Baby's first cold can last longer depending on nose-dwelling bacteria

(European Lung Foundation) New research on the types of bacteria living in babies' noses could offer clues as to why some recover quickly from their first cough or cold, while others suffer for longer. The study suggests that babies who have a wide variety of different bacteria living in their noses tend to recover more quickly from their first respiratory virus, compared to those who have less variety and more bacteria from either the Moraxellaceae or Streptococcaceae family.
