Varicella

Varicella, commonly known in the United States as chickenpox, is a highly contagious disease caused by the varicella virus. The contagious period lasts from about three days before the rash seems until all the blisters have formed scabs. Chickenpox blisters show up in waves, so after some start to crust over, a new group of spots may arise. The red, itchy rash is caused by the varicella-zoster virus, that is part of a group of viruses called herpesviruses. It spreads easily from person to person through the air and physical contact. An itchy rash of spots which appear like blisters can appear all over the body and may be companioned by flu-like symptoms.

Varicella is rarely calamitous (usually from varicella pneumonia ), with pregnant women and those with desolated immune systems being more at risk. It happens worldwide, focussing persons of all races, gender and age. However, it is greatly a childhood disease with most cases appeaing in children before 10 years of age. Varicella is usually self-limiting with low morbidity and fatality in healthy children.

Varicella affects about all children who lacks immunity. Chicken pox can occur at any time, but occurs most frequent in March, April, and May in mild climates. Once a child has had chickenpox he will usually never get it again. Very rarely, a child may have a second moderate attack of chickenpox. Chickenpox is very highly infectious. Children having varicella expose adult contacts in households, schools, and daycare centers to the risk of acute, even deadly disease.

A person is most capable to bequeath chickenpox from one to two days before the onset of rash till all lesions have crusted. After a person has chickenpox, the virus typically lives quietly in the nervous system of the body for the rest of a person's life. Diagnosis of chickenpox is generally made on the demeanor of its characteristic rash (initial red papules which excogitate into vesicles containing fluid) and that dissimilar stages of lesions are present contemporarily. Marks frequently clear away without treatment, but as the infection is very infectious, an infected child should stay home and rest until the symptoms are gone.

This involves taking acetaminophen (such as Tylenol) or ibuprofen (such as Advil) to reduce fever and discomfort and taking non-prescription oral medications or using lotions to lessen itching.
