When influenza is circulating within the community, patients with an influenza-like illness who have both cough and fever within 48 hours of symptom onset are likely to have influenza and the administration of influenza antiviral therapy may be appropriate to consider.

Human mannose binding protein (MBP) is a C-type serum lectin involved in first-line host defense against a variety of bacterial, fungal and viral pathogens. Recently an association was found between low levels of serum MBP and an increased frequency of recurrent infections in infants. A particular genotype, in which glycine is substituted by aspartic acid at codon 54 of MBP in the fifth collagen repeat, shows apparent concordance with the clinical phenotype. We report, however, that this genotype occurs in 5% of the population and encodes a functional protein. Our results indicate that the Gly54Asp allele does not account for a deficiency state, but instead suggest that MBP may have two predominant allelic forms that have overlapping function and differ only in their ability to activate the classical pathway of complement.
