An outbreak of chikungunya virus infection is currently underway in the Caribbean, Central America and South America, and autochthonous (local or indigenous) transmission has occurred in the southeastern United States. The mosquito species known to transmit chikungunya- and -are not known to reside in Canada at this time. But how comfortable can we be that this situation will continue? Here we explore four key conditions that must be met for transmission of chikungunya within Canada. We conclude that not all of these conditions have been met and the risk of chikungunya transmission in most of Canada appears to be very low at present. The risk is slightly higher in warmer areas, such as southern British Columbia and isolated locations in south central and southeastern Canada. However, there are significant gaps in our knowledge and ongoing risk assessment, research and surveillance for vectors of chikungunya are indicated.
目前，基孔肯雅病毒感染疫情正在加勒比地区、中美洲和南美洲肆虐，美国东南部也出现了本地（或本土）传播病例。目前已知传播基孔肯雅病毒的蚊种在加拿大尚未出现。但我们能在多大程度上确定这种情况会持续下去呢？在此，我们探讨了基孔肯雅病毒在加拿大传播必须满足的四个关键条件。我们的结论是，并非所有这些条件都已具备，目前加拿大大部分地区基孔肯雅病毒传播的风险似乎非常低。在气候较温暖的地区，如不列颠哥伦比亚省南部以及加拿大中南部和东南部的一些孤立地区，风险略高。然而，我们的知识存在重大空白，因此有必要对基孔肯雅病毒的病媒进行持续的风险评估、研究和监测。
