Expository Essay
Antibiotics have existed for around a century, and since then, public sanitation has improved hundred-fold. Without antibiotics and modern medicine, millions of people would die from illnesses every year; people do not realize how significant of an impact modern medicine has made to the living conditions of humans during the last few centuries. Before vaccines and medicine, certain people would use voodoo healing and herbs to try to cure illnesses, and that had negligible impact in treating illnesses. During the 1500s, when the bubonic plague ravaged Europe and Asia and killed off about a third of the entire population there. As impossible as it might seem today, there have been some recent developments that have made situations like those above seem like possibilities in the near future.
Recent findings and researches have shown that new strains of bacteria are growing very resistant to vaccines and antibiotics. These new strains, called super bacteria, have been discovered numerous times everywhere around the globe. Super salmonella bacteria have been recently discovered, and while vaccines are able to slow the progress of the bacteria, it is almost impossible for the vaccines to actually stop the super bacteria. A study has shown that the new strain of bacteria is more lethal by more than a hundred fold, and thus the fatal dose of the bacteria has shrunk a hundred-fold. Even a slight exposure to this pathogen would mean certain death, even if one had already gotten vaccinated for this type of micro-organism. If there was a huge outbreak of salmonella like there was just a few years ago, and if the new strain of salmonella participates in this outbreak, it would mean death for hundreds of thousands, because those slight exposures to the bacteria that had little effect on people’s health before will be critical to their health. Another widely known super bacterium is MRSA, or the...
