Long-term Care Statistics:  

As of Thursday, Feb 17, there have been a total of 3,057 positive COVID-19 cases involving long-term care residents, and 902 residents of Delaware long-term care facilities have died from complications related to COVID-19.  

Flu Update: 

There were 13 laboratory-confirmed cases reported the week of Feb. 6 – Feb. 12. As of Feb. 12, 2022, the most recent date for which flu statistics are available, there have been 640 laboratory-confirmed cases for the current season. The cases involved 435 individuals from New Castle County, 85 from Kent County and 120 from Sussex County. This number reflects only the number of lab-confirmed cases; the actual number of cases circulating statewide is likely higher as not all people with the flu seek treatment, and many cases are diagnosed through rapid test kits in a provider’s office versus a lab. 

All individuals 6 months and older are strongly encouraged to get vaccinated against the flu if they haven’t already. Flu vaccines are available at pharmacies (including those in grocery stores), participating medical provider offices, Federally Qualified Health Centers (for their patients), as well as Division of Public Health clinics. DPH is also advising the public that the flu vaccine can be administered at the same time as the COVID-19 vaccine.
