Bacterial Infections, Lactate Blood Increase, Viral Infection
Conditions
Brief summary
Acute upper respiratory tract infection(AURI) is common in children, and viral infection is the main cause. However, several children with viral infection are easy to suffer from secondary bacterial infection, and the mechanism is unclear.
Detailed description
Lactate is an important molecule in the spread and metastasis of tumor by suppressing the innate immune response. As is known, the immune system is not mature in children and it is reverse related to the age of children. An reasonable hypothesis is that the lactate is a independent risk factor in the children with viral infection progress to bacterial infection. Here, our aim is to test the hypothesis.
Interventions
a child is infected by virus only
a child is infected by virus and progress to bacterial infection
