Disease outbreaks can be a significant challenge for communities, placing healthcare resources under immense stress as they look to address high volumes of sick and unwell people. If anything has been learned over the past two decades, humanity faces an increasing array of threats – with few as unpredictable as infectious disease outbreaks.
Understanding why and how outbreaks occur is crucial for medical professionals. For hospital administrators, it can inform them of what equipment they may need at a given point in time. For doctors, it may encourage them to rethink treatment and pivot to options such as telehealth to manage the spread of illness.
Healthcare professionals like those who have completed online nursing programs in Missouri, where the first case of bird flu with no known exposure to an infected animal has occurred, will understand the threat that outbreaks like this present. With no known origin, should healthcare officials be worried about the emergence of a new outbreak?
What is Bird Flu?
For many people, influenza is a part of life. More commonly known as the flu, influenza is a virus that causes an infection in the respiratory system—the parts of the body that help us breathe. While it is a mild illness, it’s highly contagious, spreading rapidly from person to person – and can be quite dangerous, particularly to the most vulnerable in our community, who may be sick or immunocompromised.
While influenza is an illness that affects humans, it is not unique to any particular species. In the animal kingdom, some species have their own flu equivalent. For birds, that is known as avian influenza, also known in scientific terms as H5N1 bird flu.
Avian influenza is an infection that causes respiratory distress in birds and can be much more severe in birds than in humans. While humans have somewhat effective vaccinations for influenza originating in humans, it’s much more difficult to treat illnesses that have jumped from bird to human.
The Challenge of Disease Outbreaks
Disease outbreaks pose significant threats to the population at large. The start of the 2020s saw the emergence of one of the most dangerous pandemics on record – the COVID-19 pandemic, the consequences of which saw more than one million Americans dead from a hazardous, hard-to-treat respiratory illness.
It’s important to recognize that disease outbreaks are more dangerous than physical impacts. Health measures often also impact the economy, leading to people losing work or being unable to work as health authorities work to contain the spread of dangerous illnesses. This can also lead to sustained impacts on the healthcare workforce, with many healthcare workers being forced to care for those who fall victim to a disease outbreak, with highly strained resource pressures.
It’s imperative that disease outbreaks can be monitored, managed, and contained early. This is not only beneficial in managing the challenges that arise when outbreaks occur, but it can also mean the difference between an out-of-control pandemic and a carefully managed threat to the community.
The Recent Bird Flu Cases
In recent years, the U.S. has seen a number of bird flu cases emerge. The first case was detected in a prison inmate working with diseased birds in Colorado. Further cases have been reported in Colorado, as well as Michigan and Texas, bringing the total as of September 2024 to nine.
While bird flu has significantly affected the animal kingdom, human detection has only found mild cases. In fact, the prison inmate who was the first case of bird flu only reported fatigue as a symptom – much less severe than the millions of wild birds that have been culled to reduce the risk of the disease transmitting further.
Should We Be Worried About Bird Flu?
With the lingering threat of past pandemics and their historical impact on lives, such as the COVID-19 pandemic, it’s reasonable to question whether ordinary Americans should be worried about bird flu.
While it may not be a widespread disease, it’s likely only a matter of time before avian influenza evolves into something much more dangerous and transmissible. At that point, bird flu could become a much more significant challenge for the community to deal with.
For disease researchers, monitoring the spread of avian influenza will help them prepare for and identify the best course of action – whether through investment in developing more effective treatments, increased surveillance of high-risk populations, or the culling of birds to reduce the spread of bird flu.
In a recent editorial in the BMJ, experienced epidemiology and virology researchers note that avian flu represents a substantial risk to the community, mainly if it were to mutate into a much more transmissible variant. The risks, the authors note, are clearly there – so it makes sense to begin to prepare for a potential future avian flu pandemic.
Rather than attempting to tackle all the preventative measures individually, an argument is made to persuade decision-makers to implement new strategies. After a decade of pandemics and outbreaks of diseases such as COVID-19, Ebola, and Zika, it makes sense to develop solutions to mitigate the impacts of a future pandemic. Not only does it make economic sense, but it may save lives.
How Can We Make A Difference?
Rather than simply leaving the reader in a state of fear, it’s important to recognize that we can all take steps to contribute to the fight against bird flu. At an agency level, the CDC conducts regular surveillance to monitor the risk it poses to the public. They also recommend a range of protective actions that you and the people around you can take to help protect the public against a potential bird flu outbreak.
Little things, such as observing wild birds from a distance and reporting sick or dead birds, can go a long way toward assisting the CDC in getting a full view of how bird flu might be spreading in the community. Knowing that some things can be done to make a difference can also provide some comfort to the public.
While nine cases in just over two years can seem like a small number, bird flu presents a significant risk to lives and livelihoods. By monitoring this potentially troublesome condition, we may one day prevent another global pandemic from surprising the world.
