ABSTRACT

The outbreak of COVID-19 has brought varying degrees of challenges globally, including full capacity of the medical system, economic recession and patient casualties. While countries are struggling to cope with the COVID-19 pandemic, reports on its variants have increased gradually, with spreading in the population by more powerful infectiousness, faster transmission or more deadly toxicity. Delta is a variant of SARS-CoV-2 originated in India. Infections have been reported in many countries. In absence of specific drugs and limited vaccine protection, there are still challenges in dealing with the spread of Delta variants. Here we will describe the characteristics of Delta variant and related outbreak cases briefly, as well as putting forward the prevention and countermeasures in relation to Delta variant.
