Question

Why do you think there are more diseases now that spread quickly and have a global impact?

Answer 1

there are more disease now that spread nore quickly and have global imact the main reason behind this is globalization which has led to fast changing environment, over use of resources including human resources, habits that favour fast daily life like eating fast foods, skipping meals, restricting to the desk job lack of excercising. Besides this ncresaed mutations arise due to changes in environment which in turn is the result of genetically modified crops, new irrigation methods(use pesticides and fertilizsers which pose carcinogenic effects), industrialization, and the list continue...

Globalization, the flow of information, goods, capital, and people across political and geographic boundaries, allows infectious diseases to rapidly spread around the world. The spread of diseases across wide geographic scales has increased through history. Early diseases that spread from Asia to Europe were bubonic plague, influenza of various types, and similar infectious diseasesModern modes of transportation allow more people and products to travel around the world at a faster pace; they also open the airways to the transcontinental movement of infectious disease vectors. For example West Nile virus reached the United States via “mosquitoes that crossed the ocean by riding in airplane wheel wells and arrived in New York City. With the use of air travel, people are able to go to foreign lands, contract a disease and not have any symptoms of illness until after they get home, and having exposed others to the disease along the way. The virus was found on crew members of ships and trains, and all the infected employees spread the virus everywhere they traveled. As a result, almost 50-100 million people died of this global transmission.

With porogress in medicine, many vaccines and cures have been developed for some of the worst diseases "plague, syphilis, typhus, cholera, malaria" . however as the evolution of disease organisms is rapid, even with vaccines, there is difficulty providing full immunity to many diseases. Since vaccines are made partly from the virus itself, when an unknown virus is introduced into the environment, it takes time for the medical community to formulate a curable vaccine. The lack of operational and functional research and data, which provide a quicker and more strategized pathway to a reliable vaccine, makes for a lengthy vaccine development timeline. Even though frameworks are set-up and preparations plans are utilized to decrease the Covid-19 cases, a vaccine is the only way to ensure complete immunization. Some systems like the Immunization Information System, provide preliminary structure for quick responses to outbreaks and unknown viruses.These systems employ past data and research-based on modern world vaccine development successes. Without vaccines, the global world remains vulnerable to infectious diseases.

Globalization has enhanced the spread of infectious diseases across the globe, also the risk of non-communicable diseases by transmission of culture and behavior . It is important to target and reduce the spread of infectious diseases in developing countries. However, addressing the risk factors of non-communicable diseases and lifestyle risks in the South that cause disease, like consumption of tobacco, alcohol, and unhealthy foods, is important as well.

Even during pandemics, it is vital to recognize economic globalization in being a catalyst in the spread of the coronavirus. Economic factors are damaged by increased global lockdown regulations and trade blockades. With increased interconnectivity among economies and the globalization of the world economy, the spread of the coronavirus maximized the potentiality of global recessions. The coronavirus pandemic caused many economic disruptions, which caused a functional disconnect in the supply chain and the flow of goods. As transportation modes are relevant to the spread of infectious diseases, it is important to also recognize the economy being the motor of this globalized transmission system.
