Global Health Challenges: Tackling Emerging Infectious Diseases

Introduction:

New and resurging infectious diseases constitute a real and present danger to the health of the populations of the world and must be addressed as a high priority and with international cooperation. These diseases, which may be caused by new viruses or pathogens that were hitherto unknown, may result in emergence of pandemics that have severe impacts to the economy, deeper cuts to healthcare facilities and leads to significant rates of deaths. It is therefore important to understand the nature of threat that these diseases present and the corrective action that is right to be taken to prevent the spread hence the health of individuals.

Understanding Emerging Infectious Diseases

EIDs are categorized as those infections which are either newly discovered in a given population or those whose prevalence or geographical spread is either very slow or on an increasing trend. These diseases can originate from zoonotic transfer – diseases that come from animals, mutations of already existing pathogens and pathogens newly introduced to the environment. Some of the EIDs include COVID 19, Ebola, Zika, SARS among others.

Factors Contributing to the Emergence of Infectious Diseases

Since infectious diseases are caused, there are conditions that result to the emergence of the diseases in the society. International linkages cause men to move across the globe, and products such as food to travel from one country to another, a fact that favors easy movement for pathogens. This is the fact that, population increase is accompanied by living density, which is a contagious attribute to diseases. Climate change is also responsible as changes in temperature and weather patterns affects the environment in which these disease causing organisms like mosquitoes thrive and hence leading to spread of diseases like malaria and dengue fever. Also, deforestation and people expansion into wildlife areas lead to the high emergence of zoonotic diseases.

The Role of Surveillance and Early Detection

Prevention and early identification should always form part of any plan to prevent and manage the emerging diseases. The surveillance system should be efficient and effective in early detection of cases of diseases so that appropriate steps can be taken to prevent the outbreak from getting worse. This entails surveillance of disease dynamics, mapping of pathogen trafficking, and efficient detection of disease instances by means of detection tests. This is why international cooperation is a crucial factor in this case, as virus does not stay put within the boundary of a particular country. WHO among other international and regional health organizations, CDC and other institutions have important roles to play in surveillance around the world.

Strengthening Healthcare Systems

Health care delivery system is important in terms of disease prevention and management of new diseases and those that re-emerging. This implies ensuring that the Health facilities are well endowed and that the workforce in place that will meet the outbreak. It is also important to train the healthcare workers in matters concerning EIDs recognition and actions to be taken.

Furthermore, public health care should be advanced, this includes, building up laboratories, medical equipment and supplies, and the research of vaccines and other medicine. For many low and middle income countries, the health care infrastructure is weak and thus requires external assistance to strengthen the ability to combat EIDs.

The Importance of Vaccination and Public Health Measures

All these make vaccination to be among the most prominent solutions when it comes to controlling infectious diseases. The recent increased rate of the development and administration of the COVID-19 vaccines proved that vaccinations can curb the spread of the disease. However and that is where vaccine hesitancy and accompanying and or insufficient vaccine imports present great obstacles. The misconceptions about COVID-19 vaccines must be tackled together with the promotion of vaccines for all population groups particularly those that require it in regions that were most affected.

This is in addition to vaccination, quarantine, social distancing as well as other protective measures like the usage of PPE’s to curtail the spread of EIDs. An important component within these measures is the information campaigns, through which people are explained the necessity to implement certain measures and adhere to them.

Global Collaboration and Research

The prevention and control of new and re-emerging infectious diseases remain a daunting task which must harness multi-sectoral and cross-cutting and international approach towards research. It is imperative that nations work together to share information, property and knowledge with regards to diseases’ identification and vaccines production. Some measures like the Coalition for Epidemic Preparedness Innovations (CEPI) or the Global Research Collaboration for Infectious Disease Preparedness (GloPID-R) have made sure that support of research and development is provided. Indeed, to prevent such calamities in future, there is need to increase research being done on how some of these diseases begin, spread and evolve. 

Addressing the Social and Economic Impacts

Newly identified diseases have several repercussions in societies and different economies. Epidemics are likely to result to massive loss of jobs, increase poverty levels, and contraction of social disparities. The elderly as well as the poor and those with chronic illnesses are the most affected vulnerable socioeconomic groups. Thus, it is essential to consider including the measures on social and economic support in the model of public health interventions. This ranges from; offer of financial support, funding of food supply for the citizenry, and preserve jobs especially in the industries most affected by pandemic. 

Preparing for Future Outbreaks

Therefore, one has to prepare for the future breakouts since they are likely to occur. Health care systems, governments and communities must be strategic in the development of proper preparation plans. These are the issues related to emergency supplies, practice of emergency drills, and the means for conveying information during an emergency. In addition, it is equally important to address some the various causes of the new epidemic threats including ecological pollution and insufficiency of the health systems infrastructure.

Conclusion

Such illnesses are a significant threat especially to the developing world, but with the right strategies, efficient health systems and more research then such diseases can be controlled. All aspects of the outbreak response require support; the surveillance system must be strengthened, vaccination encouraged, international cooperation developed and efforts to control the social and economic impacts accomplished. Thus, people have to work collectively and be prepared to combat these threats as the world faces them and to safeguard global health.
