Hypothesis
Ultra-violet radiation is responsible for the differences in global epidemiology of chickenpox and the evolution of varicella-zoster virus as man migrated out of Africa.
Conclusion
The study suggests that ultra-violet radiation affects the transmission and evolution of varicella-zoster virus, leading to different epidemiological patterns in tropical and temperate regions.
Supporting Evidence
- Chickenpox is less common in tropical children compared to temperate children.
- UV radiation levels are significantly higher in temperate zones during summer, which may inactivate the virus.
- Different genotypes of varicella-zoster virus have been classified based on geographic locations.
Takeaway
This study says that sunlight can change how chickenpox spreads and how the virus changes over time, especially when people move from one place to another.
Methodology
The hypothesis is testable by exposing different virus genotypes to ultra-violet radiation and quantifying virus survival by plaque forming units or quantitative mRNA RT-PCR.
