    The severe acute respiratory syndrome corona-virus 2 (SARS-CoV-2) is a rapidly emerging virus causing corona-virus disease 2019 (COVID-19) and the global pandemic since the outbreak in Wuhan, China in late 2019[1-2]. Current strategies to protect oneself include getting vaccines, ensuring personal hygiene, using face masks, and practicing social distancing[1]. With constant mutations of the virus, multiple variants of concern (VOC) continue to emerge. The Delta variant (also referred to as B.1.617.2) appears to spread more easily than other variants. It is characterized by increased transmissible, shorter incubation period, stronger pathogenic, faster progression, and higher risks to cause severe illness[3]. It was once the predominant variant of the virus worldwide, which was already predicted by the WHO in July that the Delta variant was expected to be the main strain in the world in the upcoming months[3]. Due to its high infectivity, a rebound in cases has occurred in multiple countries and territories in the past year. ......
