Signs and Symptoms of Chicken Pox Chickenpox is a highly contagious disease that spreads from person to person by direct contact or through the air from an infected per…son's coughing or sneezing. Touching the fluid from a chickenpox blister can also spread the disease. A person with chickenpox is contagious from 1-2 days before the rash appears until all blisters have formed scabs. This may take 5-10 days. It takes from 10-21 days after contact with an infected person for someone to develop chickenpox. The chickenpox lesions (blisters) start as a 2-4 mm red papule which develops an irregular outline (rose petal). A thin-walled, clear vesicle (dew drop) develops on top of the area of redness. This "dew drop on a rose petal" lesion is very characteristic for chickenpox. After about 8-12 hours the fluid in the vesicle gets cloudy and the vesicle breaks leaving a crust. The fluid is highly contagious, but once the lesion crusts over, it is not considered contagious. The crust usually falls off after 7 days sometimes leaving a crater-like scar. Although one lesion goes through this complete cycle in about 7 days, another hallmark of chickenpox is the fact that new lesions crop up every day for several days. Therefore, it may take about a week until new lesions stop appearing and existing lesions crust over. Children are not to be sent back to school until all lesions have crusted over. Second infections with chickenpox occur in immunocompetent individuals, but are uncommon. Such second infections are rarely severe. A soundly-based conjecture being carefully assessed in countries with low prevalence of chickenpox due to immunisation, low birth rates, and increased separation is that immunity has been reinforced by subclinical challenges and this is now less common. This is more dangerous with shingles. There have been reported cases of repeat infections. Chickenpox is highly contagious and is spread through the air when infected people cough or sneeze, or through physical contact with fluid from lesions on the skin. Zoster, also known as shingles, is a reactivation of chickenpox and may also be a source of the virus for susceptible children and adults. It is not necessary to have physical contact with the infected person for the disease to spread. Those infected can spread chickenpox before they know they have the disease - even before any rash develops. In fact, people with chickenpox can infect others from about 2 days before the rash develops until all the sores have crusted over, usually 4-5 days after the rash starts. 1. http://en.wikipedia.org/wiki/Chicken_pox Very itchy, fever, not very hungry and very uncountable. Tiredness, loss of appetite, fever, nausea, headache. The most obvious symptom are the pox marks on the skin.
Chickenpox has been around for thousands of years, and it's not possible to know how the first case occurred.
Yes, you can get chickenpox. With increasing rates of immunization, the chances are lower, but it can still happen if you are not immunized or haven't been infected in the pas…t.
The virus which causes chicken pox, varicella zoster, is passed on through close contact with an individual who has ongoing chickenpox. Touching the spots or pox when they wee…p will pass the virus on. Chickenpox is also spread in fine droplets of moisture, which contain the virus. The droplets are produced when the infected person coughs or sneezes, another person then inhales these droplets and may become infected. See the related links for more complete information. Chickenpox is a highly contagious viral disease that causes hundreds of itchy, fluid-filled blisters on the skin that burst and form crusts. The disease usually affects children, though adults may become infected as well. It is transmitted by direct contact with a rash or through contaminated droplets in air or moisture, usually spread by coughing or sneezing. The varicella-zoster virus (VZV) responsible for chickenpox is one of eight herpes viruses known to infect humans and is found throughout the world. Varicella is transfered through touching the blisters of an infected individual.
Chickenpox was first identified by the Persian physician, Muhammad ibn Zakariya ar-Razi 865-925. The chickenpox virus was originally thought to be related to the much more da…ngerous smallpox virus, but in the early 1900s it was realized that it is not at all like smallpox. Chickenpox, or varicella, is a member of the herpesvirus family of virues. That means it is related to Epstein-Barr virus which causes mono, and herpesvirus which causes fever blisters and other things. As far as I can tell (I'm looking at an introduction to the history of virology from 1978) the guys who first described the chickenpox virus were E. Paschen, 1919; EE Tyzzer, 1906; von Bokay 1909. In 1954 Weller discovered that chickenpox and shingles are caused by the same virus.
The vaccine for chicken pox came out in the year 1995, because many people were dying from this disease. But only adults were dying from it and they say very few kids died fro…m it. 1995 February 30, 19990.543. If you are wondering why this is a dog that can lick oysters with its finger then pumpkins are green and have did you know that the tree in my backyard is purple and french fries taste good with grass cakes. The first vaccine was given in 1975. 1995 in the United States
1. Is that you keep getting red dots all over you body 2. Is that you have fever 3. If you have itchiness
The best-known signs of chickenpox are: A red, itchy rash that initially may look like insect bitesSmall, liquid-filled blisters that break open and crust over The chickenpox …rash occurs in three stages. First, there are raised pink or red bumps (papules). These bumps will turn into fluid-filled blisters (vesicles). And, finally, the vesicles will crust over and scab. It's possible that all three of these stages may occur at once. The rash may be preceded by or accompanied by:FeverAbdominal pain or loss of appetiteMild headacheGeneral feeling of unease and discomfort (malaise) or irritabilityA dry coughHeadache Common sites for the rash include the face, scalp, chest and back. The rash can also spread across your entire body, even into your throat, eyes and vagina. New spots continue to appear for several days. In healthy children, the disease is generally mild.
Chickenpox lesions usually show up first on the chest, head, and back. Then it spreads over the body.
Chickenpox was invented in Japan in 1974.
Fever is generally the first symptoms with the rash starting on the face a day or two later. Early symptoms - often preceding the rash symptomsAchingTirednessHeadacheFeverSor…e throatMalaise Little red bumps Symptoms are usually more severe in adults than in children. Expect to have a few uncomfortable days.
Signs of infection include leakage of pus from the blisters or excessive redness, warmth, tenderness, or swelling around the blisters.
Chickenpox has been around for thousands of years, and it's not possible to know when and where the first case occurred.

Yes, the skin lesions of chickenpox are the most specific sign of the infection.
Chicken pox vaccine was approved for in the United States in 1995. the varicella vaccine (Varivax) was released for use in 1995
