Studies confirm that climate change affects public health and food security

Because human health is linked to environmental health and safety. Therefore, climate change and its impacts on various sectors pose a direct and indirect threat to human health.

Suggested Topics

Dr Noha El-Sayed Ibrahim from the Department of Microbial Biotechnology at the Biotechnology Research Institute says that one of the areas where climate change poses the greatest threat is to human health, as it contributes to the spread of disease and rising temperature has increased the number of months in which malaria has spread since the 1950s. And the increase in areas that provide an incubation environment for cholera transmission and the ability of viruses to spread, including the viruses that cause dengue fever and Zika, have increased worldwide..

The phenomenon of climate change affects global health and the environment, for example, deforestation leads to an increase in carbon dioxide in the atmosphere and forces bats and other animals that can carry the disease to come into contact with humans, which was most likely the reason for the emergence of this coronavirus (coronavirus). In the long term, global warming is likely to bring mosquito-borne tropical diseases, such as West Nile virus, Zika, and malaria, to northern latitudes.

Without effective primary health care, the response to shocks will be reactive, expensive and not always effective. The immunization system, which must be extended to reach all children, can serve as a basis for establishing primary health care. With community relationships, supply chains and health registries already in place, it becomes much easier to deliver interventions Other health benefits that can benefit individuals and society as a whole, such as nutritional supplements and malaria prevention programs.

reference studies

indicate Dr Amal Saad Hussein – Member of the National Council on Climate Change and former Dean of the Environment and Climate Change Research Institute – National Research CenterTo the results of the Institute’s research, which show the link between climate change and public health, and recommend the importance of producing predictive maps of diseases associated with climate change, of providing preventive and curative means, and of disseminate the knowledge and training of medical personnel and researchers in the fields of health, to find solutions to the health problems expected with climate change.

A study was carried out to know the impact of climate change on public health, and to draw up health maps of infectious diseases sensitive to climate change and to the adaptation strategy. Climate change has been proven to occur in some Egyptian governorates. New places.

A study of the temporal trend of bladder cancer rates resulting from schistosomiasis was published in various Egyptian governorates, and its relationship to climate change during the period 1995 to 2005. The results showed that the average temperature of the air is increasing in all governorates, and that the number of days when the maximum temperature is 45°C or more has been increased in Upper Egypt.

Bladder cancer schistosomiasis rates have decreased significantly in most urban areas, thanks to preventive and curative measures provided by the Ministry of Health and Population, while there have been no change in rates in border governorates, but cases have emerged in the red region. Sea and Sinai, as a result of the relocation of farmers from Delta lands to new areas in search of increased income due to erosion of farmland areas, due to rising sea level sea ​​and the increase in its salinity due to many factors, which have negatively affected the quality of its productivity, and have prompted some families to migrate to urban or border areas, to work as construction workers in search of growing family income.

A landmark study has been published dealing with the impact of climate change on parasitic liver diseases in Africa, as it leads to the spread and reproduction of infection vectors, such as insects or intermediate snails, and also shows the effect of climate change on altering the pathological map of liver health problems, in terms of infectious diseases and their spread and pollutants that cause non-infectious liver diseases, such as liver cancer and hepatotoxicity .

In addition to evaluating biofilms for pond drainage, dust accumulated on air conditioning filters and public hospital floors, pathogenic and non-pathogenic types of bacteria were isolated, which were commonly found in various locations in hospitals. and in public places, in addition to discovering the presence of Aspergillus and Penicillium fungi of common fungal species, in the case of air and dust, and the accumulation of dust on air conditioning filters and surfaces of soil, and therefore the increased use of air conditioners carries the risk of exposure to these microbes, if there is not regular maintenance and adequate cleaning of the filters.

Food safety

Noted Dr Ahmed Noah Badr – Department of Food Poisons and Pollutants – National Research CenterClimate change threatens food production worldwide as it affects ecosystems. Certain types of weeds, insects and pests benefit from higher temperatures, increasing their ability to damage crops and create financial hardship for farmers.

Rising temperatures can alter exposure to certain pathogens and toxins such as: Salmonella, Campylobacter, Vibrio Especially in seafood, as well as the spread of fungi that cause mycotoxins in agricultural food crops.

Mycotoxins are considered to be one of the major food-borne hazards, which also have serious implications for food safety. They are toxic metabolites produced by different species of fungi that contaminate many staple food crops and cash crops .When crops are exposed to stressful conditions, such as high temperatures, drought, they become more susceptible to fungal infections, which can lead to the exclusion of certain food products from the export market.

The most promising solutions globally were forecasting models, through which the negative effects expected in the future regarding the safety and security of food production can be monitored, in a way that ensures the possibility of intervention. through the development of adaptation strategies commensurate with the expected risks.
