This study states that Covid illness is a novel irresistible sickness that principally shows as an intense respiratory condition however can likewise cause multiorgan brokenness. Serious intense respiratory disorder Covid 2 (SARS-CoV-2) contamination has been recorded to cause vasoocclusive emergency and intense chest condition in patients with sickle cell weakness (1). We report another possibly significant difficulty of disease in a patient with a typical enzymatic problem.

Glucose 6‐phosphate dehydrogenase (G6DP) inadequacy is a X-connected enzymatic issue that influences 400 million people worldwide and has a high predominance (5%–20%) in African and Asian populaces (2). G6DP catalyzes the development of nicotinamide adenine dinucleotide phosphate (NADPH) (3). NADPH keeps up hemoglobin in the ferrous state by shaping decreased glutathione, which forestalls oxidative harm (3). G6DP lack expands the danger for intravascular hemolysis upon openness to oxidative specialists, for example, fava beans, sulfonamides, and hydroxychloroquine, the subject of clinical preliminaries for people with SARS-CoV-2 disease.

G6PD inadequacy can instigate methemoglobinemia by hindering NADPH-flavine reductase, which forestalls the decrease of methemoglobin.

We report an instance of intravascular hemolysis and methemoglobinemia, accelerated by extreme intense respiratory disorder Covid 2 contamination, in a patient with undiscovered glucose-6-phosphate dehydrogenase insufficiency. Clinicians ought to know about this difficulty of Covid sickness as a reason for blunder in beat oximetry and an expected danger for drug-initiated hemolysis.
