Severity: Warning Alert

Health: Nationwide COVID-19 activity continues in the US during July; transmission increasing again in some states. Maintain health precautions.

  • Alert Begins: 07 Jul 2020 11:37 PM UTC
  • Alert Expires: 31 Jul 2020 11:59 PM UTC
  • Incident: Coronavirus disease (COVID-19) epidemic
  • Location(s): Nationwide (map)
  • Period: January-July 2020
  • Cases: 2,932,596

US authorities continue to report significant increases in COVID-19 transmission among multiple states, though additional states may see further increases in activity following the recent Independence Day holiday on July 4. 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 the states of Arizona, Florida, South Carolina, and Louisiana, with 25 or more new cases per 100,000 people reported in the last seven days. States believed to soon reach their peak transmission include Arizona, California, Florida, Mississippi, North Carolina, Tennessee, and Texas. States reporting consistent overall decreases in new cases during recent weeks include Illinois, New York, New Jersey, and Massachusetts.

At the nationwide level, authorities reported between 40,000 and 58,000 new cases each day since July 1; the highest number of newly reported cases in a single day occurred July 3, with more than 57,700 cases nationwide. However, this does not mean disease transmission has peaked in the US; additional time and data is required, especially as states continue to reopen businesses and reduce their movement restrictions.

Authorities have identified a total of 2,932,596 confirmed and presumptive positive cases of COVID-19, according to US CDC data through July 7. In line with this data, the case count distribution among US states is as follows:

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 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.

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.
