The probability of a terrorist attack using the smallpox virus is low, but if it did happen the consequences could be great.
Monday the Illinois Department of Public Health unveiled a strategy to make heath professionals prepared for the possibility of such an attack.
Illinois Public Health Director Dr. John Lumpkin says smallpox vaccinations will be offered to as many as 16-thousand public health and hospital personnel across the state to prepare for the possibility of a terrorist attack. Here, in Winnebago County, health and safety officials are taking precautions as well.
If the smallpox virus is intentionally released in Winnebago County, front line responders in health care facilities, fire and police departments would need to be armed to fight the outbreak. Their weapon: A smallpox vaccine.
"Once this is carried out, it'll contribute substantially to the increased capacity to deal with any kind of a bio-terrorist attack that might involve smallpox," says Winnebago County Health Administrator Mike Bacon.
The Winnebago County Health Department will submit their plan to vaccinate health care professionals to the Illinois Department of Public Health on Friday.
"This is really about increasing the level of preparedness in our community," says Bacon.
Fire and police departments are taking precautions as well, not only through vaccines, but through drills as well.
North Park Fire Chief Steve Ferdinand says the drills allow firefighters to find out where their weaknesses are and to work on them and make them their strengths.
The smallpox vaccination has its share of weaknesses as well. Serious and potentially fatal side effects can occur.

- The name smallpox is derived from the Latin word “spotted” and refers to the raised bumps that appear on the body of an infected person.
Forms of Smallpox
- Two forms of smallpox, variola major and variola minor.
- Variola Major: The sever and most common form of small pox, with a more extensive rash and higher fever. Four types of variola major smallpox:
- Ordinary: The most frequent type, accounting for 90 percent of the cases.
- Modified: Mild and occurring in previously vaccinated persons.
- Flat: Very fatal. Very hard to recover from this form of smallpox.
- Hemorrhagic: Very rare and most serious. Extremely fatal form of smallpox.
- Variola Minor: A less common presentation of smallpox, and a much less sever disease, with death rates historically of one percent or less.
Where Smallpox Originates From
- Smallpox is caused by the variola virus that emerged in human population thousands of years ago.
- Except for laboratory stockpiles, the variola virus has been eliminated.
- Direct and prolonged face-to-face contact is required to spread smallpox.
- Can be spread through direct contact with infected bodily fluids or contaminated objects such as bedding or clothing.
- Rarely, smallpox has been spread by virus carried in the air in enclosed settings such as buildings, buses and trains.
- Humans are the only natural hosts of variola. Smallpox is not known to be transmitted by insects or animals.
Stages of Smallpox Disease
- Incubation Period (7-17 days, not contagious) – Exposure to the virus is followed by an incubation period, which people do not have any symptoms and may feel fine.
- Initial Symptoms (2-4 days, sometimes contagious) – The first symptoms of smallpox include fever, malaise, head and body aches, and sometimes vomiting. The fever is usually high, in the range of 101° F - 104° F.
- Early Rash (4 days, most contagious) – A rash emerges first as small red spots on the tongue and in the mouth. Usually the rash spreads to all parts of the body within 24 hours. As the rash appears, the fever usually falls and the person may start feeling better. However, by the fourth day, the bumps fill with a thick fluid, the fever will raise again and will last until scabs begin to form on the bumps.
- Pustular Rash (5 days, contagious) – The bumps become pustules, sharply raised, usually round and firm to the touch as if there is a small round object under the skin.
- Pustules and Scabs (5 days, contagious) – The pustules begin to form a crust and then scab. By the end of the second week after the rash appears, most of the sores have scabbed over.
- Resolving Scabs (6 days, contagious) – The scabs begin to fall off, leaving marks on the skin that eventually become pitted scars. Most scabs will have fallen off three weeks after the rash appears.
- Scabs Resolved (not contagious) – Scabs have fallen off. Person is no longer contagious.
