CRP and infection: In keeping with these findings, Park et al. studied nearly 30,000 veterans with Alpha, Delta, and Omicron infections [40] and observed that the risk of having enhanced levels of C reactive protein was higher in those infected by Delta (odds ratio [oR], 2.30; 95%CI, 2.18–2.4) or Alpha (OR, 2.29; 95%CI, 2.14–2.45) compared to Omicron.
