Varicella is a common childhood disease, but there are some risks of complications. The virus can cause skin infections, encephalitis, and pneumonia. It is dangerous for pregnant women and people with certain immune conditions. A pregnant woman who contracts varicella may give birth to a baby with congenital varicella syndrome or neonatal hemorrhage.
Varicella-zoster immune globulin
VZV immunoglobulin is a medication for immunosuppression patients to boost their immune systems. It helps shorten the course of the cutaneous disease and may protect the patient from its spread. It may also help prevent the disease from coming back.
Human immunoglobulins are made by plasma cells. They are composed of proteins that recognize a variety of antigenic determinants. When human immunoglobulins are lyophilized, they are filled with antibodies against the varicella-zoster virus (VZV). These antibodies attach to the proteins of the varicella virus and protect the body from the disease.
Unvaccinated older children
The occurrence of breakthrough varicella after varicella vaccination is rare. However, the disease can occur even 42 days after the first dose. A breakout can lead to inflammation of the blood and brain membranes, joint infections, or shingles. In addition, if the disease is not treated soon after, it can reactivate the virus.
The disease is generally self-limiting, but it can cause serious complications or even death in rare cases. Since the introduction of the varicella vaccine in 1995, the incidence of the disease, hospitalizations, and deaths associated with the disease has dropped significantly in the United States. However, in 2009, an unvaccinated 15-year-old girl from Ohio died after contracting the disease. According to the Ohio Department of Health, the disease was the underlying cause of her death.
Although varicella vaccination is recommended for children, unvaccinated adults risk developing the disease. The vaccine for varicella can prevent the development of severe disease. It is essential for adults who live with or care for children, are non-pregnant, and travel internationally.
Varicella vaccines can be administered at the same time as other vaccines. However, a person should delay receiving the varicella vaccine for at least 28 days after receiving other vaccines, including the MMR vaccine and the intranasal live attenuated influenza vaccine. Although the varicella vaccine is generally well tolerated, rare cases of severe adverse reactions are reported. Contact your healthcare provider immediately if you suspect you have had a severe reaction to the vaccine.
The Varicella-zoster virus (also known as human herpesvirus three or human alphaherpesvirus 3) is responsible for chickenpox in children and shingles in adults. Although it is not common in children, the virus can cause severe skin diseases. In addition, this virus is species specific to humans, so prevention and treatment are essential.
Healthy children often develop a mild case of varicella, which manifests as an itchy rash. The illness may also be accompanied by malaise and a temperature of 102 degrees Fahrenheit for two to three days. However, infants and those with a compromised immune system may develop more severe complications, including pneumonia and kidney problems. The second case of varicella is rare among healthy individuals, and it is more common among immunocompromised individuals. Vaccination can help prevent the recurrence of varicella in healthy adults.
Varicella-zoster virus causes shingles.
Shingles are a common skin rash caused by the varicella-zoster virus, the same virus that causes chickenpox. The virus lays dormant in nerve tissues near the spinal cord and brain before re-emerging as a painful, blister-like rash. The rash is not contagious, but the virus can be spread by contact with the fluid within the blisters. People with weakened immune systems are more likely to develop shingles.
Adults can risk shingles if they’ve had chickenpox during childhood. The virus can remain dormant for decades before reactivating. In addition, aging, stress or HIV ca,n lower the immune system’s ability to fight off the virus. The virus can sometimes spread to the eyes, resulting in herpes zoster ophthalmicus. About one million cases of shingles occur each year in the U.S.
