Dear visitors to the LASID website,
A warm welcome to all visitors to this website: LASID members, people interested in becoming a member, students, visitors from other societies and patients and their families. These websites offer you much information about Primary Immunodeficiency Diseases (PIDD), resources available through LASID connections and links to other websites that share or complement our goals.
LASID welcomes membership from all Spanish or Portuguese-speaking countries. The core membership hails from countries in North America (México), Central and South America and also the Caribbean. However, we also welcome interested professionals from all other countries that find LASID activities and information helpful to them.
Further information about LASID and its mission are described in detail in other sections of this website: News, History, Membership and Mission. We hope that you will enjoy and find this website useful and we invite you to join our efforts and become a regular visitor.
