It would appear that the effects of influenza must vary with the severity of the epidemic, and more particularly with the frequency of pneumonic complications. As a rule, any septic condition offers a worse prognosis in pregnancy. Several instances have been reported of transmission of the offending bacteria to the foetus.—J. Whitridge Williams (1903)
