    Background: High number of SARS CoV2 infected MESHD patients has overburdened healthcare delivery system, particularly in low-income countries. In the recent past many studies from the developed countries have been published on the prevalence SERO of SARS CoV2 antibodies SERO and the risk factors of COVID 19 in healthcare-workers but little is known from developing countries. Methods: This cross-sectional study was conducted on prevalence SERO of SARS CoV2 antibody SERO and risk factors for seropositivity in HCWs in tertiary care hospitals of Peshawar city, Khyber Pakhtunkhwa province Pakistan. Findings: The overall seroprevalence SERO of SARS CoV2 antibodies SERO was 30.7% (CI, 27.8 to 33.6) in 1011 HCWs. Laboratory technicians had the highest seropositivity (50.0%, CI, 31.8 to 68.1). Risk analysis revealed that wearing face-mask and observing social-distancing within a family could reduce the risk (OR:0.67. p<0.05) and (OR:0.73. p<0.05) while the odds of seropositivity were higher among those attending funeral and visiting local-markets (OR:1.83. p<0.05) and (OR:1.66. p<0.01). In Univariable analysis, being a nursing staff and a paramedical staff led to higher risk of seropositivity (OR:1.58. p< 0.05), (OR:1.79. p< 0.05). Fever HP Fever MESHD (OR:2.36, CI, 1.52 to 3.68) and loss of smell (OR:2.95, CI: 1.46 to 5.98) were significantly associated with increased risk of seropositivity (p<0.01). Among the seropositive HCWs, 165 (53.2%) had no symptoms at all while 145 (46.8%) had one or more symptoms. Interpretation: The high prevalence SERO of SARS CoV2 antibodies SERO in HCWs warrants for better training and use of protective measure to reduce their risk. Early detection of asymptomatic TRANS HCWs may be of special importance because they are likely to be potential threat to others during the active phase of viremia HP viremia MESHD.

    The relationship between SARS-CoV-2 viral load and risk of disease progression remains largely undefined in coronavirus disease MESHD 2019 (COVID-19). We quantified SARS-CoV-2 viral load from participants with a diverse range of COVID-19 severity, including those requiring hospitalization, outpatients with mild disease, and individuals with resolved infection MESHD. SARS-CoV-2 plasma SERO RNA was detected in 27% of hospitalized participants and 13% of outpatients diagnosed with COVID-19. Amongst the participants hospitalized with COVID-19, higher prevalence SERO of detectable SARS-CoV-2 plasma SERO viral load was associated with worse respiratory disease MESHD severity, lower absolute lymphocyte counts, and increased markers of inflammation MESHD, including C-reactive protein and IL-6. SARS-CoV-2 viral loads, especially plasma SERO viremia HP viremia MESHD, were associated with increased risk of mortality. SARS-CoV-2 viral load may aid in the risk stratification of patients with COVID-19 and its role in disease pathogenesis should be further explored.
