1 Yaws (Treponema pertenue)
Devin Bryner

2 Description/M.O. Yaws is a bacteria.
It is transmitted through skin-to-skin contact and enters through a pre-existing cut, bite, or scratch. It causes warty nodules to appear on the skin.

3 Victims/Hideout Three-quarters of the victims are under 15. It’s most common in kids 6-10 years old. It is found in humid tropical regions. It was believed to have originated in Africa and spread to other countries through immigration and slavery.

4 Most Common Injury Stage 1: Appears within 90 days of getting infected, usually under a month. Painless warty nodules appear on the skin. Stage 2: Months to years later, wide-spread lesions show up. They often ulcerate and become infected. They usually heal after six months. Stage 3: About 10% develop to stage 3 after 5 to 10 years. Causes widespread bone, joint, and soft tissue pain. This may include the bone and cartilage of the nose.

5 Armed and Dangerous? I would rate Yaws 3/10 in the degree of damage caused, but it depends on the stage. Stages 1 and 2 don’t cause much damage, although Stage 2 is very infectious. Stage 3 causes a lot of damage, but few people develop that far.

6 Number of Victims & Most Effective Weapons
Around million people were affected in the 1950s, but it is unknown how many people are infected today. It is treated by one intramuscular penicillin injection or by a course of penicillin tablets. A single oral dose of azithromycin is also as effective as the injection.
