chickenpox, the virus does not pack a suitcase and leave. It hides quietly in nerve tissue, often for decades, like an uninvited houseguest who knows where you keep the snacks. When the immune system becomes less able to keep it under control, the virus can reactivate and cause shingles, also called herpes zoster.
Research suggests that COVID-19 infection may raise the risk of shingles in some people, especially adults over 50, people with weakened immune systems, and those who had more severe COVID-19. The relationship is not perfectly simple, but it is medically plausible: SARS-CoV-2 can disturb immune function, increase inflammation, and stress the body. For a dormant virus like varicella-zoster, that may be the opening it needs.
What Is Shingles?
Shingles is a painful, blistering rash that usually appears on one side of the body or face. It often follows the path of a nerve, which is why the rash may look like a stripe, band, or patch rather than a random sprinkling of spots. Before the rash appears, many people notice burning, tingling, itching, or stabbing pain in one area. Then come fluid-filled blisters that eventually crust over.
Common shingles symptoms include:
- Pain, burning, or tingling on one side of the body
- A red rash that develops into blisters
- Skin sensitivity, sometimes so intense that clothing feels rude
- Fatigue, headache, fever, or chills
- Itching or numbness in the affected area
Most shingles cases heal within a few weeks, but the condition can cause complications. The best-known complication is postherpetic neuralgia, or PHN, a long-lasting nerve pain that can remain after the rash disappears. Shingles near the eye can be especially serious because it may threaten vision. That is why a shingles rash on the face, forehead, nose, or around the eye deserves urgent medical attention.
How COVID-19 May Be Connected to Shingles
The immune system keeps dormant varicella-zoster virus under control mainly through cell-mediated immunity, especially T-cell activity. Think of T cells as the quiet security team patrolling the building. They do not make a big speech. They just keep trouble from walking through the front door wearing sunglasses.
COVID-19 can affect immune function in several ways. In some people, especially those with moderate to severe illness, SARS-CoV-2 infection has been associated with lymphopenia, immune dysregulation, and intense inflammation. Lymphopenia means a lower level of certain white blood cells, including lymphocytes that help control viral infections. When immune surveillance becomes temporarily weakened or distracted, dormant viruses may have a chance to reactivate.
This does not mean everyone who gets COVID-19 will develop shingles. Most people will not. It also does not mean shingles after COVID-19 proves that COVID caused it. Timing can be tricky. Shingles is common on its own, especially with age. But large observational studies and reviews have found an association between COVID-19 infection and a higher risk of herpes zoster, particularly in older adults and people with severe infection.
COVID-19 Infection vs. COVID-19 Vaccination: What Does the Evidence Suggest?
One of the most important distinctions is between COVID-19 infection and COVID-19 vaccination. Reports of shingles after COVID-19 vaccination have appeared in medical literature, but case reports alone cannot prove cause and effect. When millions of people are vaccinated, some will naturally develop shingles afterward by coincidence, because shingles already occurs frequently in the general population.
The stronger and more consistent signal appears to be with COVID-19 infection itself. A large study of adults aged 50 and older found that people diagnosed with COVID-19 had a higher risk of developing shingles compared with those without COVID-19. Other research has suggested the risk may be greater after severe COVID-19. A 2024 systematic review and meta-analysis also concluded that COVID-19 infection was associated with increased herpes zoster risk, while COVID-19 vaccination did not show the same clear increase.
In plain English: getting COVID-19 seems more likely to disturb the immune system in a way that could invite shingles than getting vaccinated against COVID-19. Vaccination may cause temporary immune activation, and some people do report symptoms afterward, but the broader evidence does not support the idea that COVID-19 vaccines are a major driver of shingles.
Who Has the Highest Risk?
Anyone who has had chickenpox can develop shingles later in life. However, risk is not evenly distributed. Some people are more likely to experience varicella-zoster reactivation, whether or not COVID-19 is involved.
Adults Over 50
Age is one of the biggest shingles risk factors. As people get older, immune protection against varicella-zoster tends to decline. This is why shingles becomes more common after age 50 and why vaccination is recommended for adults in this age group.
People With Weakened Immune Systems
People with cancer, HIV, autoimmune disease, organ transplants, or immune-suppressing medications may face higher shingles risk. This includes people taking certain steroids, biologic drugs, chemotherapy, or other treatments that reduce immune activity.
People Recovering From Severe Illness
Any serious infection can stress the body. COVID-19 is no exception. Hospitalization, high fever, poor sleep, inflammation, and prolonged recovery can all create conditions where the immune system is busy juggling flaming bowling pins. Dormant viruses may take advantage.
People Under Heavy Stress
Stress alone does not guarantee shingles, but chronic stress can affect immune function. During the pandemic, many people experienced illness, grief, isolation, financial strain, and anxiety. That emotional pressure may have contributed indirectly to shingles risk for some individuals.
What Shingles After COVID-19 Might Look Like
Shingles after COVID-19 looks like shingles from any other trigger. It usually begins with localized pain, tingling, or burning before a rash appears. The rash typically stays on one side of the body and may wrap around the torso, appear on the neck, or affect the face.
For example, a 58-year-old recovering from COVID-19 might first feel a sharp, sunburn-like pain along one side of the ribs. A day or two later, small blisters appear in a band. Another person might feel itching and sensitivity near the forehead, followed by a rash close to the eye. In both cases, the key move is not to wait and see whether the rash writes a formal announcement. Call a healthcare professional quickly.
