  • Incident: Coronavirus disease (COVID-19) epidemic
  • Location(s): Nationwide (map)
  • Period: January-September 2020
  • Cases: 6,047,692
  • Transmission: Respiratory (coughing, sneezing, speaking)

US authorities report the nationwide coronavirus disease (COVID-19) case count surpassed 6 million Sept. 1. While overall transmission is decreasing, community transmission continues throughout the country and the risk of infection remains high regardless of destination in the US.

At the nationwide level, authorities reported an average of roughly 41,200 new cases per day during late August; this represents a decline since peak transmission was observed in late July. However, the resumption of in-person education in some states, as well as easing of business and movement restrictions, will likely create new localized outbreaks of infection in areas where transmission was previously decreasing.

Authorities have identified a total of 6,047,692 confirmed and presumptive positive cases of COVID-19, according to US CDC data through Sept. 2. The incidence rate of COVID-19 (cases per 100,000 people, a better indicator of infection risk than case count alone) indicates the risk of infection is currently highest in Louisiana, Florida, Arizona, New York City, Mississippi, Alabama, and Georgia). In line with this data, the incidence rates are as follows according to US CDC data through Sept. 2:

  • New Hampshire


Incidence rate fewer than 537 cases per 100,000:

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. 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 (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.
