Don't link Mucormycosis / Black Fungus and industrial oxygen

Speculations showed that the rise in black fungus / mucormycosis in post-COVID-19 patients during the second wave of COVID-19 in India could be related to oxygen.


Let it be the oxygen used traditionally in hospitals or industrial oxygen; we believe neither could be the cause.

We logically have two strong points to strengthen our argument: "Don't link Mucormycosis / Black Fungus and industrial oxygen."


1. Pure oxygen is toxic - black fungus cannot grow in industrial oxygen or oxygen cylinders


Neither fungi nor bacteria can live in 100% oxygen, and even humans cannot breathe pure oxygen for more than one or two hours. Likewise, there is no way a tiny fungus, mucor, or black fungus can live in dirty oxygen pipes or oxygen cylinders or industrial oxygen.


Mucor will not grow in oxygen cylinders. Let it be medical oxygen or industrial oxygen.


2. Sporangia cannot grow in water

One more theory around oxygen is that fungus spreads due to unhygienic water used in oxygen flow meters.


The fungus can grow in water in the form of mycelia only, and Mycelia is like a plant without flowering. When fungus grows in water or liquid, it cannot germinate and form sporangia. The fungus cannot release its seeds without sporangia, and Sporangia can grow only on solid substances.


So even if the water used in flow meters is unhygienic and has mucor growing, it cannot cause mucormycosis infection.

Mucormycosis causes

We breathe mucor, the fungus that is responsible for mucormycosis, daily.


We do not need unhygienic oxygen cylinders or dirty water inflow meters to get exposed to it.


It attacks us only when our immunity is down. Unfortunately, COVID-19 can bring down our immunity and increases the risk. The black fungus has been seen in patients who have hardly taken any medication and got self-healed. This gives us more reason to start the medication ASAP and avoid health deterioration.


Mucormycosis or black fungus occurs only when immunity is low

Similar myths involve steroids used for COVID-19 treatment. Steroids can lower immunity only when taken for a long time. For COVID-19, the steroids are given for a short time and will not impact immunity. So, steroids that are offered for COVID-19 cannot be the reason.
