Herpes simplex virus\u2013seropositive patients undergoing allogeneic hematopoietic stem-cell transplantation or leukemia induction therapy should receive nucleoside analog-based antiviral prophylaxis, such as acyclovir. Pneumocystis jirovecii prophylaxis is recommended for patients receiving chemotherapy regimens that are associated with a &gt; 3.5% risk for pneumonia as a result of this organism (eg, those with \u2265 20 mg prednisone equivalents daily for \u2265 1 month or on the basis of purine analog usage). Treatment with a nucleoside reverse transcription inhibitor (eg, entecavir or tenofovir) is recommended for patients at high risk of hepatitis B virus reactivation. Recommendations for vaccination and avoidance of prolonged contact with environments that have high concentrations of airborne fungal spores are also provided within the updated guideline.
