“…De nos jours, en Asie, Ae. albopictus est l'espèce la plus communément rencontrée dans des aires suburbaines et rurales (Tewari et al, 2004), mais aussi dans les villes où persiste une végé-tation arbustive comme à Kuala Lumpur, Singapour ou Tokyo. Ce rapprochement de l'homme lui a permis de coloniser de nouveaux territoires au gré des déplace-ments humains et de l'intensification des échanges commerciaux.…”

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.

We determined abundance of Aedes aegypti mosquitoes and presence of dengue virus (DENV) in females collected from schools in Mérida, México, during 2008 and 2009. Backpack aspiration from 24 schools produced 468 females of Ae. aegypti and 1,676 females of another human biter, Culex quinquefasciatus. Ae. aegypti females were collected most commonly from classrooms followed by offices and bathrooms. Of these females, 24.7% were freshly fed. Examination of 118 pools of Ae. aegypti females (total of 415 females) for presence of DENV RNA produced 19 positive pools (16.1%). DENV-infected pools were detected from 11 (45.8%) of 24 schools and came from different room types, including classrooms, offices, and bathrooms. The overall rate of DENV infection per 100 Ae. aegypti females was 4.8. We conclude that schools in Mérida present a risk environment for students, teachers, and other personnel to be exposed to mosquitoes and bites of DENV-infected Ae. aegypti females.

“…However, in both Sri Lanka, and India this pattern appears to have changed with the disease now spreading to rural areas as well 25 . Although vector densities are generally much higher in urban areas when compared to rural areas, vector densities in rural areas are now seen to be quite high 10,26 . Therefore, the potential 'threat' of major dengue outbreaks in rural areas is present.…”

Emerging infections diseases (EIDs) cause a significant burden on the global economies and are a major public health problem in many countries. The incidence of EID has increased dramatically in recent years, mainly due to zoonotic infections. Sri Lanka has also been significantly affected by EIDs such as dengue, chikungunya and antibiotic resistant bacterial infections. Diseases such as leptospirosis, which have been present for many decades in Sri Lanka are now causing significant public health problems and have been associated with very high mortality. In addition, infections due to the avian influenza A (H5N1) strain, Severe Acute Respiratory Syndrome (SARS) virus and the Nipah virus are some of the pathogens which have a potential of causing severe epidemics in Sri Lanka in the future.As it is beyond the scope of this review to discuss all the current EIDs, it will mainly concentrate on EIDs that have recently caused major public health problems in Sri Lanka and also those that have a possibility of causing major epidemics.
