Background and Analysis
Additional cases and locations may be added to this list at any time as disease surveillance and testing continues. The US CDC maintains a "Warning-Level 3" travel health notice for the global COVID-19 outbreak. This is the highest of three levels and indicates US authorities recommend avoiding all nonessential travel.This indicates older individuals and people of any age with chronic medical conditions or otherwise compromised immunity should consider postponing nonessential 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, infants, and those with chronic illness are more susceptible to infection and are at increased risk for severe complications. Human-to-human transmission can occur, though it remains unclear how easily the virus spreads between people.

On March 11, the WHO declared the ongoing coronavirus outbreak a pandemic. This shift in posture from an earlier briefing indicating the WHO would no longer use the term "pandemic" to describe disease transmission is reflective of the current COVID-19 global impact. Per the March 11 statement, "Describing the situation as pandemic does not change WHO's assessment of the threat posed by this virus. It doesn't change what WHO is doing, and it doesn't change what countries should do."

Coronavirus disease 2019 (COVID-19) is a viral respiratory disease caused by infection with the SARS-CoV-2 virus (previously known as 2019-nCoV). Symptoms occur 1-14 days following exposure (average of 3-7 days). These symptoms include fever, fatigue, cough, difficulty breathing, sometimes worsening to pneumonia and kidney failure - especially in those with underlying 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.
