It is not only premature babies and children with underlying diseases who suffer from serious respiratory syncytial virus (RSV) infections. Even healthy, full-term babies are at significant risk of intensive care or prolonged hospitalisation – especially during the first three months of life. This is according to a comprehensive registry study from Karolinska Institutet in Sweden published in The Lancet Regional Health – Europe.

Scientists have discovered why older people are more likely to suffer severely from the flu, and can now use their findings to address this risk.

In a new study, which is published in PNAS, experts discovered that older people produce a glycosylated protein called apoplipoprotein D (ApoD), which is involved in lipid metabolism and inflammation, at much higher levels than in younger people. This has the effect of reducing the patient’s ability to resist virus infection, resulting in a more serious disease outcome.
