On March 16, 2020 - the European Commission presented guidelines to Member States on health-related border management measures in the context of the COVID-19 emergency. The aim is to protect citizens' health, ensure the right treatment of people who do have to travel, and make sure control measures do not disrupt supply chain, and essential goods and services remain available.

These guidelines call for coordination at EU level and include:

1. The transport and mobility sector is essential to ensure economic continuity. 
2. Control measures should not undermine the continuity of economic activity and should preserve the operation of supply chains.
3. Professional travel to ensure transport of goods and services should be enabled
4. Member States should preserve the free circulation of all goods.
5. Respect of the specific rules that apply to emergency measures in the aviation sector
6. No additional certifications imposed on goods legally circulating within the EU single market
7. Specific transport nodes (e.g. ports, airports, logistics hubs) should be reinforced as needed.
