Professionals in physical contact with other persons are at the greatest risk of contracting the virus. Health care workers are in close proximity to their patients. On a daily basis, they encounter symptomatic patients who seek medical attention. Even the asymptomatic patients could potentially carry the virus. Therefore, they are at a much higher risk compared to other professions. As much as this information sounds obvious, it is crucial to always keep it in mind considering the challenges they are facing and mainly the shortage in appropriate supply and PPE to keep them safe.
