The emergence and resurgence of infectious diseases represent a significant public health threat on a global scale. This issue is particularly pronounced in least developed countries with low and lower-middle incomes, such as Nepal. Despite advancements in healthcare, infectious diseases continue to impose a substantial burden on our society, with a notable increase in deaths attributed to emerging and re-emerging viral diseases and new virus infections compared to seasonal and endemic infections.
The Past Century's Pandemics: A Stark Reminder
The past century has witnessed several pandemics caused by RNA viruses, leading to substantial morbidity and mortality worldwide. These include outbreaks of diseases such as the Spanish Flu, Asian Flu, and more recently, the COVID-19 pandemic caused by the SARS-CoV-2 virus. The devastating impact of the COVID-19 pandemic serves as a stark reminder of the urgent need to address emerging infectious threats. In Nepal, the COVID-19 pandemic has severely strained the healthcare system, highlighted gaps in public health preparedness, and exacerbated existing socioeconomic inequalities.
COVID-19 in Nepal: Impact and Challenges
The COVID-19 pandemic hit Nepal hard, exposing the country's vulnerabilities in dealing with large-scale health emergencies. With limited healthcare infrastructure, inadequate medical supplies, and a shortage of healthcare professionals, Nepal faced significant challenges in managing the crisis. The pandemic resulted in widespread illness and death, disrupted daily life, and caused severe economic hardship.
Healthcare System Strain: Hospitals and healthcare facilities in Nepal were overwhelmed with COVID-19 patients, leading to a shortage of hospital beds, ventilators, and oxygen supplies. The healthcare system struggled to provide adequate care, and many non-COVID-19 health services were disrupted.
Economic Impact: The pandemic led to widespread job losses, reduced income, and increased poverty. Lockdowns and restrictions severely impacted industries such as tourism, which is a significant source of revenue for Nepal. The economic downturn has had long-lasting effects on the livelihoods of many Nepalese citizens.
Education Disruption: School closures and the shift to online learning created a digital divide, with many students lacking access to necessary technology. This has resulted in significant learning losses and widened educational inequalities.
Mental Health Crisis: The prolonged pandemic and its associated stressors have led to a rise in mental health issues, including anxiety, depression, and trauma. The mental health infrastructure in Nepal is not equipped to handle this increased demand for services.
Factors Influencing the Spread of Infectious Diseases
The spread of infectious diseases is influenced by various factors, including socioeconomic conditions, land use, climate, and biodiversity. Vector-borne and zoonotic viruses are particularly sensitive to changes in climate and biodiversity, highlighting the interconnectedness of human, animal, and environmental health. This interconnectedness underscores the importance of adopting comprehensive strategies to manage and mitigate these threats.
Case Study: Monkeypox and COVID-19
One example of a viral zoonotic disease is monkeypox, which has garnered attention due to recent outbreaks reported in multiple countries. The spread of monkeypox underscores the importance of adopting a One Health approach, which emphasizes collaboration between human and animal health sectors to detect, prevent, and control infectious diseases. This approach is crucial for effectively managing diseases that can jump from animals to humans, posing significant public health risks.
Similarly, the COVID-19 pandemic, caused by the SARS-CoV-2 virus, has highlighted the need for a coordinated global response to infectious diseases. The pandemic has shown how quickly a virus can spread across borders, causing widespread illness and death, and underscored the importance of international cooperation in disease surveillance, research, and response.
The One Health Approach: A Path Forward
In conclusion, proactive measures are essential to address the challenges posed by emerging infectious diseases, particularly those caused by RNA viruses. By adopting a One Health approach and enhancing preparedness efforts, we can mitigate the impact of pandemics and safeguard the health and well-being of our communities. This approach fosters collaboration across various sectors, including public health, veterinary health, and environmental health, ensuring a comprehensive response to infectious disease threats.
Taking Immediate Action and Long-Term Strategies
Immediate Actions
Strengthen Healthcare Systems: Improve healthcare infrastructure and access, particularly in outskirts of Nepal. This involves increasing the number of healthcare facilities, sufficient human resource ensuring adequate medical supplies, and training healthcare professionals.
Enhance Surveillance: Implement robust surveillance systems to detect and monitor infectious diseases promptly. This includes improving diagnostic capabilities, increasing testing availability, and ensuring timely reporting of cases with special attention at the border area of Nepal with India and China from where there is high influx of people. Surveillance program should be further strengthen by building capacitated quarantine facilities.
Promote Vaccination: Ensure widespread access to vaccines, including COVID-19 vaccines and other essential immunizations. Public health campaigns should focus on educating communities about the importance of vaccination and addressing vaccine hesitancy. Use of national media like Radio, Television, Newspaper and social media can be implemented for addressing hesitancy.
Provide Economic Support: Offer financial assistance to those affected by the pandemic, including unemployment benefits, business support, and social safety nets. This helps mitigate the economic impact and supports recovery efforts. Effective implementation and monitoring of social security programs endorsed by the government such as health insurance program, The senior citizen's allowance, The disability allowance, Endangered Ethnicity allowance, Bipanna Nagarik Aaushadhi Upachar etc.
Enhance Public Awareness: Increase public awareness about the importance of hygiene, vaccination, and early detection to prevent the spread of infections. Public health messaging should be clear, consistent, and accessible to all segments of the population. This message should be flowed from all the healthcare centers at each local level supported by national media.
Long-Term Strategies
Invest in Research and Innovation: Invest in research to understand emerging pathogens and develop effective treatments and vaccines. This includes funding for scientific research, partnerships with international organizations, and support for innovation in healthcare. Research and collaboration activities should be led by national organizations like Nepal Health Research Council (NHRC).
Foster International Collaboration: Encourage collaboration between governments, health organizations, and communities to address the root causes of disease emergence. Global cooperation is essential for effective disease surveillance, research, and response. Action should be initiated and regulated from the ministry level.
Adopt One Health Approach: Promote the One Health approach, which recognizes the interconnectedness of human, animal, and environmental health. This involves coordinated efforts across sectors to prevent and control infectious diseases. All the stakeholders like ministry of health, ministry of agriculture and ministry of environment should come together in order to make collaborative effort on one health approach.
Improve Environmental Health: Address environmental factors that contribute to the spread of infectious diseases. This includes promoting sustainable land use practices, protecting biodiversity, and mitigating climate change.
Strengthen Health Infrastructure: Build resilient health systems capable of responding to current and future infectious disease threats. This involves investing in healthcare infrastructure, training healthcare professionals, and ensuring access to essential medical supplies.
Promote Education and Technology: Enhance access to education and technology, particularly in rural and underserved areas. This includes expanding digital infrastructure, providing technology for remote learning, and addressing the digital divide.
By taking these proactive steps, we can build resilient health systems capable of responding to current and future infectious disease threats, ultimately protecting global health and ensuring a safer, healthier future for all. The COVID-19 pandemic has provided valuable lessons that should guide our efforts in preparing for and mitigating the impact of future pandemics, ensuring that we are better equipped to handle any public health crises that may arise.
