Bioaerosols are present everywhere around us, either on surfaces or in the air. Depending on their nature, these bioaerosols have positive or negative impacts on our bodies. Our immune system always creates a balance in our health system in response to these bioaerosols. If our body’s immune system is compromised for a while, it could have many severe health complications. A good example is in patients who recovered from COVID-19 during the COVID-19 pandemic. During treatment, many drugs like dexamethasone, tocilizumob, itolizumab, and steroids were extensively used that suppressed the immune system, resulting in many fungal infections. In this review, we summarise the various studies carried out throughout the globe regarding fungal infection, including Mucormycetes (black fungus), Candida spp., Aspergillus fumigatus, and pneumocystis jirovecii. The patient disease history and treatment details were also examined so as to develop the risk of mortality. Populations with other pre-existing diseases such as diabetes and asthma are more vulnerable to infection. These infections spread at a very high rate and have a high risk of mortality in patients who have recovered from COVID-19. Earnest attention is needed regarding the treatment procedure of COVID-19 patients and for the follow-up of recovered patients. Here, we suggest some treatment methods that will help prevent infection in patients who have recovered from COVID-19 or in immunosuppressed bodies.
