A dangerous fungus is making headlines in the US for its alarming ability to invade the human body and destroy tissue from within. Identified as Aspergillus fumigatus, this fast-spreading pathogen has scientists concerned, especially as warmer temperatures could accelerate its growth.
What Is This Deadly Fungus And How Can You Stay Safe From It? Here’s What You Need To Know
Aspergillus fumigatus is a fungus that spreads through the air, releasing microscopic spores known as conidia. These spores are so small that people often inhale them unknowingly. Common in the environment, this fungus can be found in soil, decaying plants, and even household dust.
The National Library of Medicine notes that it grows best at around 37°C and can thrive in warm, moist settings. Remarkably, it can even survive in compost piles at temperatures exceeding 120°F for extended periods.
While most individuals’ immune systems can fight off the spores without issue, some people, especially those with weakened immunity, can develop a severe lung condition known as aspergillosis. In extreme cases, this infection can progress to organ failure and become fatal.
Who Could Become Infected?
Reportedly, those most vulnerable to infection include individuals with weakened immune systems. This includes people undergoing cancer treatment, those with asthma or HIV, individuals with low white blood cell counts, and those recovering from recent illnesses like the flu.
Aspergillus Fumigatus: Deadly Fungus Spreads In The US
Researchers have identified that states like Florida, Louisiana, Texas, Georgia and California face the highest exposure to Aspergillus fumigatus due to warm, humid climates and extensive agricultural activity. Major cities such as New York, Houston and Los Angeles are also reportedly vulnerable because of their dense populations and aging infrastructure.
Health officials note that tracking the fungus is challenging, as aspergillosis is not a reportable disease – its cases, hospitalisations and deaths aren’t officially recorded.
Around 40,000 cases progress into chronic pulmonary aspergillosis, a long-lasting lung infection. Though invasive aspergillosis is rare, it poses a greater threat by spreading from the lungs to organs like the brain, heart and kidneys.
How To Stay Safe From Aspergillus Fumigatus Infection
To reduce the risk of infection, doctors are said to have recommended that people with weakened immune systems steer clear of soil, gardening, and environments with mould.
It’s also advised to wear masks in dusty places and ensure clean, filtered air, especially in hospitals and at home. In response, hospitals in affected states have already started conducting mould inspections and implementing antifungal safety protocols.
