Brief Summary:
To develop a real-time diagnostic technique with Virosensor for Enterovirus 71 and Influenza Virus detection, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of Enterovirus 71 and Influenza Virus, the investigators evaluate the performance of virosensor , including reproducibility, sensitivity, specificity, and cross-reaction. The potential factors which may interfere with the results would be investigated. With such technique, the investigators hope to make early diagnosis and give Enterovirus 71 and Influenza Virus patients early treatment to reduce the complications and case-fatality rate.

Condition or disease Intervention/treatment Phase
Enterovirus 71 and Influenza Virus Device: virosensor Not Applicable

Detailed Description:
  1. Sample acquirement： At National Taiwan University Hospital in Taiwan, we will enroll patients who have influenza-like illness or enterovirus infection . We will take three throat swabs for each patient: one for viral isolation, one for RT-PCR and the last for the Virosensor - based real-time diagnosis.
  2. Virosensor diagnosis： Virosensor (structural chip-based optosensing virus probing system), which is for the rapid and sensitive detection of viral antigen in medical samples, will be used for analyzing the interaction kinetics between anti-influenza-virus (or anti-Enterovirus 71-virus) and its influenza virus antigen (or Enterovirus 71 antigen) present in patients'and normal samples.
  3. Gold standard： viral isolation and RT-PCR

Arm Intervention/treatment
Experimental: virosensor
virus detection
 Device: virosensor

virosensor, which was developed for the rapid and sensitive detection of viral antigen in medical samples, will be used for analyzing the interaction kinetics between anti-influenza-virus (or anti-EV71-virus) and its influenza virus antigen (or EV71 antigen) present in patients and normal samples.

The system incorporates the use of chip formats. In antibody probing, antibodies are bound as a suitable probe, which specifically and selectively binds targeted molecules (virus antigen) in the test specimens.

Primary Outcome Measures :
  1. Influenza virus or Enterovirus 71 detection [ Time Frame: 1 Day ]
    In comparison with results from viral isolation and RT-PCR of influenza virus or Enterovirus 71 , we evaluate the performance of virosensor, including sensitivity, specificity, cross-reaction and reproducibility.
