Dear Students,
Thank you for your interest in helping with the investigation into mumps(腮腺炎) at University of East Anglia(UEA).
Part 1: What will the oral fluid/saliva sample be tested for?
The oral fluid sample you provide will be tested for mumps antibodies and mumps virus. We will not be reporting results back to individual students. The information gathered will be used to guide public health control of mumps. We will update you via emailing the final outcome to acknowledge your contribution. If you think you have mumps, you will still need to see your GP as per routine.
Part 2: What is involved in the investigation?
(1) We will be contacting you by post to request two oral fluid/saliva samples a few weeks apart and possibly a third sample.
(2) We will contact your GP to collect information on your vaccination records.
What if you change your mind and what safeguards are in place?
Participation is voluntary.
You can withdraw anytime without having to give a reason. Withdrawal will not affect your routine care.
As a public health body, the HPA data collection role is strictly governed. All data will be collected and handled in accordance with strict medical confidences.
Part 3: What to do next if you would like to enroll?
All you have to do now is:
(1)Follow the instructions on the box with regards to taking an oral fluid/saliva swab(棉签).
(2)Complete the request form. If you are unable to complete the vaccination history section, you can leave it blank.
(3)Confirm your consent by signing below.
(4)Send everything (sample form, signed consent and swab sample) back in the prepaid envelope —a stamp is not required.
If you have any queries, please contact Dr. Chee Yung on 0208 327 7603.
Thank you for your time and consideration.
