Transmission map of the 4 patients infected with genotype 2 Pneumocystis jirovecii in the hematology ward, showing that any meeting between two Gt2 patients must have been in the daycare center because no 2 patients were concomitantly hospitalized in the same unit of the ward. Patient 2 met Patients 5 and 10 once each before developing PCP and twice each after developing PCP while under treatment followed by secondary prophylaxis, including once when both were met on the same day. Patient 2 never met Patient 7. Patient 5, the only one to have met all 3 others at least once, met Patient 2 three times, Patient 7 twice, and Patient 10 five times. Patient 7 met Patient 5 twice and Patient 10 three times (twice before the diagnosis of PCP, and once thereafter). Patient 7 never met Patient 2. Patient 10 met Patient 2 twice and Patient 5 five times, including one occurrence where both were met on the same day. Patient 10 met Patient 7 three times.
