Belgian researchers working with Danish partners report that respiratory syncytial virus (RSV) infections in early infancy are linked to a higher risk of childhood asthma, especially in children with a genetic tendency to allergies. In experimental models, protecting newborns from RSV prevented the immune changes associated with later asthma. The findings, published in Science Immunology, highlight potential long-term benefits of emerging RSV prevention tools.
Most Brazilian states report severe acute respiratory syndrome (SRAG) at alert, risk, or high-risk levels, according to Fiocruz's InfoGripe bulletin released on April 29. Cases are driven mainly by influenza A and respiratory syncytial virus (RSV), which circulate more in autumn and winter. Exceptions are Rio de Janeiro, São Paulo, and Rio Grande do Sul.
