What We Need to Know About Growing Fungal Infections

Warnings in the media are causing concerns about fungi spread, but we can protect ourselves from fungal infections, and vaccines may be available soon.

I wrote about infectious diseases before focusing on viruses and bacteria. In this post, I discuss fungi as they also pose health risks, especially for people whose immune system is weak. Treating fungal infections seems harder than treating bacterial ones due to the tricky nature of fungi.

Recently there has been a significant focus on fungi infections in the media. Some concerns are valid, but the media usually creates sensations for apparent reasons and scare the public for another pandemic. As Dr. John Torres advises, we don’t have to panic but take appropriate cautions individually and collectively.

This story aims to raise awareness by informing my readers using ideas from credible sources. I look at the topic from multiple angles to give the big picture and provide links to essential resources for further research.

As documented in this paper, “Mortality rates from fungal diseases often exceed those for bacterial infections. About 13 million people are at risk of a fatal fungal infection worldwide daily. Over two million die from fungal-related causes yearly, making fungal infection the fifth largest cause of death.”

As a review paper in Nature states, “One challenge in developing new antifungal drugs is the complexity of fungal cells, which are more similar to human cells than bacterial cells. This means that drugs that target fungal cells can also harm human cells, leading to side effects and toxicity.”

Literature in fungi is exhaustive, covering over two million medical records indexed in Pubmed, the National Library of Medicine database.

According to CDC, “There are millions of fungal species, but only a few hundred of them can make people sick.

Fungi can cause many illnesses, like asthma, allergies, rashes, infections on the skin and nails, lung infections (pneumonia), meningitis, and bloodstream infections.

Fungal infections in the lungs can be serious and often cause symptoms that are similar to other illnesses, such as bacterial pneumonia or tuberculosis.”

As informed by CDC, “finding the correct diagnosis can be difficult and cause delays in getting the right treatment. Fungal infections like meningitis and bloodstream infections are less common than skin and lung infections but can be life-threatening.”

The Significance of Fungal Infections

Fungi are living organisms. They harmoniously exist in our gut and skin, but when they are overgrown, they might cause health issues. No one knows how many fungal species cause human disease, but it is estimated to be several hundred.

As articulated in this paper, “four basic conditions necessary to infect humans: high-temperature tolerance, ability to invade the human host, lysis and absorption of human tissue, and resistance to the human immune system.”

Fungi move in the environment and air. Fungal infections can be caused by air, soil, water, plants, and animals. Some fungi are harmless, and others can cause serious infections in humans, especially those with weakened immune systems.

Fungal infections can affect body parts like the lungs, brain, gut, skin, nails, hair, and genitals. Common fungal infections include candidiasis, aspergillosis, cryptococcosis, histoplasmosis, coccidioidomycosis, ringworm, vaginal candidiasis, and fungal nail infections.

Fungal infections are risky for human health because they can be challenging to diagnose and treat. They can cause mild, moderate, or severe symptoms.

However, some fungal infections can be life-threatening, especially in people with weakened immune systems, such as those with HIV/AIDS, cancer, or who have undergone organ transplantation.

My concern is deep fungal infections affecting our brains, lungs, bloodstream, and urinary tract. For example, histoplasmosis can cause serious infections in people with weakened immune systems.

Fungi can produce toxins that damage our cells, tissues, and organs. They can invade the body parts and proliferate, causing tissue damage and inflammation. Fungi can also evade the immune system, making it difficult for the body to fight the infection.

However, despite the health risks, as pointed out in this paper, “fungi attract nowhere near the same interest as viruses, bacteria, and even parasites by health authorities. So, why do we neglect fungal infections? Can we cope with the rise in resistance that’s already increasing mortality from fungal disease in UK hospitals?”

Dr. Mark Ramsdal, quoted in this article, states, “Most of those are superficial things like athlete’s foot, that no one’s particularly bothered about, but there is a core group that causes life-threatening infections, and particularly in susceptible populations such as the very old or young, and those with immune systems that don’t work properly.”

Global Concerns on Rising Fungi Infections

I read many articles about emerging fungi infections after the COVID pandemic. In October 2022, World Health Organization released a first-ever list of health-threatening fungi publicly available at this link.

Dr. Hanan Balkhy, WHO Assistant Director-General, said, “Emerging from the shadows of the bacterial antimicrobial resistance pandemic, fungal infections are growing and are ever more resistant to treatments, becoming a public health concern worldwide.”

