Background and Analysis
The US CDC maintains a "Warning-Level 3" travel health notice due to COVID-19 activity in Canada. This is the highest of three levels and indicates US authorities recommend avoiding all nonessential travel. Furthermore, older individuals and people of any age with chronic medical conditions or otherwise compromised immunity should consider postponing nonessential travel, including domestic travel, and take special precautions to avoid becoming ill, especially where sustained community transmission of COVID-19 has been identified. All individuals should monitor their health and limit interactions with others for 14 days after returning from travel.

Older individuals and those with chronic illness are more susceptible to infection and are at increased risk for severe complications. Human-to-human transmission does occur, primarily through respiratory droplets from infected individuals or contact with contaminated surfaces or objects.

Coronavirus disease 2019 (COVID-19) is a viral respiratory disease caused by infection with the SARS-CoV-2 virus. Symptoms occur 1-14 days following exposure (average of 3-7 days). These symptoms typically include fever, fatigue, and dry cough; less common symptoms include headache, diarrhea, loss of taste or smell, reddening of the eyes, skin rash, or discoloration of the fingers or toes. Symptoms may worsen to difficulty breathing, pneumonia, and organ failure - especially in those with underlying, chronic medical conditions.


Emphasize basic health precautions, especially frequent handwashing with soap and water, or an alcohol-based hand sanitizer if soap and water are unavailable. Practice good coughing/sneezing etiquette (i.e., covering coughs and sneezes with a disposable tissue, maintaining distance from others, and washing hands). There is no evidence that the influenza vaccine, antibiotics, or antiviral medications will prevent this disease, highlighting the importance of diligent basic health precautions.
