Many viruses can apparently be dealt with by:
- Vaccination (if avaiable & affordable and person is willing to have the side-effects - which can include death)
- Getting Vitamin D into your blood
- Increasing the vitamin D actually getting to cells Magnesium, Omega-3, Resveratrol, etc

Background and aims
It has been demonstrated that 1,25-hydroxyvitamin-D3-24-hydroxylase, encoded by CYP24A1 gene, is a key enzyme that neutralizes the active vitamin D3 metabolite 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] in response to hepatitis C virus (HCV) infection. This study aimed to investigate whether CYP24A1 genetic variation is associated with HCV infection outcomes.
848 HCV chronically infected subjects, 507 natural clearance subjects, and 1017 uninfected controls were enrolled. Nine single nucleotide polymorphisms (SNPs) in the CYP24A1 gene were genotyped using the Sequenom MassARRAY platform.
After adjusting for age, gender, and routes of infection, logistic regression analyses showed that rs6013897-A was associated with an elevated risk of HCV infection (P < 0.05). In addition, this study has also demonstrated that rs6068816-T significantly reduced the risk of chronic HCV infection, while rs3787557-C, rs6022999-G, and rs2248359-T significantly increased the risk of chronic HCV infection (all P < 0.05). Haplotype analysis suggested that, compared to the most frequent Trs6068816Trs3787557Ars6022999Crs2248359 haplotype, the
- CTGT haplotype (adjusted OR = 1.376, 95% CI = 1.092-1.735, P = 0.007) and
- CCAC haplotype (adjusted OR = 1.483, 95% CI = 1.139-1.929, P = 0.003)
were associated with an increased risk of chronic HCV infection.
Conclusion: These findings indicate that SNPs in CYP24A1 gene may contribute to the risk of HCV infection and chronic HCV infection among high-risk Chinese population.
