Diseases that are caused by global warming

"Global warming and the associated climate changes are predictable. They are enhanced by burning of fossil fuels and the emission of huge amounts of CO2 gas which resulted in greenhouse effect. It is expected that the average global temperature will increase with 2-5 ° C in the next decades.

The lives of millions of people especially in developing countries will be at risk in direct and indirect ways. In the present review, the role of climate changes in the spread of infectious agents and their vectors is discussed.

Examples of the major emerging viral, bacterial and parasitic diseases are also summarized As a result, the earth will exhibit marked climatic changes characterized by extremer weather events in the coming decades, such as the increase in temperature, rainfall, summertime, droughts, more frequent and stronger tornadoes and hurricanes.

Epidemiological disease cycle includes host, pathogen and in certain cases intermediate host / vector. A complex mixture of various environmental conditions (eg temperature and humidity) determines the suitable habitat / ecological niche for every vector host.

The availability of suitable vectors is a precondition for the emergence of vector-borne pathogens. Climate changes and global warming will have catastrophic effects on human, animal and environmental ec osystems. Pathogens, especially neglected tropical disease agents, are expected to emerge and re-emerge in several countries including Europe and North America." This was reported by The article Climatic changes and their role in emergence and re-emergence of diseases study, published on the Environmental science and pollution research international.

According to the scientific community, the predominant causes are to be found in human activity, due to the emissions into the earth's atmosphere of increasing quantities of greenhouse gases, with a consequent increase in the greenhouse effect, and to other factors always attributable to human activities.

The Kyoto Protocol, signed in November 2009 by 187 states aims to reduce these man-made greenhouse gases, but as we well know, there are few states that fully respect the parameters of the Kyoto protocol.
