One Health approach has gained renewed attention as experts emphasize that viruses do not respect national borders and that equitable access to vaccines is essential for global health security. The topic is highly relevant for UPSC because it connects public health, environment, international cooperation and disaster preparedness. Read more from the daily current affairs archive.

What is One Health approach?

One Health approach is an integrated framework recognizing that human health, animal health and environmental health are interconnected. It promotes collaboration among doctors, veterinarians, ecologists and public health experts to prevent and control disease outbreaks.

Many emerging infectious diseases originate in animals before spreading to humans. Early surveillance across wildlife, livestock and human populations helps detect threats before they become epidemics or pandemics.

Why is One Health approach in News?

The uploaded newspaper article highlights that the world must prepare for future epidemics before they occur and ensure timely, fair and affordable access to vaccines. It argues that international cooperation, research investment and manufacturing capacity are essential to strengthen global health security.

The article also stresses that emerging diseases are becoming more frequent because of increasing human-animal interaction, climate change and global travel. Official guidance is available through the World Health Organization (WHO).

Key Features

The One Health framework supports comprehensive pandemic preparedness.

• Integrated surveillance: Monitors diseases across humans, animals and the environment.
• Zoonotic disease prevention: Focuses on infections that spread from animals to humans, such as avian influenza and Nipah.
• Global collaboration: Encourages countries to share scientific knowledge, vaccines and public health resources.
• Research and innovation: Promotes vaccine platforms, diagnostics and genomic surveillance.
• Equitable vaccine access: Seeks timely and affordable distribution of vaccines during health emergencies.

Challenges

Several obstacles continue to affect pandemic preparedness.

• Unequal vaccine access: Low-income countries often receive vaccines later than high-income nations.
• Weak surveillance systems: Limited laboratory capacity delays outbreak detection.
• Climate change: Expands the geographical range of disease vectors such as mosquitoes.
• Habitat destruction: Increased human-wildlife interaction raises the risk of zoonotic spillovers.
• Limited global coordination: Differences in policies and resources can delay collective responses.

Way Forward

Countries should strengthen disease surveillance, invest in research infrastructure and expand vaccine manufacturing capacity before future outbreaks occur. Coordinated preparedness is more effective than reactive responses.

India can deepen implementation of the One Health framework through collaboration between health, veterinary and environmental institutions while strengthening genomic surveillance and primary healthcare. Further information is available from the WHO.

FAQs on One Health approach

What is the One Health approach?

It is a collaborative framework integrating human, animal and environmental health to prevent and manage disease outbreaks.

Why are zoonotic diseases important for UPSC?

Most emerging infectious diseases originate in animals, making zoonoses important for health security, environment and disaster management.

Why is vaccine equity important?

Timely and affordable access to vaccines helps reduce disease spread, saves lives and strengthens global preparedness against future pandemics.
