Smallpox

[Sarah]

A contagious, constitutional, febrile disease characterized bya peculiar eruption; variola. The cutaneous eruption is at first acollection of papules which become vesicles (first flat, subsequentlyumbilicated) and then pustules, and finally thick crusts which sloughafter a certain time, often leaving a pit, or scar.

[Sarah]

An acute, highly infectious, often fatal disease caused by a poxvirus and characterized by high fever and aches with subsequent widespread eruption of pimples that blister, produce pus, and form pockmarks. Also called variola.

After 9/11, there was concerns terrorists might use smallpox in an attack.

Supposedly the US holds enough vaccine for it's entire population in case there were ever an outbreak.

Smallpox is a highly contagious, very deadly disease caused by the variola virus. The disease is now considered eliminated.

There have been no cases of smallpox since 1977.
People can acquire the infection by breathing air exhaled or coughed out by an infected person.
People have a fever, headache, backache, and rash, sometimes with severe abdominal pain, and they feel very ill.
The diagnosis is confirmed when the virus is identified in a sample taken from the rash.
Vaccination within the first few days of exposure can prevent the disease or limit its severity.
Treatment involves fluids, relief of symptoms, and treatments to maintain blood pressure and help with breathing.

(See also Overview of Viral Infections.)
The smallpox virus can exist only in people—not in animals.
There are two main forms:

The severe form (variola major) is the most common and is the one of concern.
The other form (variola minor) is much less common and much less severe.

Throughout history, smallpox has killed millions of people. Over 200 years ago, a vaccine against smallpox (the first vaccine ever) was developed. The vaccine proved very effective and was given to people throughout the world. The last case of smallpox was reported in 1977. In 1980, the World Health Organization (WHO) declared the disease eliminated and recommended stopping vaccination.
Samples of the virus are kept in two high-security laboratories (one in the United States and one in Russia).
Because the vaccine’s protective effects gradually wear off, nearly all people—even those previously vaccinated—are believed to be susceptible to smallpox to various degrees. This lack of protection is a concern only because samples of the virus have been stored, and some people worry that terrorist groups could obtain the virus and release it into the population. The resulting epidemic would be devastating.
The smallpox virus spreads directly from person to person and is acquired by breathing air contaminated with droplets of moisture breathed or coughed out by an infected person. Contact with clothing or bed linens used by an infected person can also spread the disease. Smallpox usually spreads to people who have close personal contact with an infected person. Rarely, smallpox spreads through the air in an closed environment, such as a building, where someone has smallpox. A large outbreak in a school or workplace would be uncommon.
The virus survives no more than 2 days in the environment— less if temperature and humidity are high.
