Covid-19 Associated Fungal Infections

“Covid-19 fungal infection” likely refers to a specific condition known as mucormycosis, which has been reported as a potential complication in some COVID-19 patients. Mucormycosis, also known as “black fungus” or “zygomycosis,” is a serious fungal infection caused by a group of molds called mucormycetes. It is not directly caused by the SARS-CoV-2 virus itself but can be associated with the weakened immune system and certain treatments used in severe COVID-19 cases. Here’s what you need to know about mucormycosis in the context of COVID-19:

Causes and Risk Factors:

  • Mucormycosis is caused by exposure to molds from the Mucorales order, which are commonly found in the environment.
  • COVID-19 patients who are severely ill and require prolonged stays in intensive care units, especially those on ventilators or treated with corticosteroids, are at higher risk of developing mucormycosis due to a weakened immune system.


  • Symptoms of mucormycosis depend on the site of infection, but it often involves the sinuses, lungs, brain, or other parts of the body.
  • Common symptoms include nasal congestion, facial pain, fever, headache, swelling, dark lesions, and blurred or double vision.


  • Diagnosis of mucormycosis involves a combination of clinical symptoms, imaging studies (such as CT scans), and laboratory tests.
  • Biopsy or culture of infected tissue is often needed for definitive diagnosis.


  • Mucormycosis is a serious condition that requires prompt treatment with antifungal medications, usually amphotericin B.
  • Surgical removal of infected tissue may also be necessary to control the infection.


  • Preventing mucormycosis involves controlling underlying risk factors, especially by avoiding overuse of corticosteroids and other immunosuppressive treatments.
  • Maintaining good hygiene and using sterile water and equipment are important in healthcare settings.

It’s important to note that mucormycosis is still relatively rare and not everyone with COVID-19 will develop this fungal infection. If you have concerns about fungal infections or any health-related issues, it’s recommended to consult with healthcare professionals who can provide accurate information and guidance based on your specific situation.
