Herpes zoster can take a toll on the entire body.
Shingles (herpes zoster, or HZ) is most commonly associated with a painful, blistering rash in a band across the skin on 1 side of the body that lasts 2 to 4 weeks. However, depending on where it erupts and other variables, HZ can also cause hearing, vision, and balance problems; secondary skin infections; post-shingles heart attack or stroke; and serious complications like postherpetic neuralgia and postherpetic itch.
When shingles occurs on the face, for example, early symptoms may include headache, general malaise, or fever. “When shingles involves branches of the trigeminal nerve, which innervates the region around the eye, eyelid swelling, conjunctivitis, ocular pain, light sensitivity, or visual changes may result,” explained Sarina B. Elmariah, MD, PhD, a board certified dermatologist at Massachusetts General Hospital.
Some forms of shingles are identified by their location on the body and have their own symptoms and complications. In cases of herpes zoster ophthalmicus, which affects the eye, ocular pain, redness, and permanent visual changes or vision loss are all possible outcomes. Herpes zoster oticus (HZO), also known as Ramsay Hunt syndrome, is a shingles outbreak that affects facial nerves near the ear. In addition to blisters inside or around the outer ear, HZO can cause ear pain, altered hearing, facial paralysis on the affected side, tinnitus, vertigo, and hearing loss. Enteric shingles occur internally along the digestive track and can affect the esophagus, stomach, and large and small intestines. It causes unexplained and chronic abdominal pain, and has been found in patients with inflammatory bowel disease and Crohn disease.
Dr Elmariah said that early warning signs that a case of shingles may be more complicated than usual include taste or hearing changes, severe headaches, sensory loss, muscle weakness, and bladder or bowel dysfunction, which may signify encephalitis, meningitis, or myelitis. She advises her patients who experience shingles symptoms to seek care immediately from their health care provider and to start anti-viral therapy as soon as possible. She also encourages them to cover any blisters, erosions, or open skin to limit the spread of the virus.
“It is also important for individuals with shingles to distance themselves from immunocompromised individuals, pregnant women, or those who have not been vaccinated against chickenpox, as these populations can face serious complications if they were to become infected,” she said.
Finally, Dr Elmariah highly recommends the shingles vaccine Shingrix to her eligible patients, including immunocompetent individuals who are 50 and older and immunocompromised individuals under 50 years old. “Shingrix not only reduces the risk of experiencing the shingles rash, but it also limits the severity of disease and reduces the risk of postherpetic neuralgia even in those who do develop the rash,” she noted.
The CDC recommends 2 doses of Shingrix separated by 2 to 6 months for immunocompetent adults age 50 years and older. For individuals who previously received Zostavax, it advises a wait of at least 8 weeks before administering Shingrix. Individuals who are getting other routinely recommended adult vaccines in the same physician’s visit, including influenza and pneumococcal vaccines, can receive Shingrix at the same time.1
