Our findings suggest that the NAT2*5A genetic polymorphisms plays a significant role in the steady-state concentrations of phenytoin and thereby have impact on toxicity in epileptic patients.

Decades have been witnessing clusters of zoonotic diseases. Human beings at the peak of evolution should not be empowered to alter the environmental homeostasis. Primitive organisms are more rooted to mutate and adapt as per the need or turmoil. Once humans come in the vicinity of these organisms normally residing in their native niche, nature has to pay the cost. Disease outbreaks mostly caused due to unnecessary anthropogenic activities. The threat is that the repercussions are taken for granted or hided wreaking havoc in developing and developed economies leading to an outbreak, an epidemic or a pandemic. The worst influenza outbreak in the world was the 1918 flu that killed nearly 50 million people around the world and modern strains still have an annual death toll in thousands, so the flu is no trifling matter even in a world still facing SARS-CoV-2. Recently, researchers estimated the expected yearly cost of pandemic influenza at roughly $500 billion (0.6 percent of global income), including both lost income and the intrinsic cost of elevated mortality.1
