Overview

 Chickenpox is a common disease usually associated with childhood known for an outbreak of "red bumps" throughout the entire body.  By the adult years more than 95% of  Americans have had  Chickenpox.  Approximately four million people get this disease each year.The disease is caused by the varicella-zoster virus (VZV) and can be diagnosed through a medical examination. Transmission occurs from person-to-person, by direct contact, or through the air . The Chickenpox disease can be considered dangerous to infants and adults but if treated properly it is not a treat to longterm health. Chickenpox is contagious one to two days before the appearance of the rash until the blisters have dried and become scabs. Once infected, chickenpox may take up to 10 to 21 days to develop. It is important to contact a doctor, when the disease is recognized or suspected, so that the proper treatment can begin.    

Symptoms

 Chickpox symptoms are usually mild among children,  but may be life threatening to infants, adults, and those that have an impaired immune system.  Many of the following symptoms are common among those that are infected with chickenpox but symptoms very from person to person.  
 

                                             Chickenpox               

 

Treatment for chickenpox may include:


Keep in mind...do not scratch the blisters because it could lead to secondary bacterial infections. Keep fingernails short to decrease the likelihood of scratching.


Classification

Classification for Chickenpox depends upon the serverity of the disease.  Specific treatment for chickenpox will be determined by your physician based on:



Chain of  Infection

chain of infection

If the chain of Infection is broken at any time the disease is no longer in an active state. 

Examples:

Causative Agent- VZV virus

Reservoir- Contact with people

Portal of Exit- Sneezing

Mode of Transmission- Airborne

Portal of Entry- Newly infected mouth

Susceptible Host- A person that contracted the disease  

Prevention

The best way to prevent Chickenpox is discontinue the time spent with a host to the disease or break the chain of infection another way.Most people who have had chickenpox will be immune to the disease for the remainder of their lives but, the virus remains dormant in nerve tissue and may reactivate, resulting in herpes zoster (shingles) later in life. Sometimes a secondary case of chickenpox does occur, however, it is usually not as serious. Blood tests can confirm immunity to chickenpox in people who are unsure if they have had the disease.

Eradication 

The varicella vaccine is a shot that can prevent chickenpox.  Up to 90% of people who receive the vaccine will not get chickenpox, thus breaking the chain of infection. For those that still get chickenpox, after receiving the vaccine, they receive a much milder form of the disease.  The chickenpox vaccine is not required, as some of the vaccines are, however it is a good idea to vaccinate children between the ages of 12-18months to reduce the risk of chickenpox.
