Background: Exist indirect pathways from climate change to alter transmission dynamics of disease vectors (e.g. triatominae and mosquitoe) and vector-borne diseases (e.g. chagas disease and dengue). Also, food and water borne diseases. A direct pathway to acquire infectious disease is the altered air chemistry with high air pollutants concentrations like ozone and other human airways irritants. Aims: Obtain epidemiological evidence related with climate change locally in the last three years. Methods: An ecological design trying to obtain epidemiological evidence to suggest hypothesis about climate change phenomena and how is reshaping the distribution of infectious diseases across local scale. We obtained epidemiological surveillance data from laboratory and local disease register called SUIVE in 2009-2011. Also, meteorological conditions like temperature and precipitations were obtained from a state meteorological stations proportioned by the National Water Comission. Results: We found 258 positive cases of Chagas disease during 2009-2011, some of them in places where were not reported in the past like Maravatio region (4 cases). 3 cases of coccidiomycosis were investigated in the state laboratory in Buenavista region in 2011. An outbreak of vibrio parahaemolyticus related with sea foodborne was registered in april 2010. And, finally, a set of acute diarrhoeal, respiratory, dermal, conjunctivitis and parasitic infections were reported after flooding on february 2010 in Angangueo region. Temperature on april 1950-2000 was in range 15(°C) to 30(°C). Rain was 3mm- 32mm in the same period. Temperature and rains scenarios, MPIECHAM 5, A2, on april 2030 and 2050 were 18(°C) to 31(°C) and 19(°C) to 33(°C), respectively. Precipitation was 4mm-12mm and 2mm-16mm, respectively. Conclusions: This is among the beginning of empirical evidence of epidemics diseases with epidemiological studies that anthropogenic climate change is driving the emergence of infectious diseases in Michoacan state of Mexico.
