In addition to the alleged more infective and fatal variant delta, the emergence of particularly lethal fungal infections in between those that have been infected was also reported. Here we comment as while the specific numbers for India, for both new cases and fatalities, were everything but dramatic, with other countries such as the United Kingdom has experienced much worse outcomes, the incidence of black fungus minimally affected the COVID-19 fatalities. First better care, and the use of intravenous antifungals, and then the use of better therapies in the early stages of infection to prevent more serious outcomes, reduced the burden of this fungal infection. It was reported in May 2021 of COVID-19 variants spreading rapidly in India, linked to a surge in infections [1, 2] . There was evidence of one variant being more transmissible and slightly better at evading immunity [1, 2] . The rise in fatalities, still small if considered relative to the population when compared to countries such as the United Kingdom, made the international headlines. Casesper-million peaked at 283.534 about May 9, 2021, fatalities-per-million peaked at 3.00 on May 22, 2021 [3] . The United Kingdom had 881.31 on January 9, 2021, and 18.46 on January 26, 2021, respectively [3] . A comparison of the COVID-19 outbreak in India and the United Kingdom is proposed in Fig. 1 It was reported as the fatalities of India were also caused by bacterial and fungal infections [2, 4, 5] . It was previously found that 33% of critical COVID-19 patients in India had bacterial infections [5] . It was then reported as an epidemic of ''black fungus'' cases [2, 4] was a further driver of fatalities. Mucormycosis [6] [7] [8] [9] , a normally rare infection, has a huge case-fatality rate of*50% [10] , much larger than the about 1.15% case-fatality-rate at the time for COVID-19 in India. Very few cases were reported of an extremely rare, but even more deadliest ''white fungus'' [4] . Bacterial infections are everything but uncommon also in the United Kingdom. Different is the case of mucormycosis, practically unknown in the United Kingdom. There have been thousands of cases of mucormycosis affecting COVID-19 patients in India, also after recovery. The growing number of cases are linked with the steroids being used to treat COVID-19, with diabetics or severely immunocompromised individuals, such as cancer patients or people with HIV/Aids, at particular risk [2, 4] . The excessive use of steroids for COVID-19 patients was likely the cause of the upsurge of this otherwise very rare fungal disease. The infection originates from the reduced capacity to naturally clear the spores because of the COVID-19 infection and reduced immune response as a result of the steroids used to limit the immune system's overreaction to infection [11] . It was argued that immunosuppressive drugs and supportive oxygen favor the biosynthesis of ergosterol which is a key component of Images from [3] fungal cell membranes [12] . As previously written, the infection was particularly dangerous in patients with diabetes [10, 13, 14] , with specific explanations elusive. The numbers of black fungus infections (or COVID-19 infection) of India must be put in the correct perspective, as the absolute numbers in a country of 1366 M people may appear incredibly high in countries with a dramatically smaller population such as the United Kingdom. On May 28, 2021, there were recorded almost 12,000 cases of the ''black fungus'' infection in India [11] , 27.37 M cases of COVID-19, and 315,235 COVID-19 fatalities. In 2019, there were about 7.27 deaths per 1,000 inhabitants in India, or 9.93 M. The major causes of death in India in 2019 in order of relevance were Ischemic heart disease, Chronic obstructive pulmonary disease (COPD), Stroke, Diarrheal diseases, Neonatal disorders, Lower respiratory infect, Tuberculosis, Diabetes, Cirrhosis, Falls, Road injuries and Self-harm [15] . While the black fungus infection does not affect in a sizeable way the case-fatality rate of COVID-19 infection, that is not the main cause of fatality in India, still, it was certainly a reason for relative concern [16] , not only for India but also for other South Asian countries. Prevention was the first measure to adopt [9, 16] . This required improving hygiene in hospitals, as well as in residential settings. The use of steroids to prevent cytokine storms in COVID-19 patients was then rationalized [16] for what is possible. More care was exercised especially with those in the risk categories (for example those with diabetes) [16] . Then, better treatment should be provided, including appropriate intravenous antifungal products, leaving surgical intervention to attempt to resolve the worse cases [16] . Measures such as the adoption of the extremely effective Uttar Pradesh Ivermectin-based COVID-19 home treatment kit [17, 18] , which dramatically affected the number of daily new cases and fatalities, contributed to a reduced need for steroids and therefore a reduced incidence of Black fungus infection presently negligible. The use of an antiviral such as Ivermectin in early stages [19] [20] [21] , coupled to one antibacterial, plus vitamins and minerals, has been the best therapeutical approach against COVID-19 infection and indirectly against the Black fungus infection. Thus, while the numbers of black fungus infections in India considered not in isolation, but within the context of the normal mortality of a country of 1366 M people, were not particularly dramatic, the issue was properly addressed by the Indian health authorities, same as the COVID-19 infection issue, not certainly in a way worse than the way the pandemic was addressed in the United Kingdom. There is a clear need to urgently addresses the current downfalls of the media subjectively attributing excellency or disvalue to the proponents of health policies including pharmaceutical and non-pharmaceutical measures, no matter which are the objective outcomes of these policies.