Antiviral treatment works best when started early, ideally within 72 hours of rash onset. Common antiviral medicines include acyclovir, valacyclovir, and famciclovir. These medications can shorten the illness, reduce severity, and lower the risk of long-term nerve pain.
Is Shingles Contagious?
Shingles itself is not passed from person to person as shingles. However, the varicella-zoster virus can spread from the fluid in shingles blisters to someone who has never had chickenpox or the chickenpox vaccine. That person could develop chickenpox, not shingles.
If you have active shingles, cover the rash, avoid scratching, wash your hands often, and avoid close contact with newborns, pregnant people who are not immune to chickenpox, and people with weakened immune systems until the blisters have crusted over.
Can You Prevent Shingles After COVID-19?
You cannot control every immune system curveball, but you can reduce risk. The most effective prevention tool is the shingles vaccine, Shingrix. In the United States, Shingrix is recommended for adults aged 50 and older and for adults aged 19 and older who are or will be immunocompromised because of disease or treatment.
Shingrix is given as a two-dose series. For most adults, the second dose is given two to six months after the first. For some immunocompromised adults, healthcare professionals may recommend a shorter interval. The vaccine is not used to treat an active shingles outbreak, so if you currently have shingles, vaccination is usually delayed until the acute illness has resolved.
CDC guidance allows Shingrix to be given at the same visit as other adult vaccines, including COVID-19 vaccines, using different injection sites. Some people may prefer to space vaccines out because both can cause temporary side effects such as fatigue, arm soreness, fever, chills, or muscle aches. That is a comfort decision to discuss with a clinician, not a sign that the vaccines are fighting in the parking lot.
When to Call a Doctor
Call a healthcare professional promptly if you suspect shingles, especially if the rash is near your eye, you are over 50, you have a weakened immune system, or the pain is severe. Early treatment matters.
Seek urgent care if you notice:
- Rash or pain near the eye or forehead
- Facial weakness, hearing changes, or dizziness
- Widespread rash or rash on both sides of the body
- High fever, confusion, or severe headache
- Symptoms in someone who is immunocompromised
Shingles is usually manageable, but it is not a condition to ignore while you conduct a full internet investigation in pajamas. A short call can prevent a long problem.
Living Through the COVID-19 and Shingles Overlap: Real-World Experiences
People who develop shingles after COVID-19 often describe the experience as confusing at first. COVID symptoms may be fading, energy may be slowly returning, and then a strange pain appears on one side of the body. At first, it may feel like a pulled muscle, a patch of sunburn, or a bruise that nobody remembers earning. Then the rash arrives, and suddenly the mystery becomes less charming.
One common experience is delayed recognition. Someone may think the pain under the ribs is from coughing during COVID-19. Another person may assume shoulder blade pain is from sleeping awkwardly during isolation. A person with facial tingling may blame sinus pressure. Shingles is sneaky because pain can show up before the rash. By the time blisters appear, the treatment clock is already ticking.
Another experience is frustration. Many people expect recovery from COVID-19 to be linear: get sick, rest, improve, return to normal life. Shingles can interrupt that plan with the grace of a raccoon falling through a ceiling. The fatigue of COVID-19 plus the nerve pain of shingles can make ordinary tasks feel dramatic. Wearing a shirt may hurt. Taking a shower may feel like negotiating with tiny lightning bolts. Sleep can become difficult, which then makes recovery feel even slower.
Some people also feel anxious about what shingles means. They may wonder, “Is my immune system broken?” Usually, shingles does not mean the immune system has failed completely. It means varicella-zoster found a moment of opportunity. Still, shingles can be a useful reminder to review overall health: vaccination status, chronic conditions, sleep, stress, nutrition, and medications that may affect immunity.
For caregivers, the experience can be surprising too. A family member recovering from COVID-19 may suddenly need help with pharmacy runs, dressing changes, or pain management. The rash may look alarming, but practical steps help: keep the rash clean and covered, avoid direct contact with blister fluid, use medications as prescribed, and watch for warning signs such as eye involvement or spreading rash.
People who recover often say they wish they had called the doctor sooner. That is the biggest practical lesson. Shingles treatment is time-sensitive. Waiting a week to “see what happens” may allow the virus to do more nerve irritation than necessary. Early antiviral care is not magic, but it can make a meaningful difference.
The second lesson is prevention. Adults who are eligible for Shingrix should ask about it, even if they already had shingles before. A previous shingles episode does not guarantee lifetime protection. The immune system is impressive, but it is not a steel vault with a dragon guarding the entrance.
The third lesson is balance. The COVID-19 and shingles connection is real enough to take seriously, but not so dramatic that people should panic. Most people with COVID-19 will not get shingles. Most shingles cases can be treated. And prevention tools exist. The smartest response is not fear; it is awareness, quick action, and a good conversation with a healthcare professional.
Conclusion
The connection between COVID-19 and shingles comes down to immune stress. Shingles is caused by reactivation of the varicella-zoster virus, not by COVID-19 itself. However, COVID-19 infection may create conditions that make reactivation more likely, particularly in older adults, immunocompromised people, and those with severe illness.
The good news is that shingles is recognizable, treatable, and often preventable. If you develop one-sided burning pain, tingling, or a blistering rash after COVID-19, contact a healthcare professional quickly. If you are eligible for the shingles vaccine, ask about Shingrix. Your future nerves may send you a thank-you card, or at least stop yelling.
