| investigation of seroprevalence of respiratory virus infections in an infant population with a multiantigen fluorescence immunoassay using heel-prick blood samples collected on filter paper. | respiratory viruses are an extremely common cause of childhood morbidity. however, the current seroprevalence of viruses in infant populations is difficult to establish because invasive venipuncture may be technically and ethically unacceptable. this prospective study aimed to establish the seroprevalence of respiratory viruses in an infant population by use of a novel multiantigen fluorescence immunoassay against common respiratory viruses, using heel-prick blood samples collected on filter pap ... | 1999 | 10367768 |
