The seasonal reproduction number of XXXX : impacts of climate on transmission.

@entity1 @entity778 @entity281 @entity1800 @entity779
Background. @entity779 is a mosquito-borne @entity1800 and a regular epidemic in Thailand. The peak of the @entity779 period is around June to August during the rainy season. It is believed that climate is an important factor for dengue transmission. Method. A mathematical model for vector-host infectious disease was used to calculate the impacts of climate to the transmission of @entity778 . In this study, the data of climate and @entity779 cases were derived from Chiang Mai during 2004-2014, Thailand. The value of seasonal reproduction number was calculated to evaluate the potential, severity and persistence of @entity281 . Results. The mosquito population was increasing exponentially from the start of the rainy season in early May and reached its the peak in late June. The simulations suggest that the greatest potential for the dengue transmission occurs when the temperature is 28.9   C. The seasonal reproduction numbers were larger than one from late March to end of August and reaching the peak in June. The highest incidences occurred in August due to the delay of transmission @entity1 -mosquito- @entity1 . Increasing mean temperature by 1   C, the number of incidences increases 28.1%. However, a very high or very low temperature reduces the number of @entity281 . Discussion and Conclusion. The results show that the @entity281 depends on the seasonal variation of the climate. The rainfall provides places for the mosquitoes to lay eggs and develop to the adult stage. The temperature plays an important role in the life cycle and behavior of the mosquitoes. A very high or very low temperature reduces the risk of the @entity281 .
