Emerging infectious diseases never end: The fight continues

Area of Science:

• * One Health: Infectious disease emergence at the human-animal-environment interface.
• * Virology: Understanding viral reservoirs and zoonotic spillover mechanisms.

Background:

• * Human society has a long history of being impacted by emerging infectious diseases.
• * Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) is a recent example of a significant viral threat.
• * Zoonotic spillover from animal reservoirs is the primary source of emerging infectious diseases.

Purpose of the Study:

• * To highlight the threat of emerging infectious diseases originating from animal reservoirs.
• * To emphasize the potential for future viral outbreaks due to viruses utilizing human receptors in animals.
• * To advocate for strategies to prevent future pandemics.

Main Methods:

• * Review of historical and current data on emerging infectious diseases.
• * Analysis of viral spillover mechanisms and zoonotic transmission.
• * Assessment of factors contributing to pandemic risk.

Main Results:

• * Viruses in natural reservoirs pose a continuous threat to human health.
• * The presence of viruses capable of infecting human cells in animal hosts indicates a heightened risk of future outbreaks.
• * Interspecies transmission is a critical factor in the emergence of new infectious diseases.

Conclusions:

• * Proactive global surveillance and enhanced wildlife trade regulations are essential.
• * Increased investment in virological research is crucial for pandemic preparedness.
• * Collaborative international efforts are necessary to combat emerging infectious diseases and prevent future pandemics.
