A silent, invisible and neglected disease...
It is not because that we don't see that it does not exist.

Face Leprosy

Leprosy is a curable, infectious and contagious disease. Leprosy is a notifiable disease but the situation is aggravated by many underreported cases of the disease in Brazil. There are about 30,000 new cases every year, which makes us the 2nd country with the highest incidence, only behind India.

The difficulties in the diagnosis and the stigma that the disease carries make it even harder for people to access treatments, and social minorities suffer the most. The AAL Institute works to strengthen actions for early diagnosis, fighting discrimination with the promotion of social inclusion. As well as supporting the construction of a comprehensive care network for leprosy patients.

Donate and help leprosy patients!

What we do

Founded in 2019 by Dermatologist and Hansenologist Dr. Laila de Laguiche, AAL is a non-profit civil association with an exclusive focus on leprosy, covering both scientific, educational and philanthropic support.

The main goal is to help patients by providing quality care and information, we always value our conduct on ethical and scientific grounds. The Institute grew out of the friendship of several people and the imminent need to organize our society for a blunt action against leprosy and its harms.

Our impact

By the end of 2019, with only 8 months of foundation, the AAL Institute had already passed the main leprosy hyperdemics points in Brazil. Showing solid results from work that has just begun!
