Prevalence of SARS-CoV-2 among community members presenting for testing in Peoria, Illinois from 21 April to 15 May 2020.

Expanding easily accessible community SARS-CoV-2 screening is essential in the response to the COVID-19 pandemic. In this report, we describe the findings from the initial 25 days of a SARS-CoV-2 drive-up and walk-up testing initiative was organized in Peoria, Illinois. Eighty-seven out of 4,073 individuals (2.1%) tested positive for SARS-CoV-2, and 46% of these were asymptomatic at the time of testing. There were ten frontline workers without symptoms consistent with COVID-19 who tested positive, including six that did not report any known exposure to SARS-CoV-2. These results stress the importance and effectiveness of widely available community SARS-CoV-2 testing and suggest a possible benefit to screening of asymptomatic individuals at higher risk for infection.

Hyperosmolar Hyperglycemic State.

Hyperosmolar hyperglycemic state is a life-threatening emergency manifested by marked elevation of blood glucose and hyperosmolarity with little or no ketosis. Although there are multiple precipitating causes, underlying infections are the most common. Other causes include certain medications, nonadherence to therapy, undiagnosed diabetes mellitus, substance abuse, and coexisting disease. In children and adolescents, hyperosmolar hyperglycemic state is often present when type 2 diabetes is diagnosed. Physical findings include profound dehydration and neurologic symptoms ranging from lethargy to coma. Treatment begins with intensive monitoring of the patient and laboratory values, especially glucose, sodium, and potassium levels. Vigorous correction of dehydration is critical, requiring an average of 9 L of 0.9% saline over 48 hours in adults. After urine output is established, potassium replacement should begin. Once dehydration is partially corrected, adults should receive an initial bolus of 0.1 units of intravenous insulin per kg of body weight, followed by a continuous infusion of 0.1 units per kg per hour (or a continuous infusion of 0.14 units per kg per hour without an initial bolus) until the blood glucose level decreases below 300 mg per dL. In children and adolescents, dehydration should be corrected at a rate of no more than 3 mOsm per hour to avoid cerebral edema. Identification and treatment of underlying and precipitating causes are necessary.

Hyperosmolar hyperglycemic state.

Hyperosmolar hyperglycemic state is a life-threatening emergency manifested by marked elevation of blood glucose, hyperosmolarity, and little or no ketosis. With the dramatic increase in the prevalence of type 2 diabetes and the aging population, this condition may be encountered more frequently by family physicians in the future. Although the precipitating causes are numerous, underlying infections are the most common. Other causes include certain medications, non-compliance, undiagnosed diabetes, substance abuse, and coexisting disease. Physical findings of hyperosmolar hyperglycemic state include those associated with profound dehydration and various neurologic symptoms such as coma. The first step of treatment involves careful monitoring of the patient and laboratory values. Vigorous correction of dehydration with the use of normal saline is critical, requiring an average of 9 L in 48 hours. After urine output has been established, potassium replacement should begin. Once fluid replacement has been initiated, insulin should be given as an initial bolus of 0.15 U per kg intravenously, followed by a drip of 0.1 U per kg per hour until the blood glucose level falls to between 250 and 300 mg per dL. Identification and treatment of the underlying and precipitating causes are necessary. It is important to monitor the patient for complications such as vascular occlusions (e.g., mesenteric artery occlusion, myocardial infarction, low-flow syndrome, and disseminated intravascular coagulopathy) and rhabdomyolysis. Finally, physicians should focus on preventing future episodes using patient education and instruction in self-monitoring.
