Noma, or cancrum oris, is a fast-acting gangrene infection that destroys the mucus membranes of the oral and facial tissues. The exact etiology of it is unknown, but it most often occurs in malnourished children living in areas with poor sanitation.
Noma has not been widely reported in the LAC region, but approximately 140,000 new cases are diagnosed annually. Mortality rate is about 8.5%. It is most prevalent in sub-saharan Africa.
