Reactivation of VZV causes herpes zoster [1]. This has activity against viruses resistant to other antiviral molecules.

Most of these viral infections are opportunistic in nature and are related to factors influencing engraftment and immune reconstitution [1].

Intravenous immunoglobulins (IVIG) can be given in case of hypogammaglobulinemia and recurrent infections [103,107]. The vaccine should be given ≥24 months following transplantation [11,46]. One aspect of importance in the guidelines is how to evaluate a potential transplant recipient to determine if the patient is an appropriate candidate for the procedure. 2010; 10: 147. 2008; 46: 402-412. Patients with primary, disseminated and severe mucocutaneous HSV infections are placed under contact precautions. Blood. The median time to development of PTLD is around 2 to 4 months [100,102].

Interestingly, haplo-identical transplants using post-transplant cyclophosphamide (PT-Cy) had a low incidence of PTLD [101]. 1. Universal droplet and isolation precautions are practiced as for other respiratory and enteric viruses to prevent a nosocomial spread [11]. HSV2 infections are less frequent and there are broad regional variations [22]. Immunol Lett.

Reference:National Comprehensive Cancer Network. EBV matched donor is recommended to reduce the risk of EBV disease [103]. Using CMV intravenous immunoglobulins as an adjunct therapy is controversial due to lack of data [70].
