Healthcare Workers - Control
Front-line healthcare workers (FLCHW) who are negative for COVID will receive standard PPE and a pre- and post-study test for COVID-19.
Healthcare Workers - PVP-I
Front-line healthcare workers (FLCHW) who are negative for COVID-19 will receive standard PPE and a pre- and post-study test for COVID-19. Additionally, they will receive PVP-I spray and gargle. Povidone-Iodine Nasal Spray and Gargle: Healthcare workers will receive standard PPE and a pre- and post-study nasal swab COVID19 test. Additionally, they will receive povidone-iodine nasal spray and gargle (10% diluted 1:30) to use at the beginning of their shift, in the middle, and at the end of their shift.
Inpatients - Control
Inpatients who have a 7+ day hospitalization or who are set to undergo a significant surgical procedure will receive standard care and a pre- and post-study COVID-19 test.
Inpatients - PVP-I
Inpatients who have a 7+ day hospitalization or who are set to undergo a significant surgical procedure will receive standard care and a pre- and post-study COVID-19 test. Additionally, they will receive PVP-I gargle and nasal sprays that will be applied shortly after admission or perioperatively. Povidone-Iodine Nasal Spray and Gargle: Patients will receive standard of care treatment and a pre- and post-study nasal spray COVID19 test. Additionally, they will receive povidone-iodine nasal spray and gargle shortly after admission or preoperatively.
Community - Control
Community participants who are negative for COVID-19 will receive a pre- and post-study COVID-19 test.
Community - PVP-I
Community participants who are negative for COVID-19 will receive a pre- and post-study COVID-19 test. Additionally, they will receive PVP-I gargle and nasal sprays. Povidone-Iodine Nasal Spray and Gargle: Community members will receive a pre- and post-study nasal swab COVID19 test. Additionally, they will receive povidone-iodine nasal spray and gargle (10% diluted 1:30) to use at home.

SECONDARY outcome

Timeframe: 3 weeks

Population: Control groups did not receive PVP-I and therefore are excluded from the evaluation of "ease of use" of PVP-I.

Patients will rate the ease of use for PVP-I treatment on a scale from 1-5 after the initial use. Lower scores indicate increased ease of use (1="easy") while higher scores indicate increased difficulty (5="impossible").
