Association of coronavirus infection with neonatal necrotizing enterocolitis.

From the clustered occurrence of numerous cases of necrotizing enterocolitis in newborns, it was possible to associate this disease significantly with infection due to coronavirus-like agents. Prematurity or low birth weight did not seem to affect the development of the disease, at least during the present epidemic. However, associated gas-producing bacteria could influence its severity and play a role in the appearance of pneumatosis. In many aspects the human disease is reminiscent of experimental necrotizing enterocolitis obtained by infection of germ-free newborn animals, as reported in the literature.
