Epidemiology Is The Detective Work Of Disease Control: How Cdc Epidemiologists Helped To Solve The Hiv Mystery
Epidemiologists work like detectives to solve cases of disease outbreaks.
In 1981, the Centers for Disease Control and Prevention team was trying to figure out why young and healthy people in New York and California were getting rare diseases.
To figure out the cause they needed an epidemiologist, Dr.
Michael Osterholm, who started case surveillance.
This involved surveying doctors to get as much information about the case as possible – who was being infected? Where it is appearing? Are there any patterns?
This type of investigation helps with “case definition” – establishing facts about a given case.
For this particular outbreak it was determined that the culprit was a retrovirus; one that attacks the immune system, spread through blood transfusions and sexual activity and most likely originated in sub-Saharan Africa.
This new virus is now known as HIV or human immunodeficiency virus.
For Osterholm’s team in 1980s, understanding an epidemic was like solving a puzzle or doing detective work – collecting data and forming theories, gathering evidence until all pieces fit together.
In this case, there wasn’t anything they could do stop the speedy hyper-endemic spread of HIV but they were able to provide essential knowledge regarding prevention and cures which can be used today.
The Unexpected Roots Of Toxic Shock Syndrome: How A Complex Epidemic Was Solved
The cause of the epidemic that swept across the United States in the early 1980s turned out to be much more complex than any medical professional would have initially believed.
Toxic Shock Syndrome (TSS) seemed to afflict teenage girls, leading researchers to study why this was happening with such frequency.
Epidemiologists like Osterholm noted a pattern between menstruation and the onset of TSS.
To better understand why this was occurring, a case-control study was conducted by looking at responses from both those afflicted and those who had remained healthy during the outbreak.
What they found was shocking – it wasn’t necessarily a single brand of tampon that made people ill; it was a particular type of bacteria that thrived in high-absorbency materials, which just happened to be present in certain tampons more so than others!
This information required critical thinking and trial and error approaches in order to solve the epidemic, but soon enough new rules and regulations were put into place in order to limit any harmful material.
The Most Likely Threat To Humanity Is A Worldwide Pandemic Of A Deadly Infectious Disease
When it comes to the worst-case scenarios for humanity, an infectious disease pandemic is the most likely one.
It may not be as dramatic or eye-catching as a nuclear war or asteroid strike, but the truth is that it can almost certainly have more damaging long-term effects worldwide.
Statistics show that pandemics made up of deadly viruses and bacteria are far more frequent than cataclysmic events like asteroids or nuclear warfare; they are also capable of spreading rapidly and continuing to disrupt life over a much longer period of time.
Such an outbreak could cause famine and other social problems due to our current levels of globalized economies and interconnectivity.
The two main types of infectious agents that could potentially unleash such disasters are viral respiratory infections—such as influenza—which spread quickly, and antibiotic-resistant bacteria, which cannot be stopped with existing medications.
We Are Vulnerable To Pandemics In The Modern World And Must Remain Vigilant And Invest In Vaccines
The modern world is especially vulnerable to a new pandemic due to a variety of factors.
Firstly, population growth of humans and animals has created many potential hosts of infectious diseases which increases the likelihood of new deadly strains emerging.
Additionally, our lives are increasingly interconnected, enabling potential diseases to travel great distances in a mere matter of hours.
Furthermore, with global air travel carrying a huge number of passengers daily, that too represents a significant opportunity for disease transmission.
To protect against such an outbreak it is important to remain vigilant and ensure access to vaccines.
Vaccines can immunize entire populations from illnesses like whooping cough, smallpox and measles reducing the threat these preventable diseases pose.
Finally, further investment into vaccine research and deployment could be key in preventing widespread catastrophe when outbreaks occur in the future.
We Must Be Vigilant To Protect Ourselves From Deadly New Pathogens Created By Dual-Use Research Of Concern
New technologies in the biomedical sciences have enabled researchers to create genetic mutations that give microbes novel traits, leading to various positive applications.
CRISPR technology stands out especially in this field as it is able to cheaply and quickly edit a living species’ DNA sequences.
Scientists are cognizant of this new technology’s potential danger, as the US Senate Armed Services Committee even named gene editing a “global danger” in 2016 given its application in biological warfare.
Biological warfare has been heavily speculated and could potentially come in the form of modified versions of smallpox and anthrax, which would be much more resistant to treatment when compared with their natural forms.
It is also possible that these modified pathogens could be more contagious and spread before symptoms are displayed, leading to catastrophic levels of infection.
In acknowledgement of such dangers posed by developments in biomedicine, governments have developed medical countermeasures such as vaccines and emergency response plans.
However, it may never be enough; the Department of Homeland Security further claims that there is no complete national strategy for biodefense present.
The fact remains that if left unchecked these advancements may lead to an unprecedented pandemic wrought with horrific consequences.
Luck And Hard Work Come Together To Limiting Global Pandemics
It’s surprising to think that a new global pandemic could emerge at any time, from any corner of the world.
In 2014, the Ebola virus erupted in seeledted Guinea and spread quickly, infecting over 10,000 people.
Fortunately two factors contributed to its containment–the fact that it wasn’t airborne so didn’t spread easily, plus the heroic efforts of doctors who helped mitigate its effects.
