    Mucormycosis in covid 19 patients in India is in raise in second wave of covid 19 pandemic

    Dear Editor,
    Mucormycosis is a fatal fungal infections that mainly affects people who are on medications for other health problems that reduces their ability to fight for environmental pathogens.India is a known to have high burden of mucormycosis cases especially in those with unconrolled type 2DM and prevalence of mucormycosis has gone this time up to 2.1times to 3 times during covid 19 pandemic in India. This may be termed as Covid Associated Mucormycosis or CAM.Prvalance of CAM amongst the covid-19 patients is 0.27/%,and in ICU or in CCU is 1.6% when they are treated with steroid and to those in patients who had high level of blood sugar due to covid- 19 or have high level of ferritin.Occasionally in patients with unconrolled DM ( whose neutrophils functions is impaired in diabetic and those who have neutropenia or altered NL ratio as in covid 19 , as primary defence of mucormycosis is done with neutrophils attached with hyphae ) or in hematlogical malignancies, or in hemopoietic stem cells transplant or in solid organ transplant or in patient's with vercanzole therapy or with immunomodulatory drugs or other immunosuppressive drugs develop fatal mucormycosis.
    In covid 19 wards or in SARI wards mucormycosis may develop due to 1) That NL ratio is altered 2) from treatment of steroid dexamethasone injection 3) use of tocilizumab therapy 4) uses of Immunomodulatory drugs like Baricitinib ,tofacitinib and usually found in later part of treatment ....

    Incidence of mucormycosis is in raise in India due to covid-19 in second wave of2021

    Dear Editor,
    Mucormycosis is a fatal fungal infections that mainly affects people who are on medications for other health problems that reduces their ability to fight for environmental pathogens.India is a known to have high burden of mucormycosis cases especially in those with un controlled type 2DM and prevalence of mucormycosis has gone this time up to 2.1times to 3 times during second wave of covid 19 pandemic in India. This may be termed as Covid Associated Mucormycosis or CAM.Prvalance of CAM amongst the covid-19 patients is 0.27/%,and in ICU or in CCU is 1.6% when they are treated with steroid and to those in patients who had high level of blood sugar due to covid- 19 or have high level of ferritin.Occasionally in patients with unconrolled DM ( whose neutrophils functions is impaired in diabetic and those who have neutropenia or altered NL ratio as in covid 19 , as primary defence of mucormycosis is done with neutrophils attached with hyphae ) or in hematlogical malignancies, or in hemopoietic stem cells transplant or in solid organ transplant or in patient's with vercanzole therapy or with immunomodulatory drugs or other immunosuppressive drugs develop fatal mucormycosis.

    Do emerging SARS-CoV-2 variants cause early and greater immunosuppression which may contribute to co-infection with mucormycosis?
    • Ashutosh Kumar, Assistant Professor All India Institute of Medical Sciences, Patna

    Dear Editor,
    This case report presents a very important accompaniment of COVID-19 illness which has currently raised up to epidemic scale in India (1). There is sound empirical evidence that unsupervised use of steroids, uncontrolled blood sugar and existing immunosuppression in COVID-19 may predispose the patients to the opportunistic mucormycosis infection (2,3). Surprisingly, co-infection with mucormycosis were rarely reported during the first wave in India, although the pandemic had spread extensively in the country. There is a possibility that sudden and massive increase in the number of cases and consequently collapsing of the health system in the country may have contributed in the rise of mucormycosis cases in various ways, including multiple iatrogenic causes, such as no proper sterilization of the medical equipment and the hospital wards. Wearing unclean face masks carrying fungal spores and other unhygienic practices might have also contributed in rise of the cases (4). However, no significant reporting of mucormycosis cases during the first wave of COVID-19 pandemic poses some valid questions, whether the newer SARS-CoV-2 variants, particularly that of B.1.617 lineage which are being suggested as the driver of the second wave in India (5), are causing greater and/or early immunosuppression than the wild strain. Emerging evidence suggest that the new SARS-CoV-2 strains, including that of B.1.617 lineage, may have increased virulence (6,7). Although, certai...
