The poleward expansion of the distribution of Vibrio spp. has increased the risk of vibriosis outbreaks from multiple species in northern latitudes. Specifically, the coastal area suitable for Vibrio infections in the past 5 years has increased by 50.6% compared with a 1980s baseline at latitudes of 40°N-70°N; in the Baltic region, the highest-risk season has been extended by 6.5 weeks over the same periods . Already, studies have noted greater numbers of Vibrio-related human infections and, most notably, disease outbreaks linked to extreme weather events such as heat waves in temperate regions such as Northern Europe  . By the end of the 21st century, under RCP6.0, the number of months of risk of Vibrio illness is projected to increase in Chesapeake Bay by 10.4 + 2.4%, with largest increases during May and September, which are the months of strong recreational and occupational use, compared to a 1985-2000 baseline . In the Gulf of Alaska, the coastal area suitable for Vibrio spp. is projected to increase on average by 58 + 17.2% in summer under RCP6.0 by the 2090s, compared to a 1971-2000 baseline  .