If even one of these had been different–if it had become airborne or if the population hadn’t sought out medical help–more than 10,000 lives could have been lost and a global pandemic would have occurred.
The same is true for other outbreaks like MERS (Middle Eastern Respiratory Syndrome) which appeared in 2012 and re-emerged in South Korea in 2015.
Its mortality rate was 40%, yet luckily dedicated epidemiologists and health workers were able to contain it.
Even now the viruses still exist around us and may resurface when we least expect them.
Therefore governments should push for more funding towards preventive vaccines research in order to make sure this doesn’t happen again.
Mosquito-Borne Diseases Are A Serious And Growing Public Health Issue
Mosquito-borne diseases are a major health concern for many people, particularly those living in warmer climates.
Recent warming trends have caused an increase in the number of mosquitoes, along with the potential spread of deadly illnesses such as dengue fever, yellow fever, West Nile virus, and chikungunya.
There are now over 3,000 species of mosquitoes that can act as disease vectors and spread these viruses to humans through their bites.
The human population has skyrocketed in tropical parts of the world, creating dense breeding grounds for mosquitoes and putting more people at risk of being bitten.
This has led to an increase in outbreaks of mosquito-borne viruses in various countries and regions.
For instance, the chikungunya virus which was previously restricted to Africa has now been found infecting people in India, Myanmar, and Thailand.
Even Zika Virus which is usually minor has become more serious after it was spread to South America where it infected over a million people.
The challenge remains: how can we effectively prevent the spread of mosquito-borne diseases? Scientists are researching unique ways such as modifying mosquito populations so they cannot host or transmit pathogens.
However, even advancements in modern science cannot guarantee successful prevention of these global health issues – so it’s important to remain vigilant about insect repellents and other precautions when traveling or spending time outdoors!
The Rapid Rise Of Antibiotic-Resistant Bacteria: How To Reverse A Dire Threat To Human Health
Microbes resistant to antibiotics are becoming an increasingly serious problem that must be addressed now.
It is no longer a distant potential threat, but something that has the potential to drastically reduce the effectiveness of medical treatments and engage in a battle between microbes and humans for survival.
Antibiotics is a catch-all term for substances which can kill or slow the growth of harmful bacteria.
These medicines have been very effective at treating diseases ever since their introduction during the 1930s and 40s, but some bacteria have evolved resistance to them over time.
Examples of this include streptococcus pneumoniae, which studies have shown can be up to 40% resistant to common antibiotics, and methicillin-resistant staphylococcus aureus (MRSA), which is more deadly than AIDS and is only growing more dangerous as harmful bacteria become increasingly immune to existing drugs.
Preparing For The Worst: How To Mitigate The Risk Of A Global Influenza Pandemic
When it comes to global pandemics, Influenza presents the most acute risk.
Although most cases of the flu only cause mild symptoms, in some years, such as 1918, it can be much more deadly.
This is due to genetic mutations which occur when the virus is passed between birds, pigs and other animals within these populations.
Scientists have detected 18 different varieties of HA subtypes and eleven NA subtypes that form nearly 200 possible virus combinations with the 1918 H1N1 strain, 1968’s H3N2 strain and two recent strains, H5N1 and H7N9 in China both having a higher mortality rate.
Given that more humans and animals live together in close quarters around the world currently than before, influenza is mutating faster than ever before which is why it has been identified as presenting the maximum risk for causing a global pandemic due to its airborne transmission capabilities.
If a contagious strain were to evolve from one of these viruses, then implementing global strategies would be essential to prevent its spread and reduce the impact on health systems around the world.
We Must Take Bold Action To Prevent A Future Pandemic Disaster
The best way for humanity to avoid a global pandemic is through proactive collective action.
According to Deadliest Enemy, the key message is that by taking decisive steps now, it’s possible to stave off catastrophic illness in the future.
From vaccination investments to international organizations dedicated to controlling infectious diseases, there is no shortage of potential solutions.
Scientists must be adequately funded and supported so they can develop and store new vaccines that are more effective against multiple strains of flu than ever before.
This could require an influx of up to $1 billion – much more than current spending on vaccine research ($40 million).
Furthermore, governments from around the world need to join forces in order to tackle pandemics effectively.
To combat climate change, countries agreed upon the Intergovernmental Panel on Climate Change – a similar set-up should be created for infectious diseases protection too.
Finally, the health and welfare of all living creatures needs to be taken into account: both human and animals are deeply interconnected when it comes to pandemics prevention efforts.
A One Health perspective should thus be adopted, which takes into account how humans and animal populations interact with one another.
All in all, preventing deadly pandemics isn’t a one-person job – it requires unified action from governments, scientists and charities all around the globe if we are to have any chance of avoiding disaster.
The “Deadliest Enemy” provides a sobering look at the reality of global pandemics which makes it all the more important to be prepared.
The book outlines how our interconnected world and growing human and animal populations, together with our ability to create new microbes, puts us increasingly more risk of a potential outbreak.
It is essential that we take action to reduce these risks if we are going to prevent future pandemics.
This involves developing new vaccines as well as enforcing international cooperation efforts that can help us respond quickly and effectively in the event of a disease emergence.
These steps should not be overlooked since they will ultimately keep people safe and prevent costly consequences down the line.
With this in mind, we can ensure that the world is better equipped for whatever threat may come next.
