Expert comments for publication: 
Incredibly, information from the donor lasted ten months to be communicated to the recipient centre. Although targeted treatment with benznidazol was delayed, recipient finally did well and serology became negative. The infection in the donor does not contraindicate transplantation with the exception of heart and gut. Recipients must be treated preemptively or followed up with serology and NAT to start treatment as soon as tests turned positive.
