The Delaware Division of Public Health (DPH) reports an increase in COVID-19 cases since the previous monthly COVID-19 update released on April 22, 2022. While COVID-19 cases are increasing in Delaware, hospitalizations and deaths remain significantly lower when compared to the winter surge. DPH continues to encourage Delawareans to get tested if they exhibit symptoms of COVID-19 or have been exposed to someone who tested positive. Although there are no Delaware or federal government mask mandates, individuals are encouraged to mask in public indoor areas in Delaware. Delawareans are also reminded to get boosted to increase their individual protection against COVID-19. Staying up to date with your vaccinations is the best way to ensure your body is prepared to fight against severe cases of COVID-19.

You are eligible for a booster dose if you:

Flu Update: 

DPH reminds the public that flu season is not over.  There were 126 laboratory-confirmed cases reported the week of May 8-May 14. As of May 20, 2022, the most recent date for which flu statistics are available. There have been 2,341 laboratory-confirmed cases for the current season, an increase of 633 since April 22, 2022. The cases involved 1,103 individuals from New Castle County, 518 from Kent County and 720 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. There may be technical discrepancies in reporting numbers week to week due to retroactive reporting of cases.

All individuals 6 months and older may still 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.
