Global warming and the associated climate changes are predictable. They are enhanced by burning of fossil fuels and the emission of huge amounts of CO 2 gas which resulted in greenhouse effect.

How might climate change affect the spread of viruses?

The effects of climate change on the spread and on the intensity of infectious diseases have been studied only in the countries along the north-western and western coasts of the Mediterranean Sea, whereas evidence is drastically lacking in the countries on the eastern and southern shores. These regions already face numerous humanitarian crises, from conflicts to natural hazards, and recent geopolitical changes, and climate change is likely to exacerbate the impacts on health. The Mediterranean climate and the proximity to the sea makes it attractive to people, which is resulting in a high rate of conversion of ecosystems for agricultural and other human uses with a parallel reduction in coastal wetlands and forests. As a result, the main constraint faced by the Mediterranean is linked to high population density and population growth, and the expansion of urban areas into peri-urban and rural landscapes. In addition, the risks for public health represented by emerging infections in the region due to the possible expansion of the range of some tropical vectors are an important source of concern widely reported in the media. As a consequence of these ongoing changes, infectious diseases, being contagious or indirectly transmitted via a vector or a reservoir host or both, are expected to be affected.

Climate change, if it occurs at the level projected by current global circulation models, may have important and far-reaching effects on infectious diseases, especially those transmitted by poikilothermic arthropods such as mosquitoes and ticks. Although most scientists agree that global climate change will influence infectious disease transmission dynamics, the extent of the influence is uncertain. This conference session provided an overview of the issues associated with climate change as it relates to the emergence and spread of infectious diseases Figure 1 Figure 2. Two papers set the stage by reviewing data that support or do not support the conclusion that climate change has already influenced transmission of infectious diseases. Other studies, however, point out that in centuries past, vector-borne diseases such as malaria, dengue, and yellow fever occurred regularly in temperate regions in epidemic form during the summer months.

Sub-chapter 2.5.1. Climate change and infectious diseases in the Mediterranean region

Climatic factors influence the emergence and reemergence of infectious diseases, in addition to multiple human, biological, and ecological determinants. Climatologists have identified upward trends in global temperatures and now estimate an unprecedented rise of 2. Of major concern is that these changes can affect the introduction and dissemination of many serious infectious diseases. The incidence of mosquito-borne diseases, including malaria, dengue, and viral encephalitides, are among those diseases most sensitive to climate. Climate change would directly affect disease transmission by shifting the vector's geographic range and increasing reproductive and biting rates and by shortening the pathogen incubation period.

In the coming decades, ecological degradation, rising temperatures, and extreme weather events could intensify the threats to human health posed by viruses. All data and statistics are based on publicly available data at the time of publication. Some information may be out of date.

We know from past epidemics that changes in temperature, rainfall, and humidity can have profound effects on the spread of infectious disease. In the summer of , for example, the southern United States was struck by a catastrophic outbreak of yellow fever, a viral disease indirectly transmitted between people via the mosquito Aedes aegypti. Around , people contracted the disease, and up to 20, people lost their lives.

Global warming has various effects on human health. The main indirect effects are on infectious diseases. Although the effects on infectious diseases will be detected worldwide, the degree and types of the effect are different, depending on the location of the respective countries and socioeconomical situations. Among infectious diseases, water- and foodborne infectious diseases and vector-borne infectious diseases are two main categories that are forecasted to be most affected.

Global Climate Change and Emerging Infectious Diseases

The Effect of Global Warming on Infectious Diseases

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate—disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

Metrics details. Since , the world has been threatened by different waves of emerging disease epidemics. In the twenty-first century, these diseases have become an increasing global concern because of their health and economic impacts in both developed and resource-constrained countries. It is difficult to stop the occurrence of new pathogens in the future due to the interconnection among humans, animals, and the environment. However, it is possible to face a new disease or to reduce the risk of its spread by implementing better early warning systems and effective disease control and prevention, e. In this review, we generally describe some factors related to human activities and show how they can play a role in the transmission and spread of infectious diseases by using some diseases as examples. Additionally, we describe and discuss major factors that are facilitating the spread of the new pandemic known as COVID worldwide.
