Mission Statement:


The International Immunocompromised Host Society (ICHS) is the premier, international, multidisciplinary forum for scientific and clinical interchange to improve understanding and management of the immunocompromised host.



ICHS has an active membership of approximately 600 members; mainly practicing clinicians and researchers. ICHS holds an International Symposium on Infections in the Immunocompromised Host every other year. The 2022 Symposium will be the 22nd Symposium where we plan to  meet in Basel Switzerland.





The ICHS is governed by a Council and Executive Committee of the Council who are voted into office by the membership.

Joint Initiatives with Societies:


ICHS partners with other societies and conferences to actively support education about the immunocompromised patient.  Joint workshops, symposia, meet-the-experts sessions are held in conjunction with ICAAC, IDSA, ECCMID and TIFI.


ICHS Awards:


ICHS sponsors awards for the best abstract on infections in the immunocompromised at various events.


Mycology Initiative:


ICHS has cosponsored a series of initiatives on Mycology.  The Mycology Initiative is an accredited education program for physicians, health-care practitioners and medical students. It is designed to provide leading edge information in the epidemiology, risk factors, diagnosis and treatment of invasive fungal infections in the immunocompromised host. 


There are three Mycology Initiatives published, with several more planned for the future.  Members receive copies of the monographs and have access to download the slides from the Members Section of the web site.


Mycology Initiative Program One: Opportunistic Fungi in the Immunocompromised


Mycology Initiative Program Two: Opportunistic Fungi in Cancer and Hematopoietic in Stem-Cell Transplant Patients


Mycology Initiative Program Three: Fungal Infections in Solid Organ Transplant Recipients
