The World Health Organization has called for South East Asia to scale up "aggressive measures" to combat the growing coronavirus outbreak. It comes as infections in the region continue to rise, forcing countries to lock down borders and close schools. The WHO's South East Asia region contains 11 countries, almost all of which have now recorded virus cases. It includes Indonesia, Sri Lanka, Thailand, Bangladesh and North Korea. Dr Poonam Khetrapal Singh, Regional Director of the WHO South East Asia region, said on Tuesday that "more clusters of virus transmission are being confirmed".
