Southeast Asia is facing a strain of the new coronavirus that the Philippines, which faces the region’s largest outbreak, is studying to see whether the mutation makes it more infectious.

The strain, earlier seen in other parts of the world and called D614G, was found in a Malaysian cluster of 45 cases that started from someone who returned from India and breached his 14-day home quarantine. The Philippines detected the strain among random Covid-19 samples in the largest city of its capital region.

The mutation “is said to have a higher possibility of transmission or infectiousness, but we still don’t have enough solid evidence to say that that will happen,” Philippines’ Health Undersecretary Maria Rosario Vergeire said in a virtual briefing on Monday.

The strain has been found in many other countries and has become the predominant variant in Europe and the U.S., with the World Health Organization saying there’s no evidence the strain leads to a more severe disease. The mutation has also been detected in recent outbreaks in China.

There’s no evidence from the epidemiology that the mutation is considerably more infectious than other strains, said Benjamin Cowling, head of epidemiology and biostatistics at the University of Hong Kong. “It’s more commonly identified now than it was in the past, which suggests that it might have some kind of competitive advantage over other strains of Covid-19,” he said.
