Coronavirus disease-2019 (COVID-19) has created a huge impact globally. It created great havoc and claimed many lives. It left a trail on those who survived. Long COVID also known as post-acute sequelae of SARS-CoV-2 infection (PASC) affects 50–70% of people who survive for 3 months or longer after acute COVID-19 infection. It is an emerging syndrome and involves multiple systems due to alterations in cellular energy metabolism and reduced oxygenation to tissues.
