Researchers have observed mutations in some strains that may help the virus spread.
"This is an early warning,” Hibberd said. "Even if these mutations are not important for vaccines, other mutations might be and we need to maintain our surveillance so we are not caught out by deploying a vaccine that only works against some strains."
The study shows that, until January, one group of coronaviruses in China escaped detection because they had a mutation in the genetic region that early tests relied on. More recent tests detect all of the known types of the virus.
