Question 1

Can smallpox come back, or has it been completely eradicated?

Accepted Answer

Smallpox was declared eradicated by the World Health Organization in 1980, and no naturally occurring cases have occurred since. However, because intact virus samples are retained under strict control in two labs, smallpox remains a possible bioterrorism threat.

Question 2

Is smallpox curable, and how was it treated before eradication?

Accepted Answer

There was no cure for smallpox. Before its eradication, treatment focused on symptom relief and prevention of complications. Vaccination was the primary tool used to control and ultimately eliminate the disease.

Question 3

Can smallpox be used as a biological weapon today?

Accepted Answer

Yes, smallpox is classified as a potential bioterrorism agent. Although eradicated, live virus samples are stored in high-security laboratories, and emergency response plans and vaccines are maintained in case of intentional release.

Question 4

What virus causes smallpox, and how did it spread?

Accepted Answer

Smallpox is caused by the variola virus. It spread primarily through respiratory droplets during close, prolonged contact, and less commonly via contaminated items like bedding or clothing.

Question 5

What made smallpox so deadly throughout history?

Accepted Answer

Smallpox had a high mortality rate and left survivors with severe scars or blindness. It spread rapidly and caused widespread epidemics. Its ability to infect large populations before symptoms fully appeared made it especially dangerous.

Question 6

When was smallpox eradicated, and how was it achieved globally?

Accepted Answer

Smallpox was officially eradicated in 1980 after a global vaccination campaign led by the World Health Organization. The last natural case occurred in Somalia in 1977.

Question 7

What are the lasting effects of smallpox, such as scars or infertility?

Accepted Answer

Smallpox survivors often experienced permanent facial scarring and, in some cases, blindness. While infertility was not a universal outcome, complications from severe illness could affect reproductive health.

Question 8

Are smallpox and shingles related or caused by similar viruses?

Accepted Answer

No. Smallpox is caused by the variola virus, while shingles is caused by the varicella-zoster virus-the same virus that causes chickenpox. Although both are viral infections, they belong to different virus families.

Question 9

Why is the smallpox vaccine still important in biodefense planning?

Accepted Answer

Even though smallpox is eradicated, vaccines are stockpiled to provide protection in case of a bioterrorism event. The smallpox vaccine can help prevent infection if given shortly after exposure.

Question 10

Where did smallpox originate, and how did it impact world history?

Accepted Answer

Smallpox is believed to have originated in ancient Egypt or India over 3,000 years ago. It had devastating effects on indigenous populations in the Americas and played a major role in colonial conquests and global population shifts.
