The world is changing fast, and epidemiology is more important than ever for public health. As we enter 2025, many new challenges show why this field is so critical:

🔹 Rising Infectious Diseases – New COVID-19 variants, bird flu, and antibiotic resistance are major concerns. Epidemiologists help track these diseases and control outbreaks.

🔹 Climate Change & Health – Extreme weather, heatwaves, and the spread of diseases like malaria and dengue are increasing. Epidemiology helps us understand and prepare for these risks.

🔹 Technology in Public Health – AI and big data are transforming how we detect and respond to health threats. Epidemiologists now use advanced tools alongside traditional methods to improve health outcomes.

🔹 Non-Communicable Diseases (NCDs) – More people are suffering from heart disease, diabetes, and mental health issues. Epidemiologists study risk factors and create prevention strategies to reduce these problems.

🔹 Health Inequality – COVID-19 showed us that healthcare is not equal for everyone. Epidemiology helps us find the reasons behind these inequalities and guide policies to improve healthcare access.

👉 As someone with a background in public health, I believe we must focus more on disease prevention, health equity, and using data to make better decisions.

    How can we target for “new disease” prevention without experimenting with the new variants of Viruses/Bacteria?
    Secondly, I see Health Equity is a solution which needs to be localised. Our ancestors were knowledgeable but in their local space. As we are in the era of globalisation, the general tendency is to go for generalised approach, which should be avoided. The basis of localised approach definitely is going to be on the accessible Health Infrastructure everywhere. What is your opinion on that?

      Hello Dhruv

      A targeted approach to preventing new diseases does not necessarily require direct experimentation with new viral or bacterial variants. Instead, predictive epidemiology, genomic surveillance, and One Health strategies help identify and mitigate potential threats before they emerge. Advances in AI-driven modeling and big data analytics also enable us to anticipate outbreaks and develop preventive measures without direct exposure to new pathogens.

      Regarding health equity, I agree that localization is key. While globalization has driven a generalized approach, public health interventions must be tailored to regional infrastructure, demographics, and cultural contexts. Strengthening accessible health infrastructure at the local level ensures that epidemiological insights translate into meaningful action. A balance between global coordination and localised implementation is essential for effective disease prevention and health equity.
