Leprosy, also known as Hansen’s disease, remains one of history’s most misunderstood medical conditions. This chronic infectious disease primarily affects the skin, peripheral nerves and mucous membranes, causing severe disfigurement and disability if left untreated.
While modern medicine has made significant strides in treating leprosy through multi-drug therapy, advanced cases still pose unique challenges for healthcare providers worldwide. In its advanced stages, the disease can lead to devastating complications including nerve damage, muscle weakness and the loss of sensation in affected areas. Today’s medical professionals employ sophisticated diagnostic tools and treatment protocols to combat this ancient disease that still affects over 200,000 people annually across the globe.
Advanced:jlbrbsv1sdc= Leprosy
Advanced leprosy presents complex manifestations that affect multiple body systems. Medical professionals classify advanced cases based on specific clinical presentations and bacterial indices to determine appropriate treatment protocols.
Types and Classifications
The World Health Organization categorizes advanced leprosy into two primary classifications:
