Lyme disease is an infection spread by the bite of ticks that causes more than 300,000 illnesses each year in the United States, according to the Centers for Disease Control and Prevention (CDC). It is the most commonly occurring vector-borne disease and the sixth most commonly reported notifiable infectious disease. A Quest Diagnostics Health Trends study shows Lyme disease surging in states where it has been less prominent than in the past.  Read more

Cardiovascular Health

For the Heart Health Report, Quest Diagnostics conducted a retrospective analysis of data from nearly 80 million LDL cholesterol results reported by its laboratories across the U.S. from 2001 through 2004 for adult patients age 20 years and older. The report identifies a significant and steady decline of approximately 10 percent over a four-year period in average LDL (low-density lipoprotein) cholesterol levels in blood tests ordered on behalf of patients under a physician's care in the United States. However, the decline was slower in women than in men. Read more

Rotavirus Infection

The largest study of rotavirus laboratory data developed since an oral rotavirus vaccine was introduced in the U.S. in early 2006 shows that cases of rotavirus infection have decreased significantly, suggesting the vaccine is preventing infection in infants and young children. Rotavirus is the most common cause of severe, dehydrating gastroenteritis among infants and young children worldwide, and one of the leading causes of emergency department visits, physician visits and hospitalizations of children in the United States.
