Climate change and vectorborne diseases

CLIMATE CHANGE ANDvectorborne diseases

Did you know that climate change is not just a temperature concern? This article demonstrated that it is also a public health crisis in the making.

The in crease in temperature has a significant connection with vectorborne diseases* because it affects the pathogens, vectors, and hosts. Depending on their adaptability, they could either stop carrying certain pathogens or start carrying new ones.

Lyme Disease

Dengue

Malaria

West Nile Virus Infection

Questions

Conclusions

* We cannot only blame climate change; there are also other factors, such as land-use changes and control measures.

Certain vectorborne diseases have increased in recent decades, including these:

1. What should health policies focus on to prevent the increase of these diseases? 2. According to the article 4.9% of the world's carbon footprint belongs to the healthcare industry, do you think we should focus on reducing the footprint in this industry or in which other industry? 3. Why do you think these diseases are more prevalent in developing countries?

More than 600,000 deaths were attributed to malaria in 2020. In many countries, it is a seasonal disease that responds to rainfall changes, and temperature.

390 million cases occur each year in more than 100 countries. By 2030, the dominant cause of expansion is predicted to be climate change.

It is the most common tickborne illness worldwide. Due to the extended summer season, human-tick interaction increases as well

Between 1999 to 2016, nearly 7 million persons were infected. Air temperature results in a peak incidence of the virus.

CONCLUSIONS

Winston S. Churchill

Conclusion: Our countries are not economically and healthily prepared to deal with these diseases, and the slightest change affects our stability.

Why do you think these diseases are more prevalent in developing countries?

Question

• The poor infrastructures that are not suitable for a correct water management • Lack of a correct vaccination/health program • Climatic conditions: warmer countries are favorable for the spread

Conclusion: A proper health policy must emphasis on the prevention of these diseases, but also should educate people in climate change and how to reduce the impact of their actions in the environment.

What should health policies focus on to prevent the increase of these diseases?

Question

• Education related with the diseases per se, and the vaccination process. • Prevention and early detection • Education not only in the diseases, but also climate change (as a prevention)

I invite all of you to watch this video! It explains some basic concepts to better understand this topic, and discusses other reasons why infectious diseases are increasing. The detection, prevention, and treatment of vectorborne diseases can be controlled with public health policies. However, it is not the only factor to consider, it is also important to control human activities; we should enhance, for example, climate-informed early-warning systems to aware people. Reducing the risk of vectorborne diseases and other health implications requires an immediate adaptation to reduce footprint worldwide.

Conclusion: Even though the footprint of health industry is low, it is still significant. We should not leave it aside, but it also should not be our priority, especially considering that some industry produces more waste.

According to the article 4.9% of the world’s carbon footprint belongs to the healthcare industry, do you think we should focus on reducing the footprint in this industry or in which other industry?

Question

• All industries are important, and we should try to reduce all of them. • It’s not that important to focus on this industry but burning fossil fuels.
