A Review on the Effects of Global Warming

Abstract

For all facets of human life, including infectious diseases, global warming has significant consequences. The effect of global warming depends on the dynamic relationship between the population of the human host and the infectious agent that causes it. From a human point of view, environmental changes can cause human migration, causing disease trends to move. Host resistance to infections can be reduced by crop failures and famine. Transmission of diseases can be increased by the lack and pollution of drinking water.From sources. Importantly, the current public health system can be weakened by severe economic and political stresses, leaving mankind poorly equipped for unforeseen epidemics.The abundance and distribution of disease vectors will certainly be affected by global warming. They will become more conducive to altitudes that are presently too cool to sustain vectors. Some populations of vectors may spread to new geographical areas, while others may vanish. Among the many vector-borne diseases that are likely to be infected are malaria, dengue, plague, and viruses that cause encephalytic syndromes. Some models indicate that as the earth warms, vector-borne diseases will become more widespread, but caution in interpreting these predictions is required. Clearly, global warming will cause improvements in infectious disease epidemiology.Humanity's ability to respond or adjust depends on the change's magnitude and speed. The outcome would also rely on our ability to detect epidemics early, efficiently control epidemics, provide sufficient care and devote resources to prevention and research.
