Right here’s the newest on the continued RSV surge and the seek for a vaccine to assist forestall it.

Most youngsters will be capable of struggle off RSV inside every week, however these with weaker immune and respiratory techniques might battle a bit extra and want hospital-based care. Kids who’ve issue respiratory would possibly should be hospitalized for added oxygen given by means of a nasal tube, whereas different infants may should be rehydrated in the event that they haven’t been consuming or ingesting.
