There were six symptomatic cases and one death who had evidence of virus-associated hemophagocytic syndrome at autopsy. Amantadine prophylaxis was offered to the NICU staff, and amantadine therapy was given to five of the six symptomatic infants. Mechanical ventilation, gestational age, birth weight, Clinical Risk Index for Babies score, and twin pregnancy were associated with acquisition of influenza A on univariate analysis. Mechanical ventilation (odds ratio [OR], 6.2;<jats:italic>P<\/jats:italic>=.02) and twin pregnancy (OR, 7.0;<jats:italic>P<\/jats:italic>=.04) remained as significant risk factors for infection on multiple logistic regression analysis.
