Severe back pain Vomiting, possibly A few days later, flat, red spots appear first on your face, hands and forearms, and later on your trunk. Within a day or two, many of these lesions turn into small blisters filled with clear fluid, which then turns into pus.
Smallpox is a contagious and sometimes fatal disease caused by two related viruses: Variola minor is less common and causes a milder form of smallpox that is usually not fatal. Smallpox eradication was one of the greatest successes of modern public health.
Through a sophisticated global vaccination campaign, the World Health Organization officially declared in that smallpox had been eliminated worldwide. The last known case of smallpox in the United States occurred inand the last case of naturally occurring smallpox was reported in in Somalia.
Today, the smallpox virus is known to exist only in secured laboratory stockpiles in the United States and Russia. However, it is theorized that other countries may have possession of the virus as well.
For this reason, there is some concern that terrorists may have access to the virus, which could be used as a bioterrorism agent. Because smallpox has been eradicated, any human smallpox infection would be evidence of bioterrorism.
For these reasons, the Centers for Disease Contol and Prevention have developed a response plan for possible smallpox outbreaks, with detailed instructions on how to mobilize appropriate personnel and vaccines.
Smallpox is usually spread through direct and fairly prolonged contact with an infected person, particularly with face-to-face contact. It is typically spread among people who share living quarters.
This is probably because patients with smallpox are severely ill in the period when they are most infectious, and so they are unlikely to have contact with many people outside their homes. Smallpox also can be acquired from infected bedding and clothes.
Rarely, smallpox is spread through the air of enclosed settings such as buildings, buses and trains. Symptoms A case of smallpox passes through six stages.
Incubation of the disease averages 12 to 14 days. During this stage, the newly infected person may feel fine or have very mild symptoms that mimic the early stages of a cold or flu and is not contagious.
Initial symptoms arise over the next two to four days and include fever to degrees Fahrenheithead and body aches, and generally feeling very sick.
Although patients may be contagious at this stage, the person typically becomes contagious during the rash stages. Early rash lasts about four days. Typically, a rash first appears as red spots in the mouth that turn to sores, and then spread to the mouth and throat.
The sores then break open to spread the virus in the mouth and throat. At the same time, a rash appears on the skin of the face and spreads to the arms, hands, legs and feet.
Within 24 hours, the rash spreads all over the body. By the third day, the rash changes into raised bumps, and, a day later, the bumps fill with a thick fluid. Often there is a depression in the middle of each bump.
Next, the rash enters the second stage, called pustular rash, in which the bumps become pustules, bumps that feel like a hard, round ball is inside the skin. The pustules develop into scabs, and most bumps scab over within two weeks after the early rash appeared.
Finally, the scabs fall off, often leaving a pitted scar. Most scabs are gone by three weeks after the rash appears.Smallpox - an easy to understand guide covering causes, diagnosis, symptoms, treatment and prevention plus additional in depth medical information.

Learn about treatment, . Smallpox is not considered an immediate health threat, but preparations for epidemic re-emergence have been issued by the CDC (Centers for Disease Control and Prevention) to governments around the world to take note of so as to better handle situations should a biological attack occur.
Smallpox is a disease caused by the variola virus. Symptoms and signs include a characteristic rash and high fever.

A person with smallpox goes through several stages as the disease progresses. Each stage has its own signs and symptoms. The incubation period is the length of time the virus is in a person’s body before they look or feel sick. During this period, a person usually has no symptoms and may feel fine.
This led to consider that smallpox could be used as a biological warfare yunusemremert.com is no treatment or cure for smallpox. A vaccine can prevent smallpox, but the risk of side effects from the vaccine is too high to justify the routine vaccination for persons of low risk of exposure by pox viruses currently.
