  • Location(s): Nationwide (map)
  • Period: January-April 2020
  • Cases: 554,849

Summary
US authorities have identified 554,849 confirmed and presumptive positive cases of coronavirus disease (COVID-19) according to US CDC data through April 13. These figures may change or fluctuate as additional data becomes available during this rapidly evolving situation. At this time, approximately 45-percent of all confirmed cases have occurred in the states of New York and New Jersey.

States with widespread transmission indicate COVID-19 activity is not confined to particular areas of that state; people have been infected with the virus, but how or where they became infected is not known, highlighting the importance of diligent use of basic health precautions, including hand and respiratory hygiene.

Background and Analysis
Additional cases may be added to this list at any time as disease surveillance and testing continues. Significant increases in case counts are expected as laboratory test results become available. The total case count includes individuals on repatriation flights and those returning from cruise ships; adding together the state totals will not denote the overall total without these numbers. 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.

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. 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.

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.

Advice
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.
