Dr Taweesin Visanuyothin, spokesperson of the Centre for Covid-19 Situation Administration (CCSA), said the MorChana app records the user's travel information and helps the Department of Disease Control and medics to trace new infections.
The app was first launched in April as a way of safely reopening businesses and services.
It gives users information on their risk from the virus, which is graded into four levels:
• Green for low-risk individuals – no symptoms, no recent travel abroad, no contacts with at-risk people in the past 14 days.
• Yellow for people with less risk – flu symptoms, but no travel abroad, or contact with at-risk people.
• Orange for people at risk – recent travel abroad or contact with at-risk individual(s) in past 14 days but showing no symptoms. People in this group must stay at home for 14 days to monitor symptoms. If symptoms develop, they should go to hospital immediately.
• Red for very high-risk individuals – flu symptoms plus travel abroad or contact with at-risk individual(s) in past 14 days. These people must go to hospital immediately.
The app traces the user’s location to notify them if they enter an area at risk from Covid-19. The location information is not available to other users. MorChana can be downloaded from the App Store or Google Play.
