How Illinois is responding
The Illinois Department of Public Health, local health departments, and public health partners throughout Illinois, and federal agencies, including the Centers for Disease Control and Prevention (CDC), are responding to an outbreak of respiratory illness caused by a novel coronavirus called COVID-19 that was first identified in December 2019 during an outbreak in Wuhan, China. COVID-19 has spread throughout the world, including the United States, since it was detected and was declared a public health emergency for the U.S. on January 31, 2020 to aid the nation’s healthcare community in responding to the threat. The World Health Organization announced March 11, 2020 that the spread of coronavirus qualifies as a global pandemic.
In addition, Gov. JB Pritzker issued a disaster proclamation March 9, 2020 regarding COVID-19 that gives the state access to federal and state resources to combat the spread of this newly emerged virus.
Watch for symptoms
Reported illnesses have ranged from mild symptoms to severe illness and death for confirmed coronavirus disease 2019 (COVID-19) cases.
These symptoms may appear 2-14 days after exposure (based on the incubation period of MERS-CoV viruses).
- Fever
- Cough
- Shortness of breath
Why are we seeing a rise in cases?
The number of cases of COVID-19 being reported in the United States is rising due to increased laboratory testing and reporting across the country. The growing number of cases in part reflects the rapid spread of COVID-19 as many U.S. states and territories experience community spread. More detailed and accurate data will allow us to better understand and track the size and scope of the outbreak and strengthen prevention and response efforts.
CDC recommendations
Due to widespread transmission in California, CDC recommends expanded and laser focused community mitigation activities to help slow the spread of respiratory virus infections including the novel coronavirus SARS-C0V-2, the cause of the disease COVID-19.
These approaches are used to minimize morbidity and mortality of COVID-19 as well as to minimize the social and economic impacts of COVID-19. Individuals, communities, businesses, and healthcare organizations are all part of a community mitigation strategy.
The focus is on protecting the health care system with expected rise in cases by slowing the spread within the community and focused on protecting the vulnerable members of the community.
