* WHO declares coronavirus outbreak a global health emergency * Philippines set for fifth straight session of losses * Indonesia set to fall over 4% for the week By Arpit Nayak Jan 31 (Reuters) - Southeast Asian stock markets extended losses on Friday after the World Health Organisation (WHO) declared the coronavirus outbreak a global emergency, with Indonesia and Philippines easing over 1% each. The death toll from the virus crossed the 200-mark in China with confirmed cases of infection reported in at least 22 other countries and regions. The WHO director-general on Thursday said the greatest concern was the virus' potential spread to countries with weaker healthcare systems, compounded by cases of person-to-person transfer of the virus outside China.
