What Are the Biggest Health Problems in the World?
World’s Biggest Health Problems
The world is currently facing multiple health challenges. Some of these are old challenges that have never been under control or were only under control in some parts of the world, as well as ones that were once under control but have had a resurgence. And some of them are newer problems that only recently have begun to be studied and addressed.
The causes of the world’s biggest health problems are wide in scope and range from things such as;
– Outbreaks of vaccine-preventable diseases
– Drug resistant pathogens
– Growing rates of obesity and physical inactivity
– Nutrition related diseases and other related health problems
– Growing rates of nicotine and alcohol dependency and other related health
– Environmental problems such as pollution and climate change
– Humanitarian crises
– Epidemics and pandemics
Nine out of ten people in the world breathe moderate to extremely high levels of polluted air every day. It is often considered to be the greatest environmental problem that impacts global health. It is estimated that over 7 million people die prematurely from diseases that can be linked to pollution and poor air quality.
The majority of deaths from air pollution are in low- and middle-income countries where there are high levels of emissions from industry, transportation, agriculture and from cookstoves in homes that use “dirty fuels” fuels derived from tar sands, oil shale and liquid coal that generate high levels of particulate pollution and carbon emissions when they are burned, as well as being destructive to the environment during their lifecycle from production to consumption.
Non-communicable Diseases (NCD)
Non-communicable diseases (NCDs) are responsible for over 70% of deaths worldwide. A non-communicable disease is a disease that is not transmissible directly from one person to another as in, you cannot “catch” a non-communicable disease from contact with someone else. Examples of non-communicable disease include but are not limited to diabetes and other autoimmune disorders, strokes, heart disease, and cancers, to name just a few.
Some of modern medicine’s greatest successes are antibiotics, antivirals and antimalarial medicines. Unfortunately, the viability of these drugs seems to already be running out as the bacteria, parasites, viruses and fungi, develop resistance to these medicines and new strains these harmful organisms and viruses evolve. As the medical community scrambles to come up with new ways to effectively treat antimicrobial related health problems, it is being threatened of a return to a time when things such as upper respiratory infections, tuberculosis (TB) and gonorrhoea, can once again become dangerous and sometimes even deadly.
Epidemics and pandemics of influenza have resulted in large numbers of lives lost during them and unfortunately, the world is going to face another one even though no one knows when or where it will hit or how severe it will become. There are vaccines for the flu but unfortunately there are far more strains of the flu than there can be contained in a vaccine.
