“…It has been predicted that climate and environmental changes will affect the geographical distribution of parasites and their human hosts [ 116 – 118 ]. Global warming should facilitate the establishment of parasites and disease vectors into more temperate parts of the world as their optimal temperature for development will shift northwards [ 116 ].…”

The global spread of parasites is unquestionably linked with human activities. Migration in all its different forms played a major role in the introduction of parasites into new areas. In ancient times, mass migrations were the main causes for the spread of parasites while in the recent past and present, emigration, immigration, displacement, external and internal migration, and labor migration were the reasons for the dispersal of parasites. With the advent of seagoing ships, longdistance trading became another important mode of spreading parasites. This review summarizes the spread of parasites using notable examples. In addition, the different hypotheses explaining the arrival of Plasmodium vivax and soil-transmitted helminths in pre-Columbian America are also discussed.

“…The study found that the warming of these regions has led to changes in the distribution and abundance of wildlife hosts and vectors, resulting in the emergence of infectious diseases, such as brucellosis and tularemia. Furthermore, a study by Swaminathan et al [36] highlighted the potential for CC to exacerbate the spread of infectious diseases in domestic animals.…”

“…One of the primary mechanisms is the alteration of the host-pathogen relationship. Changes in temperature, precipitation, and humidity can affect the host's immune system and the pathogen's replication rate, leading to an increase in the likelihood of disease transmission [36]. Another mechanism is the change in the distribution and abundance of vectors and hosts.…”

“…Another mechanism is the change in the distribution and abundance of vectors and hosts. Changes in temperature and precipitation can alter the habitat and behavior of vectors and hosts, leading to changes in the geographical range and seasonality of infectious diseases [36]. For example, the expansion of the geographical range of the Asian tiger mosquito has been linked to CC, which has led to the transmission of several infectious diseases, including dengue fever and chikungunya [37].…”

Several countries are currently evaluating the potential health impacts of climate change (CC), particularly in relation to the complex connections between CC-induced weather fluctuations. China, heavily affected by CC, provides clear evidence of its effects. Previous research in animal sciences indicates that factors like temperature, humidity, precipitation, and wind speed can affect animal epidemics. In China, a major global hub for animal husbandry, these factors pose significant challenges, warranting further investigation into their quantitative relationship with disease outbreaks. This study investigates the influence of these climatic conditions on epizootic diseases in China. In the current study, using data from 278 village-level surveys and daily meteorological data spanning 2012 to 2018, we used a fixed-effect model for analysis. The findings reveal that increasing temperatures and wind speeds exacerbate disease development, while the precipitation anomaly index negatively impacts animal epidemics, with humidity showing minimal influence. Addressing CC’s potential impact on animal disease, governments, organizations, and farmers need to pay more attention to the impacts of climate change on animal diseases and work together to better cope with the impacts through policies, measures, and research.

In this study, in addition to considering the two dominant climatic domains during extreme condition in the study area, temperature and humidity, and determining the correlation and correlation of these two factors with the prevalence of rotavirus gastroenteritis, a statistical model was proposed to predict the prevalence of the disease. Although this research, like many earlier studies, has been based on statistical data for a period of three years, according to its primary objectives, the short-term risk of the disease has been zoned using GIS software, and this point is new. The distinction between the present study and previous studies is considered. Previous studies did not consider the relationship between climate change and gastroenteritis GE. So, the purpose of this study was to investigate the correlation between the number of patients admitted in the hospital with symptoms of gastroenteritis GE and the monthly climatic variables of temperature and humidity of rotavirus, maximum, mean during extreme condition, at least in the city of Ahvaz, in three levels and its suburbs. The results showed a high prevalence of rotavirus infection in children in Ahvaz at low temperature. The maximum rotavirus activity was determined at 13°C. Also, the highest number of patients with symptoms of rotavirus gastroenteritis was observed in autumn and early winter. It is suggested that the results of this study should be considered in determining the timing of vaccination during extreme condition.
