Essay On Varicella
Varicella zoster virus is a double stranded icosahedral, nucleocapsid DNA molecule, with a lipid envelope enclosing it. Varicella zoster virus develops a latent infection in the neurons of the sensory ganglia. Primary infection causes varicella (chickenpox), and reactivation of the virus causes a latent infection known as herpes zoster (shingles). Varicella is more common in children. Infection in adults is more severe and can lead to interstitial pneumonia. It is also more frequent in immunocompromised individuals. Varicella is a disease characterized by scattered vesicular lesions, fever, and viremia. Headaches, malaise, and loss of appetite are also common. Herpes zoster is characterized by a localized, painful, vesicular rash on the skin

It is administered intravenously to newborns that were exposed to the virus after birth, and to patients at risk for the virus or have evidence of the virus. It also helps prevent reactivation of the virus in immunosuppressed individuals. A live attenuated varicella vaccine known as Oka or Merck strain is now available for routine vaccination during childhood vaccination. Varivax® is the single-antigen varicella vaccine. Two doses of the chickenpox vaccine is given to children, adolescents and adults for protection. The first dose for children is given at 12-15 months and the second dose is given at 4-6 years old. If a hygienist or any other healthcare provider is suffering from varicella zoster virus, they should not be providing care to others because it is highly contagious and can easily be transmitted via contact or airborne. Nonsocomial transmission of the disease can easily be spread to other healthcare providers, patients without immunity like pregnant women, infants, and immunocompromised individuals. According to the CDC, if symptoms occur in a healthcare provider, they should be immediately removed from patient care areas and receive antiviral
