Climate changes cause serious diseases that are transmitted to humans through insects

Weather of Arabia - Climate changes, lack of biodiversity, and environmental degradation all affect the human response to diseases and vectors of infection, such as mosquito bites. Researchers stress the importance of global cooperation to prevent diseases whose strength increases due to climate change, and they focus on the importance of achieving environmental balance to confront these challenges.

Insects can smell us

Scientists describe types of mosquitoes that are vectors of dangerous infectious diseases that have contributed to the spread of epidemics during the last decade, and that they can smell our scent . British researchers at the University of Lancashire, in cooperation with the Global Health Group, affiliated with the Barcelona Technology Center, are studying how insects, including mosquitoes, adapt to climate change. The research focuses on humid and hot tropical regions where climate change contributes to the spread of diseases and viruses.

According to scientists' statements, understanding insect breeding places and their environment can contribute to predicting the extent of the spread of diseases, including dengue fever in particular, in the world. Dengue fever and other diseases such as Chungunya and Zika virus, which the World Health Organization warned about due to climate change, appear and are still widespread in more than 100 countries globally, posing a real threat to Asian countries, including Bangladesh, which witnessed the largest wave of infections. dengue fever in the world recently.

Unprecedented temperatures in Bangladesh

In a report issued by the World Bank in 2021, it was noted that Bangladesh witnessed an unprecedented rise in temperatures by half a degree Celsius, along with an increase in the summer period, which greatly contributed to the spread of dengue fever at an accelerated pace.

The beginning of the era of climate disasters

With researchers declaring the beginning of the era of climate disasters, experts confirm that developing joint global strategies to manage and control diseases, and protect poor communities most vulnerable to these diseases, can play an important role in reducing the incidence of epidemics or even eliminating them completely.

British scientists have warned that the warm weather that the British Isles have recently witnessed may contribute to the stabilization of some dangerous tropical diseases in the country. Recent studies have shown the discovery of new species of mosquitoes that had not been previously observed.

In the county of Kent in southern England, scientists are taking high alert measures in anticipation of the arrival of strains of mosquitoes in the country, as warm weather gradually promotes their growth and reproduction in the United Kingdom. Currently, scientists are concerned about the emergence of a new type of mosquito that has not yet settled in the country, but has begun to arrive.

In this context, Director of the Department of Medical Entomology, Jolyon Medlock, said: “We have observed the appearance of this type of mosquito six times, all in southeast England, and as climate change and warmer weather continue for longer periods, conditions become more suitable for their reproduction on each visit to the area.” "The country."

Tiger mosquito

The tiger mosquito has spread in Europe since it was first spotted in Italy in 1990, and today it breeds in 13 countries. According to scientists' estimates, it is expected to settle in the United Kingdom within 50 years if its current rate of arrival into the country continues.

Professor of Tropical Diseases at the University of London, Oliver Brady, points out that the tiger mosquito transmits serious diseases, although deaths as a result of infection are rare. However, its treatment requires a long period in the hospital. Brady confirms that their presence in large areas of the world indicates that simple diseases may turn into historical epidemics.

On the other hand, the European Center for Disease Control and Prevention, which belongs to the European Union Health Authority, warned that “changing climate conditions increases the risk of diseases transmitted by these types of mosquitoes, which are currently increasingly spreading in Europe.”

The center pointed out that these types of mosquitoes are known as vectors of viruses such as chikungunya, Zika, dengue, West Nile, jaundice, and others, and their spread is accelerating in the north and west of the European continent.

Blood-sucking mosquito bites can transmit several serious diseases. Among these diseases:

• Dengue fever.
• Malaria.
• West Nile virus.
• Yellow fever.
• Zika virus.
• Chikungunya.
