A thread on travel, Covid-19 and 
.
1. International travel is likely playing a very small role right now. Community transmission is raging, and international travelers are required to quarantine for 14 days.
Interprovincial and regional travel may be a different story.

2. Lab-based PCR testing capacity is severely constrained in the public system. Using it for asymptomatic travelers is not a great idea.

4. We'll miss some cases for sure if we do that. Might be OK, but...
5. As we vaccinate more people, and as winter turns to spring (or, less optimistically, spring turns to summer), travel-related cases will start to form a greater proportion of a smaller number of total cases.

5. To relax restrictions on the general population as quickly as possible, we might actually want to *increase* post-entry testing, monitoring and quarantine requirements over the coming months rather than *decrease* them.
6. As lab-based PCR testing capacity becomes less constrained, we can start to use it for travel. Also, rapid antigen testing can and should be used, not to shorten quarantine but to identify positive cases and trace contacts, especially where people are quarantining with others.
7. The new strain (and the potential for other new strains) also add to the rationale to increase post-entry testing, monitoring and quarantine over the coming months.
End.
End.
