“…The phenomenon of vector transport by plane is particularly known from the so called airport malaria. Thereby infected Anopheles mosquitoes are carried over long distances from endemic regions to nonendemic regions and cause unexplainable and often delayed diagnosis of malaria infections, especially near the respective airports [1].…”

Background: The outbreak of vector-associated diseases is determined by different factors. One of them is the existence of appropriate climatic conditions which influence the development of vectors as well as pathogens. Nowadays, accurate data on the occurrence of both vectors and pathogens are often not available in Germany, espite the coastal zones of Lower Saxony (Germany) being former malaria regions. Thus, the question arises, whether a new autochthonous transmission could take place due to the monthly mean temperatures of recent ears taking into consideration the predicted increase in air temperatures according to the IPCC scenarios. Methods: To model areas at risk, the transmission potential for new tertian malaria spreads in respect to emperature was computed in a GIS environment using the Basic Reproduction Rate (R0) formula. Results:We were able to corroborate that the risk of tertian malaria transmission is increasing as temperature s the determining variable of the mathematical model. Conclusions: Lower Saxony is at risk of a new outbreak of tertian malaria assuming no other risk factors than emperature being of relevance.

The sustained climate change is going to modify the geographic distribution, the seasonal transmission gate and the intensity of the transmission of vector-borne diseases such as malaria or the bluetongue disease. These diseases occur nowadays at higher latitudes or altitudes. A further rise in ambient temperature and rainfall will extend the duration of the season in which mosquito vectors are transmitting pathogens. The parasites transmitted by the vectors also benefit from increasing temperatures, as both their reproduction and development are then accelerated, too. Thus, it seemed prudent to examine potential effects on the seasonal transmission gate due to the ongoing and predicted climate changes. Lower Saxony (northwest Germany) is a former malaria region with highest incidences of Anopheles atroparvus and tertian malaria along the coastal zones before malaria had finally become extinct in the early 1950s. Nevertheless, the Anopheles mosquitoes which transmit the malaria pathogens have still been present in Lower Saxony up to now. This together with the climate change-related implications gave reason to investigate whether a new autochthonous transmission could take place if the malaria pathogen is introduced again in Lower Saxony. Thus, the potential spatial and temporal structure of temperature-driven malaria transmissions was mapped using the basic reproduction rate (R (0)) and measured and predicted air temperatures (1947-1960, 1961-1990, 1985-2004, 2020, 2060, 2100, each best case and worst case scenario). This paper focuses on both the summarizing of the results from this risk modelling approach and on the conclusions to be drawn. The recommendations highlight the need to link vector monitoring as one of the key elements of an epidemiological monitoring with the environmental monitoring.
