Allogeneic stem cell recipients who develop graft-versus-host disease should receive antifungal prophylaxis with oral posaconazole.[2]Patterson TF, Thompson GR 3rd, Denning DW, et al.

Patients undergoing induction chemotherapy for acute myelogenous leukaemia or myelodysplastic syndrome have a reduced risk for invasive aspergillosis (IA) and decreased mortality with oral posaconazole prophylaxis.[2]Patterson TF, Thompson GR 3rd, Denning DW, et al. Practice guidelines for the diagnosis and management of aspergillosis: 2016 update by the Infectious Diseases Society of America. Clin Infect Dis. 2016 Aug 15;63(4):e1-e60.

There are no data to support the use of isavuconazole for prophylaxis.[16]Ullmann AJ, Aguado JM, Arikan-Akdagli S, et al. Diagnosis and management of Aspergillus diseases: executive summary of the 2017 ESCMID-ECMM-ERS guideline. Clin Microbiol Infect. 2018 May;24 Suppl 1:e1-e38.

In patients with chronic granulomatous disease, results from a randomised study showed that itraconazole prophylaxis in addition to the routine prophylaxis with interferon-gamma is safe and effective in preventing IA.[62]Gallin JI, Alling DW, Malech HL, et al. Itraconazole to prevent fungal infections in chronic granulomatous disease. N Engl J Med. 2003 Jun 12;348(24):2416-22.

Benefit from chemoprophylaxis has not been shown in other high-risk populations.
For high-risk patients, rooms fitted with high-efficiency particulate air filters, frequent air exchanges, and positive-pressure ventilation may be useful in limiting exposure to Aspergillus conidia in the hospital setting.[63]Ullmann AJ, Schmidt-Hieber M, Bertz H, et al.

In addition, attention to cleaning of showers and water systems may further reduce exposure.[65]Anaissie EJ, Costa SF. Nosocomial aspergillosis is waterborne. Clin Infect Dis. 2001 Nov 1;33(9):1546-8.

No preventive measures are recommended for chronic pulmonary aspergillosis/aspergilloma. The role of antifungal prophylaxis is uncertain.
