Princeton University-led researchers studied annual outbreaks of respiratory syncytial virus (RSV) in one of the first examinations of how climate change could affect diseases such as influenza that are transmitted directly from person to person. They found that while outbreaks of RSV could become generally less severe, infections may become more common, which could leave people more vulnerable to the virus over the long term, particularly children.
