2017–2018 United States flu season

2017–2018 United States flu season was a notable period of widespread influenza activity across the United States that occurred from late 2017 through early 2018. The season was characterized by a high severity level with a high number of cases, hospitalizations, and deaths.

Overview

The 2017–2018 flu season was one of the most severe in recent years. The Centers for Disease Control and Prevention (CDC) reported that the season was the first to be classified as high severity across all age groups. The season was notable for the high impact on both children and adults aged 65 and older.

Strains

The dominant strain during the 2017–2018 season was H3N2, a subtype of Influenza A virus. This strain is known for causing more severe illness, especially in children and older adults. Other strains, including H1N1 and Influenza B, were also reported.

Impact

The 2017–2018 flu season had a significant impact on public health. The CDC reported a high number of outpatient visits, hospitalizations, and deaths due to the flu. The season also had a high impact on workplaces and schools, with many reporting high levels of absenteeism due to illness.

Prevention and Response

The CDC and other health organizations recommended annual flu vaccination as the best method of prevention. Despite this, the overall effectiveness of the flu vaccine during the 2017–2018 season was estimated to be lower than average. In response to the severe season, public health officials emphasized the importance of preventive measures such as hand washing and staying home when sick.
