Cordyceps is a fascinating and unique organism used for centuries in traditional Chinese medicine. It manipulates the behavior of its insect hosts, inspiring stories such as the HBO show The Last of Us.
This article will explore the science behind Cordyceps’ ability to create ‘zombies,’ how it differs from other fungi, and the potential threats posed by fungal infections to humans. It will also discuss emerging trends and investment into fungal disease treatments and their potential human impact.

Cordyceps and OphioCordyceps fungi manipulate their hosts to spread spores, which behave in a manner that benefits the parasite rather than the host. These species of fungi have evolved over millions of years to target certain insects specifically, and this evolutionary history has enabled them to infect their hosts with precision. Cordyceps’s neurological effects and manipulation of muscle fibers are poorly understood. However, physical manipulation and chemical attacks on the host may be involved. This has important implications for ethical concerns regarding how we treat other organisms in our ecosystems.
These fungi’s specificity means they are unlikely to jump from one species to another. There are at least 30 known species of OphioCordyceps that parasitize ants alone. This helps us understand why humans are safe from infection because our bodies are too hot for these fungi to survive or multiply within us. However, some mycologists have expressed concerns about harmful fungi becoming more tolerant due to climate change, so it is essential to remain vigilant against potential invasions by fungal pathogens.
Though The Last Of Us depicts a world where a fungus turns people into zombies, the jump of such a zombifying fungus to humans is far-fetched and highly unlikely, given its current form and ecological impact. In reality, parasites like Cordyceps are incredibly fascinating creatures who provide an essential role in keeping our ecosystems balanced – even if they do so through mind control!
Real-life examples of fungi that manipulate their hosts and spread through spores include OphioCordyceps unilateralis, which has astonishingly turned ants into ‘zombies’ in the wild. This species of fungus has an evolutionary history dating back millions of years and has a very specific host specificity. It infects only certain ant species with remarkable precision, indicating its long history of adaptation to insect hosts.
The effects caused by OphioCordyceps unilateralis can be observed in detail. Infected ants stop participating in colony foraging efforts and become hyperactive instead. Eventually, they wander off alone to climb and bite down on a twig or vine before succumbing completely to the infection. The fungus consumes everything inside the ant’s body and uses that energy to sprout a stalk with a fruiting body from its head. The fruiting body then releases spores that spread through air currents or contact with other insects nearby, continuing the cycle.
The ecological impact caused by OphioCordyceps unilateralis is far-reaching because the infected ants behave to benefit the parasite, not the host. In addition, this fungus is just one example of the incredible fungal diversity in nature; at least 30 OphioCordyceps species parasitize ants, though likely many more.
Charissa de Bekker, a mycologist who researches OphioCordyceps, confirms that Cordyceps and OphioCordyceps fungi are real and infect insects in nature.
Infectious fungal diseases represent an emerging threat to human health. Still, fortunately, these types of fungi are unlikely to jump from one species — like insects — to another — like humans — due largely to our high body temperatures being inhospitable environments for them compared with cold-blooded creatures like insects.
Nonetheless, climate change may pressure some fungi to survive in new places, which could open up possibilities for them to adapt to new kinds of hosts or even become infectious among humans given enough time; therefore, monitoring for emerging threats posed by fungal diversity should remain an important area of focus for scientists across multiple disciplines going forward if we want humanity to stay safe from potential pandemics.
Despite manipulating insect hosts, fungi are not likely to jump from one species to another, such as from insects to humans. This is due to the hostile environment of human body temperatures.
However, climate change may lead to a shift in fungal adaptation and an increase in harmful fungal infections. This concerns medical mycologists who believe this could cause large-scale infection events. Furthermore, diagnostic challenges and limited treatments for severe invasive fungal infections add to the concern.
Currently, no vaccines are available for fungal infections; however, this may change with increased research toward developing new vaccines driven by the COVID pandemic.
Vaccine development has been slow due to pharmaceutical companies’ lack of interest and investment; however, government intervention can help drive progress in this area. For example, the Department of Health & Human Services recently announced investments in vaccine development for Candida auris and valley fever – two potential human vaccines expected within the next few years.
The field of vaccinology has made strides forward. However, we still need better diagnostics and treatment options for potential fungal outbreaks to protect ourselves against such an event occurring in real life – unlike what is depicted on television shows like The Last Of Us, where fungus turns people into zombies.
Fungal infections are an emerging threat to human health, with certain fungi exhibiting increased contagiousness, infectivity, and drug resistance. As climate change alters the environment, fungi can evolve and adapt to survive and thrive in new places. This has allowed for the global spread of various species of fungi, many of which are resistant to drugs commonly used to treat fungal infections.
Additionally, the diagnostic challenges associated with fungal outbreaks can make it difficult for medical professionals to diagnose these diseases accurately. In response to this growing problem, vaccine development has become increasingly important. However, due to the lack of interest from big pharmaceutical companies in developing vaccines for fungal infections and the limited number of classes available for treating severe invasive fungal diseases, progress has been slow.
Currently, only one human vaccine is being developed for Candida auris and valley fever; however, there is potential that more will be released in the coming years if further investment is made in this area of research. Additionally, surveillance systems need to be implemented so scientists can better track how emerging threats, such as fungi, spread across populations and regions.
While some species do not pose a serious risk – such as OphioCordyceps unilateralis which does not infect humans – others can present severe complications if left unchecked or untreated by medical professionals. Therefore research on fungal evolution and its environmental impact must continue to stay ahead of any potential epidemics or pandemics caused by fungus in the future.
Cordyceps is a fascinating organism that can significantly alter its hosts.
Fungal infections have become increasingly common in recent years due to environmental changes and globalization.
Approximately 1.5 million people worldwide contract serious fungal infections each year. It is estimated that over one billion people are at risk of a fungal infection in their lifetime.
It is essential for the public to be aware of this emerging threat so they can take preventive measures when engaging with these organisms.
With continued research and investment, treatments for fungal infections may become increasingly available in the near future; however, further action needs to be taken to combat this growing problem effectively.
