Hypothesis
Is Aedes albopictus the primary vector responsible for the 2007 Chikungunya outbreak in Libreville, Gabon?
Conclusion

Supporting Evidence
- Aedes albopictus was found to be more susceptible to the Chikungunya virus than Aedes aegypti.
- The study confirmed that Aedes albopictus was the primary vector during the outbreak.
- Chikungunya virus was isolated from Aedes albopictus mosquitoes collected during the study.
Takeaway
Scientists found that a type of mosquito called Aedes albopictus was the main bug spreading a sickness called Chikungunya in Gabon.
Methodology
The study involved trapping mosquitoes in Libreville and conducting laboratory experiments to assess their ability to transmit the Chikungunya virus.
Limitations
