Influenza activity dropped slightly in South Carolina, but remained high enough to make it the nation’s hot spot during week 9 of the 2015-2016 U.S. flu season, the Centers for Disease Control and Prevention reported Dec. 18.
The activity of influenza-like illness (ILI) in South Carolina went from level 9 down to level 8 for the week ending Dec. 12 (week 9), but that kept it in the “high” range, according to the CDC report.
The rest of the United States saw a slight increase in activity, with 15 states at level 2 or higher, compared with 13 the week before. New Jersey had the next-highest level of activity after South Carolina, rising from level 5 last week to level 6, which moved it into the “moderate” range.
Minnesota had the largest increase in ILI activity from the previous week, going from level 1 to level 4, and other states with increased activity were Alabama, Colorado, Georgia, Illinois, Nevada, Tennessee, and Virginia. States besides South Carolina with decreased activity were Arizona, Hawaii, Louisiana, Mississippi, and Texas, the CDC data show.
The proportion of outpatient visits nationwide for ILI – defined as a temperature of 100° F or greater and cough and/or sore throat – was 1.9%, continuing to stay below the national baseline of 2.1%, the CDC said.
Outside of the fifty states, Guam reported widespread activity, Puerto Rico reported “moderate” (level 7) activity, and the District of Columbia and the U.S. Virgin Islands reported sporadic activity, the CDC noted.
