Introduction

Emerging infectious diseases are increasing at an alarming rate, posing serious threats to global health and stability. These diseases, often caused by novel or previously rare pathogens, include viruses such as COVID-19, Ebola, Zika and new strains of influenza. Several factors contribute to their rise, including globalization, urbanization, deforestation and climate change. Increased human interaction with wildlife due to habitat destruction has led to the spillover of zoonotic diseases, where pathogens jump from animals to humans. Additionally, rapid international travel allows infections to spread across borders within hours, transforming localized outbreaks into global pandemics. Antibiotic resistance has also accelerated the emergence of difficult-to-treat infections, further complicating disease control efforts [1].

Description

The consequences of the surge in EIDs extend far beyond health concerns. Economies suffer as pandemics disrupt supply chains, reduce workforce productivity and strain healthcare systems. Governments are forced to divert resources toward emergency responses, often at the expense of other critical public health initiatives. Socially, outbreaks fuel fear, misinformation and stigma, sometimes leading to discrimination against affected populations. In response, global health organizations emphasize the need for early detection systems, investment in vaccine research and stronger public health infrastructure. Addressing the root causes of EIDs requires a coordinated, multidisciplinary approach, incorporating environmental conservation, improved disease surveillance and international collaboration to mitigate future outbreaks [2]. Re-emerging infectious diseases are a growing global concern, as infections once thought to be under control are making a resurgence. Diseases such as tuberculosis, measles, cholera and malaria have reappeared in many regions, sometimes in more severe or drug-resistant forms. Several factors contribute to this trend, including declining vaccination rates, antimicrobial resistance, climate change and global travel. In some cases, misinformation and vaccine hesitancy have led to the resurgence of preventable diseases like measles and polio. Additionally, the overuse and misuse of antibiotics have given rise to drug-resistant strains of bacteria, making previously treatable infections much harder to manage. Climate change has also played a role by expanding the range of disease-carrying vectors, such as mosquitoes, increasing the spread of malaria and dengue fever.

Conclusion

Urbanization and population growth further exacerbate the resurgence of infectious diseases. Rapid, unplanned urban development often results in overcrowded living conditions with inadequate sanitation and healthcare access, creating an environment where infectious diseases can thrive. The movement of people from rural to urban areas, along with increased global travel, facilitates the transmission of diseases across regions and even continents. Refugee crises and humanitarian emergencies caused by conflicts or natural disasters also contribute to the problem, as displaced populations often lack access to clean water, vaccinations and proper medical care, making them more susceptible to outbreaks. Another major factor driving the resurgence of infectious diseases is the weakening of public health systems in certain regions. Economic instability, political conflicts and underfunded healthcare infrastructures have led to a decline in disease prevention efforts.
