Although spring has officially begun in the Northern Hemisphere last week, which marks the beginning of a much better weather, at least 10 states in the United States are still battling with a pronounced level of influenza-like illnesses (ILI) incidence.
Latest influenza monitoring data from the Centers for Disease Control and Prevention (CDC) showed that nationally, outpatient cases of influenza-like illnesses remained at an elevated level. For the week 11, which covers March 13-19, the most common type of influenza in the US was the influenza A (H1N1) pdm09 virus.
The report, however, noted that confirmed cases of influenza upon specimen examination have lessened for the same period. In the national level, the total number of A (H1N1) pdm09 cases was pegged at 9,748 as of March 19. These confirmed cases are only those who were tested from state health laboratories, which does not include those who were diagnosed from private clinics and hospitals.
For the same period, at least two pediatric deaths have been recorded that were linked to influenza infection, bringing the national total number 30 as of March 19. The CDC also noted that for the previous week, around 18 percent per 100,000 individuals, who showed ILI landed in hospitals.
“The increase in the percentage of patient visits for ILI in weeks 51 and 52 (the weeks ending December 26, 2015 and January 2, 2016) may be influenced in part by a reduction in routine healthcare visits during the holidays, as has occurred in previous seasons.” The CDC influenza weekly monitoring report read.
Across the country, at least 10 states showed an elevated proportion of outpatient visits due to the virus at 3.2, which is higher than the national baseline that was pegged at 2.1.
