  2. What is Smallpox? • A serious contagious disease due to a virus • Once worldwide, causing illness and death • It mainly affected children and young adults • Family members often infected each other • In the past, had a death risk of 30%

  3. How is Smallpox Caused? • Smallpox is caused by the variola virus, a member of the orthopoxvirus family • There are two forms: variola major and variola minor • Spreads from one person to another by saliva droplets • Spread through bed-sheets and clothing

  4. How are the Two Forms Different? • Variola Major is a life-threatening form of the virus. It is life-threatening to those who have not been vaccinated • Variola Minor is milder and rarely causes death

  5. What are the Symptoms of Smallpox? • Backache • Delirium • Diarrhea • Excessive bleeding • Fatigue • High fever • Malaise • Severe Headache • Vomiting • Raised pink rash – turns into sores that become crusty on day 8 or 9

  6. What Are Some Complications of Smallpox? • Arthritis and bone infections • Brain swelling • Severe bleeding • Skin infections (sores) • Eye infections • Pneumonia • Scarring • Death

  7. Deletion • World Health Organization (WHO) wiped out all known smallpox viruses in the 1970s except for a few samples saved for government research. • Whether or not to kill the last samples or to preserve it in case there may be some future reason to study it.

  8. Vaccination • If the vaccine is given within day one and four, illness will be less severe or prevented • After the symptoms start, treatment is limited • No vaccine anymore, no smallpox any more • If diagnosed, must be immediately isolated
