  • Incident: Coronavirus disease (COVID-19) outbreak
  • Location(s): Nationwide; primarily Hubei Province (map)
  • Period: December 2019-February 2020
  • Cases: 60,832 (44,765)

Chinese authorities continue to identify new cases of coronavirus disease (COVID-19) as surveillance and testing are ongoing. Authorities have identified approximately 60,830 suspected cases nationwide, including 44,765 confirmed, according to data through Feb. 12. Approximately 33,370 cases have occurred in Hubei Province, of which 19,500 were reported in Wuhan. Official data indicates daily reported cases have declined overall since Feb. 4, though additional time and data is required to determine whether disease transmission has truly peaked. Risk of infection remains highest in Hubei Province.

The true extent of this outbreak is likely larger than officially recognized. Additional cases will likely be identified in the coming weeks in this rapidly evolving situation.

Background and Analysis
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 is occurring, though it remains unclear how easily the virus spreads between people. Preliminary investigations indicate the course of illness is not as severe as seasonal influenza, nor as contagious. Transmission occurs via contact with respiratory droplets created when an infected individual coughs, sneezes, or speaks.

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, and difficulty breathing, sometimes worsening to pneumonia and kidney failure - especially in those with underlying medical conditions.

On Jan. 30, the WHO declared the ongoing COVID-19 outbreak a Public Health Emergency of International Concern (PHEIC). This indicates that the outbreak requires a coordinated international response, primarily due to the potential for the virus to spread to countries with weaker health systems that would be ill-equipped to contain it. So far, every country that has identified imported cases has contained them appropriately.

The US CDC maintains a "Warning-Level 3" travel health notice due to COVID-19 activity in China. This is the highest of three notice levels, indicating the US CDC recommends avoidance of any non-essential travel to China. Limited access to adequate medical care in affected areas has been reported. This level of notice also advises travelers to practice enhanced precautions: washing hands regularly with soap; avoid contact with sick individuals; and avoid animals (alive or dead), wet markets, and products that come from animals (especially uncooked meat).

Emphasize basic health precautions, especially frequent handwashing with soap and water, or an alcohol-based hand sanitizer if soap and water are unavailable. Avoid close contact with animals (dead or alive), especially at wet markets. 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.
