ABSTRACT
High erythrocyte sedimentation rate and D-dimer were also observed.15 The main pathogenesis of COVID-19 infection as a respiratory system targeting virus was severe pneumonia, RNA anaemia, combined with the incidence of ground-glass opacities, and acute cardiac injury. The comparable viral load in a group of asymptomatic carriers of COVID-19 was higher than that of the symptomatic carriers and increasing level of white blood cell count (12.4×109/L), neutrophil count (7.82×109/L), C-reactive protein level (189.2mg/L), low lymphocyte count (0.84×109/L) and platelet count (88×109/L) was found different than the normal range in asymptomatic patients.22 2.1 Clinical Evaluation of Asymptomatic Carriers: Many asymptomatic persons were actually a source of SARS-CoV-2 infection but were considered healthy before they underwent screening. CRP levels, LDH levels, and white blood cell counts were elevated occurred in 10, 13 and 1 patient, respectively.24 According to the study, asymptomatic infection was seldom seen in young people;the proportion with severe COVID-19 was low, and the proportion with ordinary COVID-19 was high. 2.3 Evaluation of Asymptomatic and Symptomatic Carriers: Table-1: Description of general characteristics responsible for evaluation of asymptomatic carriers of Covid-19. General characteristics Asymptomatic Carriers Symptomatic Carriers Normal range White blood cell count (× 10⁹ cells per L) 5.65 9.43 4.00–10.00 Neutrophil count (× 10⁹ cells per L) 3.62 8.21 1.80–6.30 Lymphocyte count (× 10⁹ cells per L) 1.55 0.69 1.10–3.20 C-reactive protein (mg/L) 0.69 202.03 0.0–5.0 3 Prophylactic Regimens for Prevention from Sars Cov-II Virus: This review aims to interrogate the current evidence base, and present the potential immune-mediating, antioxidant, and antimicrobial roles of vitamins A to E in the context of respiratory disease, and to extrapolate this evidence to evaluate the potential roles in the fight against COVID-19.
