HFMD occurs mainly in children under 10 years old, but may also occur in adults too. Everyone is at risk of infection, but not everyone who is infected becomes ill. Infants, children, and adolescents are more likely to be susceptible to infection and illness from these viruses, because they are less likely than adults to have antibodies and be immune from previous exposures to them.

Obstructive Lung Disease in Children After Allogeneic Bone Marrow Transplantation By Kirk R. Schultz Gordon J. Green David Wensley Michael A. Sargent . Magee John J. Spinelli Sheila Pritchard Jeffrey H. Davis Paul . Rogers Ka Wah Chan and Gordon L. Phillips Obstructive lung disease OLD has been described as a significant complication after allogeneic bone marrow transplantation BMT . The incidence of OLD in adults appears to be low 3 but there is little data for children. We analyzed 89 consecutive pediatric allogeneic BMTs years post-BMT performed at British Columbia s Children s Hospital from 1980 to 1992 for evidence of OLD. Diagnosis of OLD was based on clinical findings nonproductive cough wheezing and dyspnea with no evidence of infection pulmonary function tests FEV 80 and 60 predicted lung biopsy and computed tomography scan. Sixty-seven of the 89 children evaluated survived 290 days and were
