A Trial of Two Mask Systems in Preventing SARS CoV-2 in Healthcare Workers (HCW)

A Cluster Randomized Trial of Two Mask Systems (Acteev™ N95 + Acteev™ Fabric Masks vs. Standard N95 + Fabric Masks During Shifts & in Community) in Preventing Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2) in HCWs

A cluster randomized trial will be conducted to evaluate the difference between an Acteev™ system (Acteev™ N95 masks YQD8008 during shifts+ Acteev™ fabric masks in community) and a standard system (standard N95 masks during shifts+ fabric masks in community) in preventing Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2)in healthcare workers(HCWs).

This is a maximum 10-week (8-week intervention+2-week follow up) two-armed controlled study to investigate efficacy of Acteev™ system (Acteev™ N95 masks YQD8008 during shifts+ Acteev™ fabric masks in community) compared with standard system (standard N95 masks during shifts+ fabric masks in community) in HCWs working in high-risk hospital wards (ICU, emergency), against the prevention of SARS CoV-2 infection. Prospective HCWs will be identified for the study by the study investigator/study team and be invited for participation in the study. All study procedures will begin only after obtaining written informed consent from the subjects. Subjects will be randomized in one of the two arms mentioned below after meeting all the study eligibility criteria: Arm 1:Acteev™ system (Acteev™ N95 masks YQD8008 during shifts+ Acteev™ fabric masks in community) Arm 2: Standard system (standard N95 masks during shifts+ fabric masks in community).

Participants will wear the mask on every shift for 8 consecutive weeks. Participants in Arm 1 will be supplied adequate number of Acteev™ N95 masks YQD8008 during 8-hour shift and Acteev™ fabric masks for community use.

Participants will wear the mask on every shift for 8 consecutive weeks. Participants in Arm 2 will be supplied with adequate number of standard N95 masks during 8-hour shift and fabric mask for community use.

The efficacy of Acteev™ system vs standard system in preventing SARS CoV-2 infection in health care workers

• Number of cases with laboratory-confirmed for viral SARS CoV 2 respiratory infection using RT-PCR with or without two or more respiratory symptoms or one respiratory symptom and/or a systemic symptom

8 weeks of wearing the masks (with the option of increasing to 12 weeks) with 2 weeks of following up.

The efficacy of Acteev™ system vs standard system in preventing CRI/ILI infection in healthcare workers

• Number of cases with Clinical Respiratory illness defined as two or more respiratory symptoms or one respiratory symptom and/or a systemic symptom along with laboratory-confirmed viral and bacterial respiratory infection other than SARS CoV 2 (Including respiratory syncytial virus (RSV), human metapneumovirus(hMPV), influenza A (H3N2), (H1N1) pdm09, influenza B, parainfluenza viruses 1-4, influenza C, rhinoviruses, severe acute respiratory syndrome (SARS) associated coronavirus (SARS-CoV), coronaviruses 229E, NL63,OC43 and HKU1, adenoviruses and Bacteria like Bordetella pertussis, Bordetella parapertussis, Chlamydia pneumoniae, Mycoplasma pneumoniae)

8 weeks of wearing the masks (with the option of increasing to 12 weeks) with 2 weeks of following up
