The diagnosis and treatment of lung infections in children could be improved through clues offered by tiny organisms present in a child's nose, according to new research. Children with respiratory infections have altered microbiome in their noses compared to healthy peers. Microbiome refers to the population of bacteria and viruses present in vast numbers in the body.
This difference predicted how long children had to spend in hospital and helped spot those likely to recover naturally, potentially reducing the need for antibiotics.
Asthma
It''s a lung condition characterized by inflammation of the bronchi and constriction of the airways that result in coughing, wheezing or breathlessness. Allergy and other airway irritants can trigger it

Researchers say the results also help explain why some children are more prone to developing infections than others and could be key to preventing serious lung infections.
Lower respiratory tract infections (LRTIs), including pneumonia and bronchiolitis, are a leading cause of death in under-fives worldwide. Symptoms include shortness of breath, weakness and fever.
![Pneumonia]( "Pneumonia")
Pneumonia is a lung infection that can be caused by a bacteria or a virus. It causes inflammation of the alveoli or the air sacs of the lungs.
Doctors from the University of Edinburgh worked with teams in The Netherlands to take samples from more than 150 children under the age of six hospitalized with LRTI. They compared these with samples from 300 healthy children.
They found that the microbiome in the back of the nose and throat was related to that seen in the lungs, making it easier to understand and diagnose infections.
Children with LRTI had a different microbiome profile - including the types and amounts of individual viral and bacterial organisms - compared with the healthy children, experts found.
These profiles could identify 92 per cent of children as being healthy or ill when combined with factors such as the child's age. This was true no matter what symptoms the child had.
Experts say this breaks with traditional thinking that symptoms predict whether either a virus or bacteria is causing the illness and could impact on a decision of whether or not to use antibiotics.
The microbiome profile also helped the scientists predict the length of the child's hospital stay, a marker of infection severity.

RSV (Respiratory Syncytial Virus) in Children
Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infections. RSV infection is usually mild and self-limiting but symptoms may be severe in young children, the elderly and those with a weak immunity.
