Fungal infections have long been overlooked as a major global health threat, but new research reveals these silent killers are becoming even deadlier. A comprehensive study published this week in The Lancet estimates that fungal infections caused 1.7 million deaths in 2020 – more than malaria or tuberculosis. Shockingly, global mortality from fungal diseases has nearly doubled over the past decade.

Fatal Fungi: An Underestimated Threat

Fungal pathogens are eukaryotic organisms that can cause potentially life-threatening infections, particularly in immunocompromised patients. However, the global burden of fungal diseases has been poorly quantified until now.

“Fungal infections are a silent pandemic, growing globally largely unnoticed,” said lead author Dr David Denning, President of the Global Action Fund for Fungal Infections.

The new Lancet study analyzed data on fungal infection deaths from over 100 countries. Researchers found a massive undercounting of fungal mortality in previous analyses:

Year Previous Fungal Infection Death Estimate New Study Estimate
2010 ~900,000 deaths 1.5 million deaths
2020 No prior global estimate 1.7 million deaths

“This landmark paper demonstrating that fungal infections are a major cause of death worldwide is a wake-up call to governments and health agencies,” said Denning.

Fungi Find New Victims

Over the past ten years, the countries with the highest fungal infection mortality rates have remained consistent – India, Nigeria, Democratic Republic of Congo, Tanzania, and South Africa. However, the prevalence has exploded in some regions.

East Asia saw a 364% increase in annual fungal deaths, largely driven by population growth and aging. Mortality also rose significantly in Europe and Central Asia. Experts warn climate change may expand areas suitable for pathogenic fungi.

“Fungal pathogens are adapting to warmer temperatures…This, coupled with increased human exposure to fungi, creates the environment for possible pandemics,” said Dr Toni Gabaldón of the Institute for Health Science Research in Barcelona.

Double Threat: Drug Resistance & Misdiagnosis

Part of the reason fungal infections have become more lethal is the lack of effective treatments. These complex eukaryotic microbes can mutate to resist antimicrobial drugs. A new fungicide additive for crops is also generating mass resistance.

However, even more deadly is misdiagnosis, meaning life-saving antifungal therapy is not given in time. “Most people who die of a fungal infection never knew they had one,” explained Denning. Better diagnostic tools are desperately needed.

Some key risk factors for fungal infections include HIV/AIDS, organ transplants, chemotherapy, and lung conditions. With more immunosuppressed patients worldwide, fungi have found fertile ground.

Long-Term Outlook: Adapt or Perish

Looking ahead, experts agree much more research funding and global health focus must target fungal diseases. “The figures highlight the essential need for improving medical infrastructure in vulnerable countries,” urged Dr Gabaldón.

Increased surveillance is critical to detect outbreaks and new pathogenic strains early. Developing novel classes of antifungal treatments is also a pressing priority with resistance on the rise.

Without action, experts predict fungal infection deaths could hit 6 million per year by 2060. Denning concludes: “either we adapt now or potentially face catastrophic loss of life.”
