The expansion of transport networks has a major impact on the global spread of diseases and made the world connected by air, sea, and land easily. There are few downsides of the global expansion of transportation which are infectious diseases, pandemics, vector invasion events and vector-borne pathogen importation (Tatem, Rogers, & Hay, 2006). Within a few months, the COVID-19 extent from Wuhan-China to all parts of the world that shows how easily can a disease sweep the continentals than ever before. Infectious such as the global influenza pandemics, the devastating Anopheles gambiae invasion of Brazil, Plasmodium falciparum malaria cases and recently COVID-19. As the economy grows, human mobility in high-income countries, the volume, and speed of travel are unprecedented. It began with the commercial aviation put people at the risk of new strains of familiar diseases, or from new one; the last five centuries have seen more infectious diseases than ever before (Karlen, 1995).
The history showed that over the past 500 years, the establishment of worldwide transport networks has facilitated pandemics diseases such as Plague, Cholera, Influenza, HIV/AIDS, SARS, Bioterrorism, Malaria, Dengue, and Yellow Fever. The research (Tatem et al., 2006) highlighted that despite the type of transport, the potential of disease emergence and spread can happen very quickly as modern transportation makes the control of infections and quarantine increasingly irrelevant and we must expect more of communicable pandemics. It is suggested to have more predictable information like temporal variations in passengers number and quantifying the relative importance of all types of transports for disease movement.
In the same line, the rapid development and economic growth in central Africa showed the risk of infectious diseases. Despite the positive outcomes from these changes, the region became more vulnerable to future outbreaks (Munster et al., 2018). Relying on the previous outbreak of the Ebola virus, the research mentioned that urban and mobile populations are among the factors which might enable the virus to spread even quicker than before putting the risk of many lives in danger. Researchers predicted that by 2030 Central Africa will use more accessible routes, mining and hydroelectric industries and road constructions which not only affect the ecosystem but also increase the opportunity for new infectious diseases and quicker outbreaks. These are clear signs that rapid and unplanned development can destroy the ecosystem and any demographic-economic changes conspire to cause major outbreaks in both national and international level.
When we talk about the COVID-19 outbreak, we notice how quickly this virus spread globally with a few months of the first case in China. Notwithstanding the previous scenarios with the many outbreaks, we can imply that governments have not prepared properly for such incidents. Bill Gates in his popular talk on TEDx in 2015 discussed that the world is not ready for the next epidemic and that he predicted such an outbreak can kill many if it ignored (Gates, 2015). The questions arise here is that why we don’t pay further attention to the scientific facts that derived from history and experience? Why we need more lives to be taken to establish a stronger foundation to deal with such events? Bill Gates is one of many environmentalists who brought up this topic but yet little efforts have been made. He further talked about how little we invest in healthcare systems while we rapidly grow the industry, and that only the beginning of a series of pandemics if we stay unprepared (TED Connects, 2020).
