The impact of rising global temperatures on our health

The impact of rising global temperatures on our health

 

◇ Rapid increase in heat-related illnesses

Climate change affects the occurrence of diseases in various ways. As temperatures rise, the incidence of heatstroke and heat exhaustion increases. This is especially deadly for the elderly over 65, pregnant women, children, and those with chronic illnesses.

According to a 2022 study, it is estimated that over 60,000 people in Europe died from heatwave-related stress.

In our country as well, due to the early heatwave with daytime highs exceeding 30°C since last week, the number of heat-related illnesses has increased compared to the same period last year.

 

A total of 72 heat-related illness cases were reported, including one estimated death in the first week of June. The same period last year had 54 cases, representing a 33.3% increase.

◇ Increase in mosquito population... Malaria alert issued

Vector-borne diseases transmitted through insects like mosquitoes are also closely related to climate change.

Malaria and dengue fever are representative vector-borne diseases. The incidence of both diseases is increasing as their mosquito habitats expand due to climate change.

According to the World Health Organization (WHO), it is predicted that the population living in malaria risk areas will increase by 100 million by 2030 due to climate change.

Our country is also not a safe zone for malaria.

 
On the 19th, the Korea Disease Control and Prevention Agency conducted an investigation into the density of malaria vector mosquitoes. The results revealed that in the malaria risk areas of Korea (Seoul, Incheon, Gyeonggi, Gangwon), the increase in vector mosquitoes has reached the warning level. It was confirmed that this year's warning was issued about a week earlier than last year. This is due to the highest temperatures being approximately 2°C higher than the average and the previous year.

Malaria infection symptoms include chills, fever, and sweating. These symptoms recur every 48 hours, and in severe cases, are accompanied by headache, diarrhea, and vomiting. Symptoms can appear anywhere from as short as 7 days to as long as 2 years after being bitten by an infected mosquito.

Malaria can be completely cured through medication treatment because there is an effective cure. However, if not treated perfectly, it can relapse within two years.
