Introduction
The world remains under the influence of COVID-19. While some people are still concerned about the disease and hand hygiene, public health and emergency management experts are already preparing for future pandemics. There have been numerous warnings about viral diseases and potential pandemics. Over the past 20 years, more than 40 infectious diseases have emerged, with articles and white papers highlighting the risks. Potential candidates for the next pandemic include Ebola, SARS, and Monkeypox. When things are going well, there is often a lack of concern. No one was fully prepared for the onset of COVID-19 in early 2019. COVID-19 has disproven several assumptions about pandemics and exposed significant weaknesses in national and global preparedness, detection, and response capacities. Predicting the timing of the next pandemic remains an elusive and critical question.
How to Improve Primary Healthcare to Prepare for Future Pandemics?
-
Recruit, Train, and Prioritize Healthcare Workers: Healthcare workers are essential to a strong healthcare system, especially during the COVID-19 pandemic. Frontline workers, including community health workers, have bravely met challenges like caring for the sick, ensuring vaccines reach vulnerable populations, conducting tests, and maintaining routine healthcare services. To prepare for future pandemics, it is crucial to prioritize healthcare workers by providing training, ensuring they have early access to vaccines for protection, and offering robust financial and emotional support. This enhances their ability to perform effectively and makes the profession attractive to skilled and committed individuals.
-
Establish Effective Surveillance and Response Systems: During the COVID-19 pandemic, outbreaks have occurred worldwide at different times, often involving new and more contagious variants that spread rapidly. Effective testing and reporting systems are crucial to monitor these changes in the virus. This allows health authorities to quickly identify outbreaks or new variants and implement timely measures to control their spread. Community-level surveillance is particularly effective in detecting and responding to these developments swiftly. Going forward, greater investments are essential to enhance testing, especially at the community level. Many low- and middle-income countries still need more access and capacity for testing. These improvements are necessary to expand the ability to detect and contain future outbreaks, increasing the likelihood of more lockdowns, school closures, and business shutdowns. These closures have significant social and economic impacts.
-
Enhance Confidence in Health Services Through Community Health Initiatives: Trust is essential for ensuring people receive the vaccines they need to stay healthy. Developing confidence in healthcare workers, health institutions, and national health agencies is key because they provide critical information. By fostering trust and ensuring that their guidance is evidence-based and respected, one helps to prevent future pandemics.
In addition to trust, effective communication with the public about available healthcare services is vital. People need to know that vaccines are available, where to get them, and when vaccination workers will be present. This is especially important in rural communities where temporary clinics often provide these services.
The “Zwakala” vaccine campaign in South Africa shows the power of combining trust with effective messaging. "Zwakala," meaning "come on over" in Zulu, is an invitation often used among friends. This initiative mobilized community healthcare workers in areas with slow initial COVID-19 vaccination rates. They used local radio, distributed leaflets, and engaged in face-to-face conversations to communicate with the community. This campaign highlights the importance of building trust in public health efforts.
-
Include COVID-19 Vaccines in Routine Immunization Packages: To protect communities from COVID-19, vaccines must be easily accessible at the community level. This can be achieved by including COVID-19 vaccines in routine immunization packages and offering them alongside other vaccines throughout a person's life. This approach requires expanding and strengthening routine immunization and primary healthcare services to serve adults while maintaining childhood immunization efforts.
-
Strengthen Logistics and Supply: Building, delivering, and administering COVID-19 vaccines has been a significant logistical and supply challenge during the pandemic. Vaccinations require more than vaccine doses; essential supplies like protective gear (gloves and masks) are needed to keep healthcare workers safe. Additionally, syringes and cold chain storage are crucial to ensure vaccines are stored at the correct temperature and not go to waste.
The Philippines illustrates the importance of cold chain storage for reaching remote communities with vaccines. The country, comprising numerous hard-to-reach islands and disaster-prone regions, faces unique challenges. For instance, the municipality of Kabugao in the mountains north of Manila experiences frequent extreme flooding and power outages, risking vaccine wastage. Through a partnership between UNICEF and the Japanese government, dozens of solar-powered refrigerators have been provided to communities like Kabugao, ensuring vaccine preservation even during power outages.
