Methods/Case Report retrospective review all SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) was performed RT-PCR tests collected at VAMC from March 17th, 2020 May 20th, collect information. Patients with no known were excluded. Results (if Case Study enter NA) 81 patients tested during study period. This had an age range 45 99, consisted 80 males 1 female, racially proportioned 57 African Americans (70.3%), 2 Asian (2.5%), Hispanic American (1.2%), 20 Caucasian (24.7%), one unknown race (1.2%). The distribution among these as follows: 39 O+ (48.1%), 3 O- (3.7%), 15 B+ (18.5%), AB+ 18 A+ (22.2%), A- (3.7%). Conclusion Comparison groups general population reveals proportion are similar. provides proposition type predispose significantly
