COVID-19 among health care workers and their impact on the health care system in a teaching hospital in Pakistan: A cross sectional observational study.

In conclusion, we found increased risk of COVID-19 for front-line HCWs. Lack of mortality was the favorable outcome. Lack of replacing the infected HCWs possibly explained the marked decrease in hospital admissions, and potential inadequate healthcare delivery during the lockdown. Understanding SARS-CoV-2 among HCWs and their impact on health-care system will be crucial for countries under COVID-19 crises or in case of future pandemic to deliver proper health services.
