Is it possible for smallpox to come back?

What is smallpox called today?

Where is smallpox kept today?

There are two WHO-designated sites where stocks of variola virus are stored and used for research: Centers for Disease Control and Prevention, Atlanta, Georgia, United States, and the Russian State Centre for Research on Virology and Biotechnology, Koltsovo, Novosibirsk Region, Russian Federation.

Is smallpox a threat today?

Smallpox has been eradicated for decades, but other, related “poxviruses” are still around and continue to pose a risk to humans, experts say. In fact, cases of human infection with viruses in the same family as the smallpox virus are appearing in growing numbers.

What was the cure for smallpox?

Can it be treated? There is no cure for smallpox, but vaccination can be used very effectively to prevent infection from developing if given during a period of up to four days after a person has been exposed to the virus. This is the strategy that was used to eradicate the disease during the 20th century.

Where did the smallpox virus come from?

Smallpox is thought to have originated in India or Egypt at least 3,000 years ago. The earliest evidence for the disease comes from the Egyptian Pharaoh Ramses V, who died in 1157 B.C. His mummified remains show telltale pockmarks on his skin.

Which lab has smallpox?

Despite these ongoing arguments, live samples of the smallpox virus are still housed at two locations. One laboratory is in Russia’s State Research Center of Virology, located in the city of Koltsovo in Siberia. The other samples are kept at the U.S. Centers for Disease Control and Prevention in Atlanta.

What is the difference between smallpox and chickenpox?

Chickenpox is the most important disease likely to be confused with smallpox. It is caused by a different virus. In smallpox, fever is present for 2 to 4 days before the rash begins, while with chickenpox, fever and rash develop at the same time.

How did Janet Parker get smallpox?

The Shooter Inquiry found that Parker was accidentally exposed to a strain of smallpox virus that had been grown in a research laboratory on the floor below her workplace at the University of Birmingham Medical School.

Who was most likely to get smallpox?

The highest smallpox infection rates were in persons 0–19 years of age, but the highest death rates were in those >45 years of age. Because of the low level of residual vaccine immunity, immunosuppression was more influential than vaccination on death and infection rates in our model.

Why is there no cure for smallpox?

No cure or treatment for smallpox exists. A vaccine can prevent smallpox, but the risk of the vaccine’s side effects is too high to justify routine vaccination for people at low risk of exposure to the smallpox virus.