Dr. Haileyesus Getahun, WHO Director, stated, “We need more data and evidence on fungal infections and antifungal resistance to inform and improve response to these priority fungal pathogens.”

In February 2023, the Guardian published an eye-opening story titled A growing threat to human health: we are ill-equipped for the dangers of fungal infections, highlighting the growing threat of fungal infections to human health and the lack of preparedness to deal with them.

Another article titled Fungal Infections are becoming more common. Why isn’t there a vaccine? Highlights the key points. It also includes a video conversation with NBC senior medical correspondent Dr. John Torres weighs in on how concerned people should be.

I want to summarize the critical points of these two articles for awareness purposes as they attracted significant interest in social media, cited by many articles, blog posts, videos, and tweets.

Fungal infections are a growing threat, particularly for those with weakened immune systems. These infections can resist many antifungal drugs, making treatment more challenging.

The lack of investment in research and development for new antifungal drugs is a significant concern, leaving the medical community ill-equipped to deal with the growing threat.

One of the main issues is that fungal infections often go undiagnosed or misdiagnosed, leading to delayed treatment and poor outcomes.

The global health community needs to increase awareness of the threat of fungal infections and invest in research and development for new treatments and diagnostic tools.

Prevention strategies such as improved hygiene and antifungal medications are the primary methods for controlling fungal infections.

However, there is a need for vaccination. The development of fungal vaccines is challenging due to the complex nature of fungi and the variety of fungal species that can cause infections.

Therefore, further research and development of fungal vaccines are critical to addressing the growing threat of fungal infections.

Summary of Valuable Perspectives from the Scientific Literature on Upcoming Vaccines for Fungal Infections

As it is impossible to cover thousands of papers in the literature, I discuss the key points of two outstanding review articles within the context of my article as they give us the big picture. They both cover many cited papers.

This review article on nature titled Vaccines for human fungal diseases: close but still a long way to go states, “Despite the substantial global burden of human fungal infections, there are no approved fungal vaccines to protect at-risk individuals.”

I want to summarize this scientific paper with 87 cited references to save time and create awareness. I like the optimistic view of the authors.

This scientific paper discusses the progress in creating vaccines to protect humans from fungal infections. In animal tests, these vaccines have successfully prevented many fungal diseases.

Scientists are also testing them on people at risk of getting these infections. Although there are still some challenges, there is hope that these vaccines will be available for humans in the future.

The paper discusses the challenges and opportunities for developing new antifungal drugs to combat the growing threat of fungal infections.

Even with the availability of antifungal drugs, the burden of life-threatening fungal infections is thought to exceed one million deaths annually.

However, there are promising new approaches to developing antifungal drugs, like targeting specific proteins or pathways in the fungal cell essential for survival and developing drugs that enhance the immune response to fungal infections.

The authors stress the need for increased investment, research, and global attention to fungal infections to drive progress toward developing effective vaccines and antifungal drugs.

Although there is still a long way to go before clinically approved fungal vaccines become available, the authors remain optimistic and highlight the significant progress made in animal studies and human trials.

The article notes that three vaccines have undergone human trials, demonstrating the feasibility of performing clinical trials targeting at-risk populations.

However, the authors also acknowledge the remaining scientific and logistical obstacles that must be overcome. Some challenges are limited funding, a lack of priority for fungal infections, and difficulties conducting clinical trials.

I understand that while significant progress has been made, there is still a long way to go before clinically approved fungal vaccines become available.

The authors stress the need for increased investment, research, and global attention to fungal infections to drive progress toward developing effective vaccines.

I also want to summarize this review paper titled “Why have we neglected fungal infections?” published on Prescriber in September 2022.

The paper states, “Fungal infection is the fifth largest cause of death worldwide, yet fungi attract far less interest from researchers than viruses, bacteria, or parasites. However, the concerning rise in resistant fungi is, at last, focusing more on developing innovative antifungal agents.”

It informs that antifungal vaccines are being developed in mouse studies, and some are in clinical trials. However, there are challenges to overcome before they reach the clinic.

One main challenge is identifying the molecule on the fungal cell wall that triggers protective immunity, as vaccines against fungal pathogens need to trigger primarily cell-mediated immune responses.

People with weakened immune systems, such as chronic lung diseases or recurrent skin and mucosal fungal infections, might be eligible for a vaccination against specific fungal pathogens.

