(George Curry Media) – Almost everyone gets chickenpox by adulthood. In the United States, chickenpox affects about 4 million persons per year, mostly children. In temperate climates, most cases occur in the late winter and spring.

Although most people think that chickenpox is always a mild disease, deaths from chickenpox continue to occur in the United States. Although most people recover from chickenpox uneventfully or with a few minor scars, a small percentage suffers more serious complications. Those at highest risk for complications are newborns, persons with weakened immune systems and adults. Although adults make up fewer than 5 percent of chickenpox cases in the United States, they account for half of the deaths from the disease.

Chickenpox (varicella) rarely causes complications, but it is not always harmless. It can cause hospitalization and, in rare cases, death. Fortunately, since the introduction of the vaccine in 1995, hospitalizations have declined by nearly 90 percent, and there have been few fatal cases of chickenpox.

In most cases, people can treat chicken pox at home, as it works its way through the body in about a week. According to the Mayo Clinic, the following physical signs indicate that you should go to the doctor: Fever lasting longer than four days or exceeding 102 degrees; Fahrenheit; rash spreads to your eyeballs; rash appears infected; dizziness; tremors; stiff neck; and increased vomiting or coughing.

Adults have the greatest risk for dying from chickenpox, with infants having the next highest risk. Males (both boys and men) have a higher risk for a severe case of chickenpox than females.

Chickenpox is typically a benign, self-limited disease, but serious complications can arise. About 14,000 people are hospitalized because of chicken pox and approximately 100 people die of chickenpox every year. The risk of complications is highest in people with compromised immune systems, newborns and adults.

The most common complications of chickenpox are skin infections and pneumonia. Other complications are encephalitis (inflammation of the brain) and hepatitis. Chickenpox can also lead to severe problems in pregnant women, causing stillbirths, birth defects, or infection of the newborn during childbirth.

Chickenpox, also known as varicella, is a very contagious disease caused by the varicella-zoster virus. Infected people spread it easily through the air when they sneeze or cough. The disease also spreads through contact with an infected person’s chickenpox blisters. Because chickenpox is very contagious, it is possible for people who have never had chickenpox nor been vaccinated against it to become infected just by being in a room with someone who has the disease. However, transient exposure is not likely to result in infection.

Early symptoms may include body aches, fever, fatigue and irritability. A rash then appears and develops into as many as 250-500 itchy blisters over the entire body that usually last for five to seven days and heal with scabs. Symptoms appear between 10 and 21 days after exposure to the varicella-zoster virus. Persons who were vaccinated against chickenpox may sometimes develop chickenpox, but it is usually mild, with approximately 50 or fewer red bumps that rarely evolve to blisters.

Another common illness is shingles, or herpes zoster, a common illness that strikes about 1 million Americans each year, about half of whom are 60 years of age and older. Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. When people are first infected with the varicella-zoster virus, usually as children, they get chickenpox. Years or decades later, the virus can reactivate and cause shingles. Anyone who has had chickenpox is at risk of shingles. Shingles is associated with normal aging and with anything that weakens the immune system such as certain medications, cancers or infections, but it can also occur in healthy children and younger persons.

Shingles occurs in about 20 percent of people who have had chickenpox. The older you are, the higher the risk for complications from either chickenpox or shingles. Adults who smoke are at particularly higher risk for pneumonia from shingles.

With shingles, a painful, blistering rash tends to occur on one side of the body, usually on the trunk or face. There may be pain, numbness or tingling of the area two to four days before the rash appears. Pain or numbness usually resolves within weeks, but it can sometimes persist for much longer. Damage can occur to the eyes or other organs if they are involved. One of the most serious long-term consequences of shingles is post-herpetic neuralgia, a condition where pain persists after the rash has resolved. PHN pain can be very difficult to treat and it can diminish quality of life and functioning to a degree comparable to congestive heart failure, heart attack, type 2 diabetes and major depression.
