Viral respiratory tract infections include the common cold and influenza which doctors often refer these to upper respiratory infections (Uris) while infections of the lower respiratory tract refers to symptoms in the windpipe, airways, and lungs. Children develop on average six viral respiratory tract infections each year while they possibly suffer both the upper and lower respiratory tracts. The symptoms typically peak after 3-5 days and then gradually clear. Children tend to get more upper respiratory tract infections than adults because their antibody levels are low to again many of the RTI viruses. Further, they are easily in touch of virus when their hands come into contact with nasal secretions from an infected person. Children in child care centare more likely contact with an infectious agent and are more likely to be infected with viral respiratory infections than those living at home.
