“…[127][128][129] The factors that determine the number of cells infected at specific sites may also influence the level of immune activation, and thus have a role in determining the disease phenotype. 111,125 The time between the bite of an infected mosquito and the onset of clinical symptoms is believed to be 3-5 days 130,131 Whether infected individuals in this presyndromic phase are capable of transmitting virus to a biting mosquito is unknown.…”

“…En termes de morbidité et de mortalité, la dengue est considérée comme la plus importante des arboviroses transmises par moustiques (Gubler, 1998). Près de 50 millions de cas et 25 000 morts sont rapportés chaque année (Gibbons & Vaughn, 2002).…”

Summary : AEDES ALBOPICTUS, VECTOR OF CHIKUNGUNYA AND DENGUE VIRUSES IN REUNION ISLAND: BIOLOGY AND CONTROLChikungunya virus (CHIKV) and dengue virus (DENV) are mosquitoborne viruses transmitted by the Aedes genus. Dengue is considered as the most important arbovirus disease throughout the World. Chikungunya, known from epidemics in continental Africa and Asia, has up to now been poorly studied. It has been recently responsible for the severe 2004-2007 epidemic reported in the Indian Ocean (IO), which has caused several serious health and economic problems. This unprecedented epidemic of the IO has shown severe health troubles with morbidity and death associated, which had never been observed before. The two major vectors of those arboviruses in the IO area are Aedes aegypti and Aedes albopictus. The latest is considered as the main vector in most of the islands of the area, especially in Reunion Island. Ae. albopictus showed strong ecological plasticity. Small disposable containers were the principal urban breeding sites, and preferred natural developmental sites were bamboo stumps and rock holes in periurban and gully areas. The virus has been isolated from field collected Ae. albopictus females, and in two out of 500 pools of larvae, demonstrating vertical transmission. Experimental works showed that both Ae. albopictus and Ae. aegypti from west IO islands are efficient vectors of dengue and chikungunya viruses. Since 2006 and all along the epidemic of CHIKV, measures for the control of larvae (temephos then Bacillus thuringiensis) and adults (fenitrothion, then deltamethrine) of Ae. albopictus where applied along with individual and collective actions (by the use of repellents, and removal of breeding sites around houses) in Reunion Island. In order to prevent such epidemics, a preventive plan for arboviruses upsurge is ongoing processed. This plan would allow a quicker response to the threat and adapt it according to the virus and its specific vector.

“…The mean incubation period in humans is 5.5 days, and in A. Aegepti mosquitoes it is 10 days [21], and both follow Gamma distribution. The mean host infection period 1/γ h and adult mosquito life span are 5 and 10 days respectively [12], and also follow Gamma distribution.…”

Abstract.In this work we analyze the post monsoon Dengue outbreaks by analyzing the transient and long term dynamics of Dengue incidences and its environmental correlates in Ahmedabad city in western India from [2005][2006][2007][2008][2009][2010][2011][2012]. We calculate the reproduction number Rp using the growth rate of post monsoon Dengue outbreaks and biological parameters like host and vector incubation periods and vector mortality rate, and its uncertainties are estimated through Monte-Carlo simulations by sampling parameters from their respective probability distributions. Reduction in Female Aedes mosquito density required for an effective prevention of Dengue outbreaks is also calculated. The non stationary pattern of Dengue incidences and its climatic correlates like rainfall temperature is analyzed through Wavelet based methods. We find that the mean time lag between between peak of monsoon and Dengue is 9 weeks. Monsoon and Dengue cases are phase locked from 2008-2012 in the 16-32 weeks band. The duration of post monsoon outbreak has been increasing every year, especially post 2008, even though the intensity and duration of monsoon has been decreasing. Temperature and Dengue incidences show correlations in the same band, but phase lock is not stationary.
