Smallpox is a severe and contagious disease caused by the variola virus. Although declared eradicated in 1980 due to successful vaccination campaigns, it is still important to be knowledgeable about its treatment in case of emergencies or bioterrorism. The following are ten steps to treat smallpox:

1. Quarantine: Isolate the infected person from others to prevent spreading the virus.

2. Consult a healthcare professional: Seek medical advice promptly after the onset of symptoms such as fever, headache, body aches, vomiting, and a rash.

3. Antiviral medication: Following a doctor’s prescription, antiviral medications like Cidofovir or Brincidofovir may be taken to reduce the severity and progression of the disease.

4. Pain relief: Over-the-counter pain relievers such as paracetamol or ibuprofen can help alleviate headaches, body aches, and fever associated with smallpox.

5. Hydration: Dehydration may occur due to fever and vomiting; ensure proper intake of water and electrolytes to maintain good hydration levels.

6. Skin care: Smallpox rashes can be uncomfortable and itchy; apply calamine lotion or an ice pack wrapped in cloth on the affected areas for temporary relief. Avoid scratching to prevent infection and scarring.

7. Disinfect surroundings: Regularly clean surfaces that the infected person touches by using disinfectants like bleach or alcohol-based solutions.

8. Vaccination: If available, medical professionals might recommend post-exposure vaccination; although not 100% effective at treating smallpox, it can help reduce severity.

9. Dispose of contaminated items: All clothing, bedding, or personal items that came into contact with lesions should be disposed or washed properly using hot water and disinfectant after handling them with gloves.

10. Emotional support: The patient can be fearful and anxious; ensure proper emotional support and reassurance as they go through the process of recovery.

Remember, early detection and prompt medical attention are crucial in reducing the severity of smallpox. Always follow the advice of healthcare professionals and maintain strict hygiene to prevent further spread of the virus.
