Background and Analysis
Additional cases and locations may be added to this list at any time as disease surveillance and testing continues. 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.
