Studies suggest that infants who grow up with dogs in their home are less likely to develop asthma. Researchers may now have found one reason why. Pets, dogs in particular, may protect infants from the effects of a common virus, respiratory syncytial virus (RSV).
Infants with severe RSV infections have an increased likelihood of developing childhood asthma.
The researchers think that exposure to certain microbes in early infancy changes the early composition of an infant’s intestinal flora and this sets the tone for how the developing immune system will respond later in childhood — via redwolf.newsvine.com
