Chiang Mai public health office deputy chief Dr Waranyu Jamnongprasartporn said the two new cases were a Maejo University student living in within the campus and an elderly person in Tambon Nong Han, both of whom were diagnosed for Zika virus on Thursday.
Officials therefore were dispatched to spray mosquitocide and destroy the breeding grounds of Zika-carrier Aedes aegypti mosquitoes at both areas, he said, adding that the control measures would be similar to operations against dengue fever.