However, how to stimulate weak immune systems with a vaccine sufficiently potent to elicit an immune response is not known.

Despite the challenges, international organizations are paying attention to fungal infections and making an effort to highlight the current needs.

This may change the situation for people with fungal infections in the coming years. The experience gained developing COVID-19 vaccines could yield new ways to immunize against fungal infections.

How to identify risks of fungal infections and lower them

CDC asks ten questions to find out if you are at risk of getting fungal infections. I provide the questions here so you can check the details on the CDC website and discuss solutions with your healthcare providers.

1 — Where do you live and travel?

2 — What types of activities are you doing?

3 — Do you have a dog or cat?

4 — Have you recently taken antibiotics?

5 — Are you taking any medicine that affects your immune system?

6 — Are you receiving chemotherapy or radiation treatments?

7 — Are you living with HIV?

8 — Are you going to be hospitalized?

9 — Have you recently had a transplant?

10 — Do you have symptoms of pneumonia, not getting better with antibiotics?

The critical points of these questions are harmful fungi can be found in air, dust, and soil. We can inhale fungi when gardening, cleaning animal shelters, or visiting caves. Some parts of the world might have them more.

People with immunity problems, like those living with HIV or cancer, and transplant patients are more susceptible to fungal infections.

Fungal infections can have similar symptoms to bacterial infections, but antibiotics don’t work for fungal infections.

Early testing for fungal infections reduces unnecessary antibiotic use and allows for proper treatment with antifungal medicine.

Personal Stories on Fungal Infections

In health communities, I read many articles and personal stories with anecdotes on the challenges of dealing with fungal infections. You can check some personal stories on the CDC website.

A friend of mine had a severe toenail fungal infection, and it took her a decade to finally get rid of it. She tried every possible medication in pharmacies, but nothing worked.

She finally saw a holistic health physician who solved the problem by looking at multiple aspects of health. She even had to change her diet.

I also had a minor fungal infection in a health center swimming pool in my younger years, even though it looked so clean. Fortunately, my family doctor treated it with medication for a few months.

Conclusions and Summary

The growing literature shows that fungal infections are often neglected in research and development globally because most of the burden is in low- and middle-income countries.

There is a lack of definitive data about the scale of the problem. One of the biggest challenges is a lack of affordable diagnostic tests. In addition, healthcare professionals have limited training in low-income countries.

Furthermore, invasive fungal pathogens are opportunistic and infect immunosuppressed people, making them vulnerable to morbidity and mortality.

Therefore, there is a need for increased awareness and investment in research to address the growing threat of fungal infections globally.

Recent news in media and research papers highlights the need for more attention and investment in developing fungal vaccines to prevent and control the rising incidence of fungal infections.

A top writer Susie Kearley posted an informative article to Illumination-Curated titled Next Pandemic Could Be a Fungal Infection, So They’re Working on a Vaccine.

Takeaways

Observing symptoms and obtaining timely support from qualified healthcare professionals is vital. They can diagnose and treat conditions.

The noticeable symptoms are cough, fever, shortness of breath, headache, fatigue, night sweats, itching, joint pain, and sore muscles.

In addition to medical support, we must take precautions to lower the risks of fungal infections via healthy lifestyle choices.

According to the Cleveland Clinic, we can reduce risks with good hygiene. Here is a summary of recommendations to lower the risks of fungal infections.

“1 — Shower after getting dirty or sweaty, and avoid keeping your skin damp.

2 — Don’t walk barefoot in public bathrooms, showers, or locker rooms.

3 — Wear clean and dry cotton underwear.

4 — Take good care of your teeth and mouth.

5 — Follow the directions of eye doctors to use contact lenses.

6 — Keep your nails clean and trimmed.

7 — Only take antibiotics as prescribed to avoid causing a yeast infection.

8 — Avoid sharing personal items like sporting equipment and towels.

9 — Wear protective clothing like gloves, boots, long pants, and long-sleeved shirts when working with soil.

10 — Wear masks if you live where the harmful fungus is commonly found.

11 — If you live in an area with harmful fungus in the soil, wear a mask or stay indoors with the windows closed during dust storms.”

As mold is fungal growth and creates mycotoxins, we must protect our homes and offices from mold, as it can cause serious health issues for people with weak immune systems.

Let’s be cautious and remain optimistic. Humans are much more intelligent than any species on Earth. Everything is figureoutable.
