Coronavirus has mutated into three variants

The transcript discusses the rapid mutation of COVID-19, leading to three main variants: Type A, B, and C. A study by researchers from the University of Cambridge and Germany identified these types using RNA analysis. Type A originated in Wuhan and spread to the US and Australia. Type B was dominant in Wuhan and East Asia but did not spread widely beyond. Type C was prevalent in Europe, found in early cases in France, Italy, Sweden, and England, but absent in China. The study also traced early infections in Italy to Germany and Singapore.
