Mexico National Stoplight Health Alert System for Covid-19

NATIONAL STOPLIGHT HEALTH ALERT FOR COVID-19

The four metrics to determine the four colors that indicate risk level from maximum to minimum (Red, Orange, Yellow, and Green) are the trend in numbers of new cases, hospital occupancy trends, current hospital occupancy rates, and the percentage of positive cases.
Under red, only essential activities are allowed. Essential activities include the provision of medical services and supplies, grocery delivery services, operation of grocery stores, restaurant delivery and carryout services, assurance of public safety, maintenance of fundamental economic functions and government social programs, work in critical infrastructure, construction, and manufacturing of transportation equipment. Hotels are limited to 25 percent occupancy for guests working on critical activities. Parks are also limited to 25 percent occupancy.
Under orange, hotels, restaurants, barbershops, open-air parks, and gyms are limited to 50 percent capacity. Markets and supermarkets will operate at 75 percent capacity. Additionally, shopping malls, churches, cinemas, theaters, museums, and cultural events will be limited to 25 percent capacity.
Under yellow, all work activities are permitted. Public space may open on a regular basis, while enclosed public spaces can open with reduced capacity. All activities should be carried out with basic prevention measures. People at higher risk of developing COVID-19 symptoms should continue to take extra precautions.
Under green, all economic and social activities, including school, are permitted while taking appropriate precautions.

The government of every state would declare on a weekly basis the color of the health alert for their cities and municipalities.
