What is the most common complication of varicella?
Perhaps the most serious complication of varicella is viral pneumonia, which primarily occurs in older children and adults. Respiratory symptoms usually appear 3-4 days after the rash. The pneumonia may be unresponsive to antiviral therapy and may lead to death.
Why is varicella more severe in adults?
The illness is often more severe in adults compared to children. Most people who have had chickenpox will be immune to the disease for the rest of their lives. However, the virus remains inactive in nerve tissue and may reactivate later in life causing shingles. Very rarely, a second case of chickenpox does happen.
What are the complications of varicella?
Serious complications from chickenpox include: Bacterial infections of the skin and soft tissues in children, including Group A streptococcal infections. Infection of the lungs (pneumonia) Infection or swelling of the brain (encephalitis, cerebellar ataxia)
Can babies give chicken pox to adults?

What can chickenpox lead to in adults?

Is chickenpox harmful to adults?
Chickenpox can cause serious problems. There is a higher risk of severe complications for newborns, adults, and those with weakened immune systems. Pneumonia occurs in about one in 400 adults with chickenpox, leading to coughing and breathing difficulties. It very rarely happens in young children.
Can you get shingles from chickenpox exposure?
Only people with previous exposure to VZV can develop shingles. While shingles is less contagious than chickenpox, people can still spread the virus.
Is varicella life threatening?
Protects your child from chickenpox (varicella), a potentially serious and even deadly disease.
Can adults get shingles from a child with chickenpox?

What do adults get instead of chickenpox?
Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. Anyone who’s had chickenpox may develop shingles. After you recover from chickenpox, the virus enters your nervous system and lies dormant for years.
What is the pathophysiology of neonatal varicella?
Neonatal varicella is mostly caused by maternal chickenpox acquired during the last 3 weeks of pregnancy. Transplacentally transmitted infections occur in the first 10 to 12 days of life, whereas chickenpox after that time is most likely acquired by postnatal infection.
What are the complications of varicella-zoster virus infection in children?
Infrequent complications: Thrombocytopenia, hemorrhagic varicella, purpura fulminans, glomerulonephritis, myocarditis, arthritis, orchitis, uveitis, iritis, and clinical hepatitis. Have a higher risk of complications than normal children.
What are the complications of chickenpox (varicella)?
People on chemotherapy, immunosuppressive medications, or long-term use of steroids. Serious complications from chickenpox include: Bacterial infections of the skin and soft tissues in children, including Group A streptococcal infections
What is the prognosis of congenital varicella infection during pregnancy?
Congenital varicella will be unfortunately fatal in roughly 30% of the infected babies during the first month of life and the risk of embryopathy following congenital varicella is about 2% in survivors.14Whether maternal varicella infection in the first 20 weeks of pregnancy increases the risk of miscarriage remains controversial6 14 15(table 1).
