With COVID cases rising again, many travelers are wondering if it's time to cancel their holiday trips. That's a valid question, given this weekend's developments.

It appears to be more transmissible and can more easily reinfect people who have already had COVID, but we don't yet know if it's more dangerous. Here's everything we have so far via the World Health Organization, which admittedly is not much. 

But how will that affect your upcoming holiday trip? And should you cancel now?
