“…For example in India, it is estimated that over 1.3 million people across 13 states were infected (Arankalle et al, 2007). In addition, exposed travellers returning from the affected areas to Europe, the USA, Canada, Hong Kong and numerous other countries carried the virus into these new niches where the imported cases were subsequently identified (CDC, 2006;Druce et al, 2007;Hochedez et al, 2007;Lanciotti et al, 2007;Lee et al, 2006;Simon et al, 2007;Taubitz et al, 2007;Watson, 2007). …”

The largest documented outbreak of Chikungunya virus (CHIKV) disease occurred in the Indian Ocean islands and India during 2004–2007. The magnitude of this outbreak led to speculation that a new variant of the virus had emerged that was either more virulent or more easily transmitted by mosquito vectors. To study this assertion, it is important to know the origin of the virus and how the particular strain circulating during the outbreak is related to other known strains. This study genetically characterized isolates of CHIKV obtained from Mombasa and Lamu Island, Kenya, during 2004, as well as strains from the 2005 outbreak recorded in Comoros. The results of these analyses demonstrated that the virus responsible for the epidemic that spread through the Indian Ocean originated in coastal Kenya during 2004 and that the closest known ancestors are members of the Central/East African clade. Genetic elements that may be responsible for the scope of the outbreak were also identified.

“…In 2006, multiple outbreaks of CHIKV resulted in an estimated 2 million cases worldwide . This coincided with the second reported case of CHIKV importation into Australia; a traveller from Mauritius (Druce et al, 2007). The case was rapidly diagnosed and no local transmission occurred.…”

“…The importance of molecular diagnostic tools was highlighted during the Commonwealth Games in 2006, when RT-PCR and sequencing alone enabled the diagnosis and isolation of CHIKV in a traveller, without the availability of serology or virus isolation results (Druce et al, 2007). The ability to rapidly screen potentially infectious visitors or returning travellers to Australia for exotic viruses will rely on the availability of appropriate molecular diagnostic tests.…”

“…Although such cases appear to be rare in New Zealand, with only one reported case of imported CHIKV infection per year, a single infected person may be enough to initiate an outbreak in the presence of an efficient vector in large-enough density, as occurred in the outbreak in Italy. 10 A challenging issue is that, as pointed out by Druce and others for Australia, 34 accurate serologic diagnosis of foreign alphavirus infections is not likely because of the lack of specific assays. In the case of New Zealand, this situation is compounded by the paucity of confirmatory arboviral testing ability.…”

There has never been a locally transmitted outbreak of mosquito-borne disease in New Zealand, but the risk of an outbreak occurring is increasing with on-going interceptions of exotic mosquito vectors across its border, increasing traffic of goods and passengers, higher numbers of viremic travelers arriving, and local, regional, and global environmental change. The risk posed to New Zealand by chikungunya virus is potentially high because of the transmissibility of this virus in subtropical climates, compounded by a population that is predominantly immunologically naive to exotic arboviruses. However, risk reduction in New Zealand should not be considered in isolation but must be viewed within a wider South Pacific context. In this report, we discuss the potential threat posed by chikungunya to the region, focusing in particular on New Zealand, and re-emphasizing the need for a South Pacific–wide approach towards mosquito-borne disease prevention.
