Enterovirus mainly targets infants and young children causing respiratory infection, herpes pharyngitis, hand-foot-mouth disease, epidemic chest pain, myocarditis and pericarditis, eye diseases, aseptic meningitis and other diseases. Enteroviruses are highly contagious and have a high asymptomatic infection rate, which is easily cause the outbreak of disease. Hand-foot-mouth disease is mainly caused by EV71 and CA16. EV71 can cause neurological system symptoms, even leading to death.

According to the evaluation and analysis of product performance and clinical trial results, the sensitivity of this kit is higher than 94%, the specificity of this kit is higher than 95%. When the sample concentration is too low (Ct> 34),100%positive results cannot be reached in every test within 10 repeated amplifications.
There are no cross-reactivities with other viruses that infect the same position of the body or have similar infectious symptoms (e.g. varicella-zoster virus, influenza virus A, influenza virus B, Adenovirus, herpes simplex virus, Rhinovirus, mycoplasma pneumonia, chlamydia pneumoniae, HBV, HCV, streptococcus, Staphylococcus aureus and pneumococcus).
In the tested sample, when the concentrations of common interfering substances such as blood, pus and the medication drugs for hand-foot-mouth disease treatment such as methylprednisolone, acyclovir and ribavirin, is 10%, 5%, 0.1 g.L-1, 0.1g.L-1 and 0.1g.L-1, respectively, the performance of the kit will not be affected.
Carry out enterovirus nucleic acid test in the infant eruption period, and even before the eruption showing continuous fever, poor mental health, vomiting and other symptoms to clarify whether the patient has enterovirus infection to, so as to early prevention, early treatment.
For severe cases with atypical rash, clinical diagnosis is difficult, and it is more necessary to carry out etiological diagnosis to determine whether there is enterovirus infection.
HFMD has a fast onset rate, and the detection of enterovirus nucleic acid can achieve early intervention and early blocking.
