Transmitted by direct or indirect transfer of eye and nose discharges of infected people
Transmitted by person to person (direct or indirect)
Buruli Ulcer
The form of transmission is unknown but contaminated water or
mud is thought to be part of the transmission mode.
Caused by Mycobacterium ulcerans
Yaws
