The correlation between ABO blood group and the infection of corona virus disease 2019 (COVID-19) and rate of infection and spread of the disease has been investigated in several studies. Previous studies exhibit a contentious acclamation of evidence thus the objective of the present study was to assess the relationship between different blood groups and the rate of infection at family institution level. The study was conducted on a family after the mother developed a sore throat which led to testing of infection on all the family members. The family comprised of six members whose distribution of blood group were as follows; Father AB+, Mother O+, first born son A+, second born son B+, and two little twins a daughter and son who were both A+. The COVID-19 test results tested positive on the mother who was blood group O+ and their second born son with blood group B+. All the other family members with blood group A+ and AB+ tested negative despite sharing same locality and household facilities. The test results thus indicated some extent of correlation as pertains blood groups and rate of infections. The study used Swab Test and Nasal aspirate accredited Covid 19 test Laboratory results analysis methodology. This is a standard qualitative research method for comparing blood types and its laboratory test results in relation to positivity or negativity to Covid 19 infections. The aim of this study is thus to investigate whether there exists a relationship between the blood groups of family members sharing same household facilities and the risk of SARS-CoV-2 infection and the laboratory results in COVID-19 test.
