* The subjects or subjects' guardians are able to understand and sign the informed consent
* The subjects or subjects' guardians allow to comply with the requirements of the protocol
* Subjects with temperature \<=37.0°C on axillary setting
* The subjects have signed informed consent already

Exclusion Criteria:
