Transcript of Chickenpox Presentation
How is the disease spread?
What Causes this
Who is most susceptible to receive Chicken Pox and does is still occur today?
How can this disease be prevented?
Chickenpox has been first discovered by Giovanni Filippo during the 1500s in Italy. In the 1600s, Richard Morton who was an english physician thought chicken pox was a milder form of small pox. Another English physician, William Heberden was the first physician to prove that chickenpox was actually different from smallpox in the 1700's. Before all of this was established. the name "pox" was given to a number of diseases which were believed to be brought on as the result of a curse. Chicken pox was thought of to attack children who were cursed by black magic.
Chicken pox is an extremely contagious infection caused by the varicella zoster virus. When the virus accesses to the body it rests and reproduces in the lymph nodes of the body for about 3 to 4 days. It then travels to the blood to infects the spleen and liver. It rests again in the nerve roots until it is operated. It may wait for incidents like stress or diminished immunity to occur before it attacks the system.
Chicken pox spreads through sneezing and coughing and contact with the production from the blisters because it is a airborne disease. A person is contagious before and during they are directed with this virus. When all the lesions have crusted over, they can no longer pass it on to somebody else. Individuals with weakened immune systems may be contagious for longer.It takes ten to twenty one days after exposure for someone to develop chickenpox. If a person vaccinated for chickenpox gets the disease they can still spread it to others and if they are vaccinated they can still get the disease.
For most people, getting chickenpox once provides immunity for life. However a few people tend to get chicken pox more than once in your life time.
Chickenpox is most common a childhood disease, with more than 90% of cases occurring in children younger than 10 years. The disease is harmless in a healthy child but can be very difficult for an elderly person to handle and even mid age. Immune systems are much stronger in a young child. Chicken Pox has scarred the skin in some cases where antibiotics are needed. Children are encouraged to try and receive the disease because it will most likely occur when you are older. If a person is pregnant, it can cause harm to the mother and the baby. It is better to get it over with when you have a healthy immune system as a child.
Soothing baths may relieve itching along with adding oatmeal and aveeno. The most common lotion used for chicken pox is Calamine lotion. This helps dry out the blisters and soothe the skin. Antihistamines may be used to control severe itching. The drowsiness may help the child sleep at night. The newer antihistamines such as loratadine, certrizine, and fexofenadine control itching but do not cause drowsiness.
Scratching increases the risk of secondary bacterial infections. All patients with chicken pox should have their nails trimmed short or even wear mittens. Acyclovir is an anti-viral drug that may be used to treat chicken pox. It shows more rapid healing and is recommended for people who have eczema, newborns, adults, and smokers.
The best way to prevent chickenpox is to get the chickenpox vaccine. Children, adolescents, and adults should have two doses of chickenpox vaccine.
Chickenpox vaccine is very safe and effective at preventing the disease. Most people who get the vaccine will not get chickenpox. If a vaccinated person does get chickenpox, it is usually mild—with fewer blisters and mild or no fever. The chickenpox vaccine prevents almost all cases of severe disease.

Shingles looks like chickenpox and is caused by the same virus. Most of the times it is only on one part of the body. Shingles is visible on people who have had chickenpox already and will not occur for years later.
