Mortality rate for influenza in the U.S. in 2022-2023, by age group

The mortality rate from influenza in the United States is by far highest among those aged 65 years and older. During the 2022-2023 flu season the mortality rate from influenza for this age group was around 26.6 per 100,000 population. The burden of influenzaThe impact of influenza in the U.S. varies from season to season, but in the 2022-2023 flu season there were an estimated 31 million cases. These cases resulted in around 360,000 hospitalizations. Although most people recover from influenza without requiring medical treatment, the disease can be deadly for young children, the elderly, and those with weakened immune systems or chronic illnesses. During the 2022-2023 flu season, around 21,000 people in the U.S. lost their lives due to influenza.Impact of vaccinationsThe most effective way to prevent influenza is to receive a yearly vaccination at the beginning of flu season. Flu vaccines are safe and can greatly reduce the burden of the disease. During the 2022-2023 flu season vaccinations prevented around 2,479 deaths among those aged 65 years and older. Although flu vaccines are usually cheap and easily accessible, every year a large share of the population in the U.S. still does not get vaccinated. For example, during the 2021-2022 flu season only about 37 percent of those aged 18 to 49 years received a flu vaccination.

美国流感死亡率之高，首当其冲者莫过于65岁及以上的老年群体。在2022-2023年流感季节，该年龄段的流感死亡率约为每10万人26.6例。流感在美国的影响随季节而异，但在2022-2023年的流感季节，估计有3100万病例。这些病例导致约36万次住院。尽管大多数人无需医疗治疗即可康复，但对于年幼儿童、老年人和免疫系统受损或患有慢性疾病的人群，流感疾病可能致命。在2022-2023年的流感季节，美国约有21,000人因流感而丧失生命。疫苗接种的影响：预防流感的最有效方法是在流感季节开始时接种年度疫苗。流感疫苗安全可靠，可以显著减轻疾病的负担。在2022-2023年的流感季节，疫苗防止了65岁及以上人群中的约2,479人死亡。尽管流感疫苗通常价格低廉且易于获取，但每年仍有相当一部分美国民众未接种疫苗。例如，在2021-2022年的流感季节，仅约37%的18至49岁人群接种了流感疫苗。
