Fungi are single or multicellular organisms that can be found in multiple habitats. Fungal species that grow in soil are major decomposers that live on dead and decaying matter. These fungal species are important for recycling different elements in nature. Some fungal species are parasites that cause diseases in plants and humans.

Recently, with the increasing cases of COVID-19, a surge in the cases of black, yellow, and white fungus was reported. The initial outbreak of black fungus or Mucormycosis was reported in many patients, followed by white and yellow fungus. Experts are aware of the lethal consequences of fungal co-infections in COVID-19 patients with immunocompromised conditions. Thus, it is important to maintain high levels of hygiene and cleanliness while treating the patients infected by opportunistic fungal species.

The fungal spores are ubiquitous in our environment but do not harm humans under healthy conditions. They pose a threat to people whose immune systems are weakened due to infection and the use of drugs. The fungal infections caused by opportunistic fungal species can commonly lead to cases of hospitalization and death.

The Indian government, under "Mission COVID Suraksha," channelized the power of public-private partnerships to increase the production of COVID vaccines and antifungal drug Amphotericin B to combat COVID and related fungal infections.
