Infectious Diseases

  • Herbert B. Allen


Infectious diseases have keywords that represent viral, bacterial, mycobacterial, treponemal, borrelial, fungal, and yeast organisms. Viruses include herpes simplex, varicella zoster, and variola. Even though variola (smallpox) is not present anywhere in the world, because bioterrorism is a constant threat, it is included here. Terroristic use of this organism could lead to devastating plagues because few people are immunized. The clearing of this scourge worldwide has been a remarkable achievement, but it could all be undone by individuals with no sense of humanity.

“Lesions all in the same stage” is the keyword for variola infection, but the phrase gives little information as to the incredible infectivity of this virus. In the French and Indian War (Seven Years’ War in Europe), a group of American Indians, after a victory at Fort William Henry, dug up recent graves to obtain more scalps. The only problem was these scalps belonged to British and colonial subjects who had recently died from smallpox. The Indians who perpetrated this deed all died, for they had limited natural immunity, and the virus was still present and infectious in those scalps.
