Subsequently, they documented the development of meningitis in 4% of the infants with unsuspected pneumococcemia.4 Two risk factors, a rectal temperature ≥ 38.9 °C and a WBC count > 15,000/cu mm, present together in only 28% of the patients, were recognized to identify 79% of those with positive blood cultures. The following display presents rates from the BCH data:Of 1,000 febrile infants younger than 2 years of age, 769 have rectal temperature ≥ 38.9 °C.Of these 769 infants, 287 have WBC counts > 15,000/cu SN - 0002-922X M3 - doi: 10.1001/archpedi.1979.02130100020002 UR - http://dx.doi.org/10.1001/archpedi.1979.02130100020002 ER -
