Children are more vulnerable to infection: 5 infectious diseases caused by changes in the weather


The Science Day activities will be held today, Thursday, hosted by the COP27 Climate Summit, currently being held in Sharm El-Sheikh, which is scheduled to continue until the eighteenth of this month after it started last Sunday.

During the event, Dr. Khaled Abdel Ghaffar, Minister of Health and Population, chaired a discussion session, entitled “Health and Climate Change: The One Health Approach for All,” during which he warned that climate change phenomena increase the transmission of many infectious diseases between people, as billions of people are exposed around the world. The world has many viruses that are essentially environmental viruses.

In the context of this report, we will discuss the most prominent diseases caused by climate change.

According to a report by UNICEF of the United Nations, children are the most vulnerable to diseases that will increase in prevalence as a result of climate change, such as malaria and dengue fever. The organization confirmed that children under the age of five carry nearly 90 percent of the disease burden that can be attributed to climate change.


A major infectious disease that causes death among children under five, and kills up to 2,400 children every day. Childhood deaths from pneumonia are closely linked to undernutrition, lack of safe water and sanitation, indoor air pollution and lack of access to health care – all of which are exacerbated by climate change.

Certainly, it is the same causes of air pollution that cause climate change. About two million children live in areas where air pollution levels exceed standards set by the World Health Organization – forcing them to breathe toxic air and putting their health and the development of their brains at risk.

More than half a million children under the age of five die annually from air pollution-related causes. More of them will suffer permanent damage to their developing brains and lungs.

Heat exhaustion and heat stroke

It is a state of profuse sweating, with an increased heart rate, in addition to the appearance of heat cramps, in the form of seizures that last for a few minutes, and are frequent among children.

It is one of the heat-related diseases related to extreme heat waves, which has become more common in the past years. During the past 16 years, the temperature was the hottest, which increased the incidence of heat-related diseases such as heat exhaustion and heat stroke.

heart disease

Significantly high or low temperatures put pressure on circulation and the functioning of the heart, increasing the risk of heart attacks, strokes, and other cardiovascular diseases.

seasonal allergies

Seasonal allergies are considered one of the resulting and less common diseases due to climate change, as high temperatures and carbon dioxide levels have a significant impact on plants and pollen, so they appear in plants and cause hay fever, and appear in spring, summer and early autumn due to high temperatures.


Climate changes do not only cause organic diseases, but also extend to psychological and mental illnesses. According to a study issued by the Center for Disease Control and Prevention “CDC”, high temperature leads to negative effects on psychological and mental health, and increases rates of depression and problems Other mental health, and higher temperatures may change the way some medications interact with the body, including schizophrenia medications, that affect a person’s ability to properly regulate body temperature.
