Objectives. To determine the prevalence of covide19 infection and to identify the lifestyle factors and nutritional status associated with the epidemiological profile of covid19 patients. Methods. This cross-sectional survey was carried out in the eighteen Iraqi governorates, from 1st August to 20th of October 2020. At the end of this study, 433 participants were recruited . Results. The prevalence of coronavirus infection was 37.18%. Smoking and Active physical activity were relatively higher for covid19 patients who are male, and belonged to the under 45 age range were 91.3%. It notices that covid19 patients who smoking and had active physical activity were married, residence in urban, and worked. Likewise, covid19 patients who had equal or more than institute/college level of education are smokers and had active physical activity. Obesity prevalence was higher for patients aged <45 (92.2%), and higher for females (51%). The proportion of obese was generally higher for married and for those living in urban areas (92.2%). Obesity was significantly more common among those in worked (70.6%). Conclusions. Of note is the high prevalence of covid19 infection observed. A strong correlation between the prevalence of active physical activity among covid19 patients and gender, marital status, residence, education, and occupation. As unexpected, the prevalence rate of obesity among covid19 patients on correlating with socio-demographic status did not yield a significant difference.

Background: SP110 plays an important role in microbial immunity and regulating macrophage biological activity, which may protect against tuberculosis. To investigate whether SNPs of SP110 are associated with susceptibility to latent TB infection in an Iraq population. Hence, identifying SNPs in these genes could be used as a marker to screen individuals at risk of latent TB Infection. Method: A case-control study was conducted to investigate the polymorphism of the SP110 gene by the Sanger sequencing method in 50 individuals with latent TB infection and 40 healthy controls. Result: The findings demonstrated that the A allele and the genotype "GA" of  rs9061 was significantly associated with LTBI risk (  p=0.033; OR: 2.32; 95 %CI: 1.07 -  5.03  and p=0.035; OR: 3.14; 95 % CI: 1.08 - 9.07 ), respectively. In addition, the results of the current study showed that the genotype CT of  rs28930679 was significantly associated with the risk of latent TB infection (p=046; OR:2.64;95%CI:1.02 - 6.86). Conclusion: The results found that genetic variants of the SP110 (rs9061, rs28930679 ) are associated with susceptibility to latent TB and single nucleotide polymorphism of the SP110 gene  show the predictability of latent TB risk and subsequent TB development.
