Black fungus infection and its relationship with the covid-19 disease

The Covid-19 virus has infected different countries of the world since the end of 2019. To date, more than 208 million people have been infected with the disease, and more than 4 million have lost their lives. While efforts to curb the COVID-19 pandemic continue through vaccination around the world, the incidence and mortality continue to rise. Unfortunately, in the fight against the pandemic, COVID-19 patients are also at risk for some secondary infections such as mucormycosis. Mucormycosis, or black fungal disease is a rare and opportunistic infection that can spread fast in people with COVID-19. The action of this fungus is to invade the body's arteries and create clots in them. As a result of the clot, blood flow to the tissues of the body is stopped, and the tissue becomes necrotic or so-called black. Black fungus has made headlines these days during the Covid-19 epidemic, especially in India. Diabetes mellitus and the use of steroid drugs (which are prescribed to treat severe acute respiratory infections) are important risk factors for COVID-19 patients. Due to the opportunistic nature of this infection, early detection of it can reduce the severity of the disease and consequently reduce the mortality of COVID-19 patients.
