In the hit video game “The Last of Us,” a deadly fungal infection called Cordyceps has nearly wiped out humanity. While the game is a work of fiction, the fungus itself is actual and can potentially cause serious harm to humans if it mutates and becomes transmissible between humans. In this article, we will explore the biology of Cordyceps and its potential threat to human health.
The Biology of Cordyceps Fungus:
Cordyceps is a genus of fungi that includes over 400 species. These fungi are typically found in tropical rainforests, parasitising insects and other arthropods. Once a Cordyceps spore lands on a host, it will germinate and grow into a filamentous structure that penetrates the host’s body.
The Real-Life Inspiration for “The Last of Us”:
In “The Last of Us,” Cordyceps has mutated to infect humans and turn them into zombie-like creatures. While this may sound far-fetched, the real-life inspiration for the game is the Cordyceps fungus that infects ants and other insects. In nature, Cordyceps spores will infect an ant and take over its body, eventually killing it and using its body as a platform for the fungus to release more spores and infect other ants.
How Cordyceps Infects and Kills Its Hosts:
When a Cordyceps spore lands on a host, it will germinate and grow into a filamentous structure that penetrates the host’s body. Once inside, the fungus will grow and reproduce, eventually killing the host. In insects, the fungus will release spores from the host’s body, infecting other insects and continuing the cycle.
The Potential Threat of Cordyceps to Human Health:
While Cordyceps has not yet mutated to infect humans, there is a real risk that it could do so in the future. The fungus is already known to infect some mammals, including bats and rodents, and there is evidence that it could potentially infect humans. If Cordyceps were to mutate and become transmissible between humans, it could cause a pandemic on the scale of COVID-19 or worse.
What Can Be Done to Prevent the Spread of Cordyceps?
Steps to prevent the spread of Cordyceps and reduce the risk of it becoming a pandemic:
- Monitor and study the fungus to better understand its biology and potential risks
- Reduce habitat destruction and other activities that could promote the spread of Cordyceps
- Develop and stockpile antifungal medications to use in the event of a pandemic
- Invest in research to develop vaccines or other preventative measures
FAQs About Cordyceps and Its Potential as a Pandemic:
Q: Can Cordyceps infect humans?
A: Cordyceps has yet to show to make people sick.
Q: What are the symptoms of Cordyceps infection in mammals?
A: The symptoms of Cordyceps infection in mammals vary depending on the species of an animal infected. The fungus can cause a white-nose syndrome in bats, characterized by white fungus growing on the bat’s nose, wings, and ears. Cordyceps can cause various symptoms in rodents, including respiratory distress, fever, and lethargy.
Q: Is there a cure for Cordyceps infection?
A: There is no cure for Cordyceps infection, but antifungal medications can treat the symptoms. In mammals, treatment usually involves administering antifungal drugs directly to the affected animal.
Q: Could Cordyceps mutate and become transmissible between humans?
A: While Cordyceps can mutate and become transmissible between humans, it is difficult to predict if and when this might happen. However, given the potential for the fungus to cause a pandemic if it were to become transmissible, it is essential to monitor and study the fungus to understand its biology and potential risks better.
Conclusion: Preparing for the Worst
While the idea of a Cordyceps pandemic may seem like science fiction, it is a possibility that we can’t ignore. By studying the fungus and taking steps to reduce the risk of it spreading, we can be better prepared for the worst-case scenario. Investing in research to develop vaccines or other preventative measures in case Cordyceps mutate and become transmissible between humans. The Last of Us may be a game, but the threat of a Cordyceps pandemic is genuine.
