Ubombo, is a small town in northern KwaZulu-Natal, South Africa about 17 km north-east of Mkuze. It takes its name from the Lebombo Mountain range, on which it is situated. Derived from Zulu Lumbombo, ‘high mountain ridge’. The Zulu name for this village is Obonjeni, ‘on the big nose’, i.e. ‘ridge’. The site and remains believed to be those of the camp where Sir David Bruce and his wife Mary worked between 1894 and 1897, and where Bruce discovered the causative agent of nagana, African trypanosomiasis ("sleeping sickness") and its transmission by the tsetse fly were discovered here.
