Apart from a high population of at‐risk individuals, multiple factors have precipitated an increment in mucormycosis cases in the country following the COVID‐19 pandemic. These include increased use of corticosteroids, immunosuppression following the viral infection, prolonged stays in the intensive care unit and sub‐optimal laboratory testing available in the country. This article aims to assess the potential implications of a mucormycosis epidemic on a healthcare system already strained under the COVID‐19 pandemic, and provides subsequent recommendations to weather the dual challenge of two deadly pathogens. virus (HIV), AIDS, or a history of chronic respiratory diseases, asthma, and liver disease. 3, 4 The clinical presentation of primary cutaneous mucormycosis may have a gradual or insidious onset. Eschars are the most prevalent cutaneous finding, but it also includes targetoid lesions, tender nodules, ulcers and purpuric lesions. Secondary cutaneous mucormycosis manifestations are more frequent than primary manifestations. They usually result from a rhinocerebral or disseminated infection, and have an acute onset with high mortality. 5 According to global epidemiological surveillance, infections of mucormycosis have been on the rise, with a particular increased incidence in Asian countries. 3 Although there is no thorough data available to assess the exact burden of fungal diseases in Pakistan, the country reported high rates of mucormycosis infections (14/100,000) even prior to the onset of the COVID-19 pandemic. 6 Corresponding to the trend in its neighbouring country, India, 4,7 several cases of mucormycosis, also known as black fungus-related deaths, are now being identified among COVID-19 patients at various hospitals across Pakistan. 8 The use of steroids leaves the COVID-19 patients immunocompromised, and the viral infection, added to a prolonged admission in intensive care in severe cases provides ideal conditions for mucormycosis to infect patients. Furthermore, it was reported that an increasing majority of COVID-19 patients took corticosteroid medications especially during the second COVID-19 wave in Pakistan, which explains the recent increment in mucormycosis cases in the country. 9 Additionally, severe COVID-19 disease leads to increased levels of pro-inflammatory markers, including IL-1, IL-6 and tumor necrosis alpha, and decreased levels of CD4 interferon-gamma, CD4 and CD8 cells; which augments the chances of microbial infections including mucormycosis. Usage of low-quality industrial-grade oxygen cylinders, unclean and humid environment of the hospital facility, tap water in humidifiers and antibiotic overuse may also trigger the mucormycosis infection. 5 The diagnosis of cutaneous mucormycosis is difficult because of its non-specific findings. It mainly relies on polymerase chain reaction and fungal culture. Since it is a highly fatal disease, rapid diagnosis and multidisciplinary measures are key to improve mortality rates. 10 However, as with many other developing countries that are experiencing concomitant infectious epidemics in addition to COVID-19 such as Zika virus in Brazil, Yellow Fever in Africa, the diversion of medical supplies and personnel to COVID-19 will prove to be a considerable challenge for Pakistan in prioritizing mucormycosis surveillance, diagnosis and management alongside a robust COVID-19 response. [11] [12] [13] The The risk of cutaneous mucormycosis associated with COVID-19: A perspective from Pakistan struggle of developing countries against cutaneous mucormycosis is further compounded due to suboptimal laboratory facilities and lack of expertise, which is a major hindrance in keeping accurate disease records. To successfully contain the outbreak of mucormycosis in the country, the first step is the development of context-specific management guidelines in order to deter the side effects of the antifungals required for its treatment. Second, the use of corticosteroids in COVID-19 patients must be exercised with extreme caution and in accordance with WHO's recommendations, which specifically warn against their use in mild, moderate or asymptomatic COV-ID-19 infections. 14 Since a delay of mere 6 days in the inception of treatment for COVID-19 associated mucormycosis results in a twofold increase in the mortality rate, 15 laboratory facilities should be enhanced and rapid diagnostic kits must be expedited. It is also crucial to reinforce the public health capacity in Pakistan and improve the physician to patient ratio which currently stands well below the WHO standards. Infection control practices must be updated in a stringent capacity in all healthcare facilities to provide protection against both mucormycosis and COVID-19. A handful of population-based studies have been conducted to calculate the prevalence of mucormycosis in the western world. However, the findings from such studies are not relevant in developing countries, as the high-risk groups and interventions differ considerably. In developing countries, a rise in the incidence of mucormycosis can be attributed to the excessive burden of diabetes mellitus, while in developed countries, it is commonly found in immunosuppressed individuals or those receiving transplants. The advent of latest risk factors and etiological agents, such as post-tuberculosis, chronic renal failure, and stay in ICU, warrants population-based studies in countries like Pakistan with a high incidence of vulnerable populations to understand the epidemiology of the disease. 3 Thus, the added burden of highly fatal re-emerging infectious diseases such as mucormycosis puts the public health security at significant risk. In the wake of the COVID-19 pandemic, it is crucial to expand laboratory-testing capacities, invest in robust technologies to improve epidemiological surveillance, and institute awareness and preventive measures to alleviate the burden on our health services.
