Who can get a leprosy reaction? Almost all persons having
leprosy infection are at risk of developing a reaction.
The risk
is lowest in persons with 1-2 patches and without any nerve
enlargement. The cases diagnosed as PB without any nerve
damage at the time of diagnosis of leprosy have less risk.
PB cases
with some nerve damage at time of diagnosis and MB cases
without any nerve damage at the time of diagnosis have about
16% risk of developing a reaction.
MB cases
with nerve damage at the time of diagnosis are at the greater
risk, about 65%, of developing a reaction.