How to Prepare for the Next Pandemic?
-
Strengthen Outbreak Identification and Reporting Systems: To effectively handle future pandemics, it is crucial to establish and enhance systems for identifying and reporting outbreaks. For example, during the Ebola outbreak in Guinea in February 2021, a robust surveillance and reporting system was critical in quickly identifying and containing the virus. These systems have been in place for a while and have proven immensely beneficial for global health.
The process works as follows: if a person is infected, a doctor diagnoses the disease based on a watch list maintained by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). The information is immediately reported to national and international health authorities upon confirming the disease.
Healthcare professionals send disease reports globally to organizations like the World Health Organisation (WHO) Global Outbreak Alert and Response Network. This group aggregates data on outbreaks and assesses their pandemic potential. If state health departments do not initially detect an outbreak, governments have emergency management systems to address it.
Quick identification and response are paramount in containing diseases. A rapid global response is possible by maintaining well-funded systems staffed with trained personnel and ensuring continuous training.
-
Identify Leading Threats and Therapies Through Public-Private Collaboration: Experts predict that future pandemics may arise from viruses like coronavirus or influenza. Other potential threats include flaviviruses (for example, West Nile virus), filoviruses (for example, Ebola), and alphaviruses. Organized structures, primarily coordinated by national governments and the biopharma industry, are essential to prepare for such threats.
These entities must create a joint pandemic preparedness system, fostering collaboration between the private and public health sectors to drive innovation. Organizations like WHO and CDC maintain lists of known infectious diseases, guiding continuous efforts to identify and prepare for future pandemics. The biopharmaceutical industry can use these lists to develop therapies in advance.
However, fostering continuous innovation in global healthcare requires balancing private-sector innovation with public regulation, especially in the highly regulated MedTech industry. An interconnected ecosystem where biopharma companies, governments, and NGOs exchange information and align efforts is vital for enhancing readiness.
-
Develop and Distribute New Vaccines Globally: One must learn from past successes to prevent future pandemics. The rapid development, approval, and distribution of the COVID-19 vaccine is a prime example. This unprecedented effort saved countless lives and will be crucial in future pandemics.
Firstly, developing and approving vaccines against unknown threats must be streamlined. This involves rapidly increasing and globalizing vaccine manufacturing and leveraging technology transfers to produce large vaccine volumes.
Secondly, a global distribution network and supply chains are necessary to ensure vaccines reach those in need, particularly in poorer countries with limited healthcare access. According to the World in Data, only 14.4 percent of people in low-income countries have received even one vaccine dose. Addressing this disparity is vital for future pandemic preparedness.
-
Develop, Test, and Use New Technologies: The COVID-19 pandemic spurred numerous technological innovations, from pharmaceutical interventions to wearables and medical devices. These innovations require rigorous testing, regulatory approvals, and clinical studies, demanding time, money, and commitment from global health services.
Medical devices developed for future pandemics must be rapidly adopted and effectively used. Healthcare facilities must prioritize using these new technologies and ensure all medical personnel are adequately trained to use them in real infection scenarios. Practical experience with new technologies is crucial for saving lives in future pandemics.
-
Prepare the Population for Future Pandemics: Guiding and advising two major groups is essential for future pandemic preparedness:
-
Healthcare Personnel: Clinicians, doctors, paramedics, and others handling medical devices must be properly trained. New technologies have significant potential to improve patient outcomes and reduce the strain on healthcare professionals. Ensuring that medical staff are familiar with and can effectively use new equipment and procedures is crucial for saving lives in future pandemics.
-
General Public: Preparing the public should involve clear and consistent messaging based on past pandemic experiences. Effective communication helps individuals understand their role in combating the pandemic. Messages like “flatten the curve” and “behave responsibly” were effective during COVID-19 and should serve as models for future public health communication.
Conclusion
Prioritizing healthcare workers through proper training, early vaccine access, and robust support is essential. Strengthening surveillance and response systems enables timely identification and containment of outbreaks. Public-private collaboration helps identify threats and develop therapies. Expanding vaccine development and distribution globally, especially in low-income countries, is crucial. Embracing new technologies and ensuring preparedness among healthcare personnel and the public will enhance the ability to manage future health crises effectively.
