Westward Expansion Diseases
Transcript of Westward Expansion Diseases
Symptoms of Smallpox
Some of the symptoms of smallpox include:
Mouth sores and blisters that spread the virus into the throat.
A progressive skin rash
Blindness (commonly resulted when blisters form near the eyes.
Smallpox is one of the many diseases that was very deadly during the time of the westward expansion.
What is Smallpox?
Smallpox virus preferentially attacks skin cells, causing the characteristic pimples (called macules) associated with the disease.
By days 12-15 the first visible lesions start to appear on the mucous membranes of the mouth, tongue, throat, and throat.
This progressive skin rash follows a predictable pattern:
The rash starts with flat red sores that a few days later become raised bumps.
The bumps turn into fluid-filled blisters.
The blisters become pustules.
The pustules crust over, usually in the second week of smallpox.
Scabs form over the blisters and then fall off, usually in the third week of the disease, resulting in scars that are often disfiguring.
This is one stage of the smallpox.
During the westward expansion smallpox was a disease that took many peoples lives. Smallpox is a serious and contagious disease, so if somebody got the disease sometimes it would spread through entire "parties" or "groups" killing many.
