Reactivation of 2 Genetically Distinct Varicella-Zoster Viruses in the Same Individual

Covid-19 Vaccination and Reactivation of Varicella Zoster Virus

Introduction: After COVID-19 pandemic in 2020 that mostly affects upper respiratory tract, the scientists investigated an effective vaccine against the virus. As the vaccination of general population started some patients were visited with varicella zoster virus activation following the COVID vaccine.

Neurological complications of varicella zoster virus reactivation.

PURPOSE OF REVIEW Varicella zoster virus (VZV) reactivation results in zoster, which may be complicated by postherpetic neuralgia, myelitis, meningoencephalitis, and VZV vasculopathy. This review highlights the clinical features, laboratory abnormalities, imaging changes, and optimal treatment of each of those conditions. Because all of these neurological disorders produced by VZV reactivation ...

Gastric ulcers due to varicella-zoster reactivation.

We report on an 18-year-old man with common variable immunodeficiency presenting with abdominal pain and vomiting due to gastric ulcers caused by reactivation of varicella-zoster virus (VZV). Endoscopy revealed multiple ulcers in the gastric antrum. Fever and rash developed the next day. Skin biopsy showed multinucleated cells with intranuclear inclusions highly suggestive of VZV infection, and...

Stress-induced subclinical reactivation of varicella zoster virus in astronauts.

Varicella zoster virus (VZV) becomes latent in human ganglia after primary infection. VZV reactivation occurs primarily in elderly individuals, organ transplant recipients, and patients with cancer and AIDS, correlating with a specific decline in cell-mediated immunity to the virus. VZV can also reactivate after surgical stress. The unexpected occurrence of thoracic zoster 2 days before space f...
