Delta variant not more lethal, say experts Bernama PETALING JAYA: While the arrival of the Delta variant of the coronavirus to our shores was expected, there is no evidence to show that it is more dangerous than other strains, medical experts say. “What is dangerous is not being vaccinated, which exposes people to serious illness and death,” Galen Centre for Health and Social Policy founder and chief executive officer Azrul Mohd Khalib told theSun. He said except for evidence that the Delta variant spreads more rapidly among people compared with other known variants, there is no basis to show that it is more dangerous.
