This year’s flu season has reached a 15-year high, with significant strain on hospitals, schools, and healthcare systems nationwide. According to experts, several factors contribute to this unusually high number of cases.
The primary cause is the recent cold winter that drove people indoors, increasing close contact and making it easier for the virus to spread. The US may also be experiencing an “immunity gap” due to reduced exposure to flu and other viruses during the pandemic.
However, the biggest contributor behind this year’s surge in flu cases is likely low vaccination rates. As of February 1, only 146.5 million doses of the vaccine were administered, a decline of 7% compared to last year.
To protect yourself from the flu, experts recommend good hygiene, such as frequent handwashing with soap and water. Vulnerable individuals should consider additional precautions like wearing high-quality face masks in indoor public spaces.
Maintaining a healthy lifestyle by getting enough sleep, eating nutritious foods, and staying active can also strengthen your immune system and reduce the risk of infection. Getting the flu shot is the most effective way to prevent severe disease and hospitalization.
According to experts, getting vaccinated can significantly reduce the severity of the flu, even in mismatched years or with lower vaccine effectiveness. The Centers for Disease Control and Prevention (CDC) reports that vaccination rates are at their lowest level in years, with fewer than half of Americans currently immunized.
By understanding the causes of this year’s unusually high flu season and taking preventive measures, individuals can reduce their risk of infection and protect themselves and their loved ones from severe illness.
