Tropical Yaws
Overview
Yaws is a tropical infection affecting the skin, bones, and joints, primarily caused by the bacterium known as spirochete. This infection spreads rapidly through skin contact with an infected person. The bacteria enter the body via an existing cut or skin damage.
Early Symptoms
Within a month, but no later than ninety days after infection, a painless yet noticeable "Mother Yaw" appears. This is an ulcerous papule at the point of entry, resembling a raspberry, with a diameter ranging from 15 to 45 mm. This primary ulcer can persist for up to nine months, and as it heals, additional ulcers may develop.
Progression and Stages
Without treatment, Yaws can progress to a secondary stage within four months. This stage is characterized by additional ulcers, similar in appearance but smaller than the initial one. These growths can merge into thick, fissured plaques, often affecting the feet and causing a distinctive gait. Unfortunately, these secondary growths are irreversible.
In around 10-20% of cases, Yaws can advance to a tertiary stage over a decade or more, resulting in destructive lesions on the skin and bones.
Affected Demographics
Children aged 5 to 11 years are most commonly affected, particularly in regions such as Latin America, the Caribbean Islands, India, West Africa, Oceania, and Southeast Asia. Despite efforts by the World Health Organization (WHO) from 1954 to 1963, outbreaks have been on the rise in recent years.
Diagnosis and Treatment
Yaws is easily identified through blood tests or microscopic examination of a lesion. It can be effectively treated with a single dose of antibiotics such as penicillin, erythromycin, or tetracycline. Recurrence or relapse is quite uncommon.
Conclusion
Prompt diagnosis and treatment are crucial in managing Yaws and preventing its progression, particularly in vulnerable populations.
