Yaws: Training of health workers at national and districts levels on skin-NTDs

In the context of integration of skin NTDs it is vital to learn to recognize a disease targeted for eradication. At the individual level yaws lesions may mimic other skin diseases. At the community level, it is key to know how to design and implement the total community treatment strategy and monitor its impact. This course aims at providing health workers with the basic knowledge to understand the epidemiology, diagnosis, treatment, impact, eradication strategy and reporting of yaws.

Learning objectives: By the end of this course, you should be able to:

  • Understand epidemiology of yaws at national and district level
  • Describe the clinical aspects of yaws
  • Understand how the diagnosis is made
  • Explain what the global eradication strategy is
  • List how the recording and reporting is done

Course duration: Approximately 2 hours

Certificates: A Record of Achievement certificate will be available to participants who score at least 80% in the final assessment. Participants who receive a Record of Achievement can also download an Open Badge for this course. Click here to learn how.
