Seroprevalence of MERS-CoV IgG in Healthcare Workers

October 29, 2015 updated by: Hee Jung Choi, Ewha Womans University Mokdong Hospital

Seroprevalence of IgG Antibodies to Middle East Respiratory Syndrome Coronavirus in Asymptomatic Healthcare Workers After Treatment of Confirmed MERS Patient

The investigators aim to do serosurvey of healthcare-personnel who had participated in treatment of confirmed patients of Middle-East respiratory syndrome. The investigators collected the base-line (pre-exposure) serum of healthcare-personnel in a few centers, and will collect the post-exposure serum from about 25-30 centers in which confirmed MERS patients had been treated.

The investigators will deduct the seroprevalence of MERS-CoV IgG among the healthy healthcare-personnel, and calculate the sero-conversion rate if possible. The investigators will subdivided the seroprevalence according to the degree of exposure and preparedness of personal protective equipment.

Detailed Description

We aim to deduct the seroprevalence of healthcare-personnel (HCP) who had participated in treatment of confirmed patients of Middle-East respiratory syndrome.

In first step, we collected the base-line (pre-exposure) serum from the HCP who worked in the hospitals in which confirmed MERS patients were treated. Pre-exposure serum was collected in a few centers. If the serum was drawn within 3 weeks from initial exposure, then the serum was considered adequate as pre-exposure. (Because, antibody against the MERS-CoV would be produced after more the 17-21 days of exposure). The serum was frozen.

In second step, we will collect the post-exposure serum from the HCP who worked in the hospitals in which confirmed MERS patients were treated or detected. We plan to include 25-30 centers. The timing of sample collection is 6-8 weeks after last contact with confirmed MERS patients. The serum will also freeze.

In third step, we will assay the presence of antibody in collected sample. We will use MERS-CoV ELISA kit (EUROIMMUNE co.) as screening test and MERS-CoV IFA kit (EUROIMMUNE co.) as confirm test.
