Treatments and Cures
There is no cure for smallpox but there are treatments for the symptoms and a vaccine.
By. Nate Buckley
Areas of the world affected
Smallpox could have affected anywhere in the world but there were some main ones
A couple of the main ones include Europe and The United States
The vaccine is only available in emergencies

Incubation and cause of smallpox
By Adam Phillips
The smallpox disease is caused by the variola virus. There are two types, variola major, the more common and more deadly of the two, and variola minor. It is a member of the Orthopoxvirus Genus. It is different from other viruses in the fact that it has two protein coats to protect itself. The protein coats give it a higher chance of survival than other viruses. This virus was eradicated by the smallpox vaccine, and now exists almost exclusively in laboratories such as those of the CDC although terrorist organizations may have small quantities of the virus. It usually takes about 7 to 17 days after infection for symptoms to show. The first symptoms include Fever, malaise, vomiting, and aches. Before symptoms show the infected person is not contagious, but that changes dramatically at the emergence of the first symptom. Once the incubation period ends, the virus replicates so rapidly inside the cells that the cells begin to burst. Also once the incubation period ends the disease rapidly increases in severity.

Most weird facts about smallpox revolve around the theories that it could be used as a biological weapon. Biological warfare is a serious problem and may even be foreseeable in the future. Smallpox, or rather variola, the smallpox virus, can be stable as an aerosol, making it a possible terrorist threat, or a terrible weapon that could be used as a government or certain group pleases. Most scientists agree that full immunity from vaccination only lasts 3-5 years, so even though people took the vaccine a long time ago, they can still be infected today.

Symptoms of smallpox infection usually appear within 10 to 12 days after exposure to the virus. The symptoms of smallpox include: High fever, Fatigue, Headache, Malaise,Backache, Rash
The rash starts with flat red lesions that develop at the same rate. After a few days, the lesions become filled with pus. They begin to crust early in the second week. Scabs develop and then separate and fall off after about 3 weeks.
By Jacob Gonzales
The mortality rate, or death rate, is the number of deaths (in general, or due to a specific cause) in a population, scaled to the size of that population, per unit of time. Smallpox has a mortality rate of 30%. Variola minor, or alastrim, is a milder form of the virus with a mortality rate of 1%.
There are four other types of variola: classic, hemorrhagic, malignant, and modified. About 30% of unvaccinated people who came in contact with classic smallpox became infected.The hemorrhagic has a much higher mortality rate of 95%.
Before it was eradicated, the malignant form of smallpox affected 6% of the population but killed the most with a mortality rate of around 100%. In a vaccinated population, the modified version could affect about 15% of the population.
Summary of the History of Smallpox
- Not sure when the
- May have evolved from a rodent virus
- 68,000 to 16,000 years ago.
- More intense strains appeared 1,600 to 400 years ago, followed by a second less intense strain.
- Ramses V, of Egypt
- Died 3,000+ years ago
- His body showed examples of scarring
- Smallpox diseases have been recorded in India and China around 1000 BC.
- Theory is that Egyptian traders brought smallpox to India.
- Both Old and New Testaments do not really mention smallpox.
- 850:St. Gregory of Tours observed and recorded a outbreak of smallpox in France/Italy.
- First used
- It is possible that Arabic armies brought the disease to Europe.
- Persian physcian
The Book of Smallpox and Measles
- Good description of smallpox.
Middle Ages and Americas
- 16th century: By this time Smallpox was everywhere.
- Affected children
- Because of European exploration/colonization smallpox spread globally.
- Entered mainland America ( Mexico ) in 1520.
- Destroyed native populace.
- 1633 Plymouth, Mass.: Pilgrims brought smalpox to North America.
- Did not affect Australia all that much.
18th, 19th,and 20th Centuries
- Had become a major global endemic disease.
- Leading cause of death on Europe.
- Vaccinations become common practice in more developed countries.
- Due to
spread, it helped build immunity to
- Edward Jenner showed how cowpox could help protect humans from smallpox in 1796.
- Wealthy countries then start to design programs to vaccinate their citizens.
- Also enact laws to make people get vaccinated.
- 1900 to 1914: Smallpox largely eliminated in Northern Europe.
- 1966: Smallpox Eradication Unit formed.
- Strategy: Stop spread of smallpox, isolate reported cases, and vaccinate all who are in the vicinity of the infected.
- "Ring Vaccination"
- Last reported case was Rahima Banu, a Bangladesh girl.
- December 9, 1979: Global eradication of smallpox announced.

People Associated and Transmission of Smallpox
Small pox is highly contagious. It is most commonly spread by inhaling infected saliva. Another way is by being in direct contact with objects that have the disease on them. This is why caretakers and nurses soak objects in bleach. Ten days after the infection sets in it is contagious to someon else. Edward Jenner was the person who developed the cure and vaccine. Many people had the disease in ancient times, including King Tut.
