Methods The incidence of nosocomial infections among 30 70 hospitalized neonates hospitalized in our hospital from January 1996 to December 1997 was retrospectively analyzed. Results The overall hospital infection rate was 72%. With the decrease of neonatal weight, the relative risk of nosocomial infection increases; the nosocomial infection rates of different weight groups have extremely significant differences. Neonatal nosocomial infections occur in 89% of skin sites on the mucosa. Conclusion Low birth weight children prone to nosocomial infection, suggesting that special attention should be paid to low birth weight neonatal care and care
