Boston is experiencing a significant increase in flu cases this year, with numbers rising sharply in December. Health officials are urging everyone to take precautions, especially as more people gather indoors during the winter months.

Alarming Statistics

  • 114% jump in flu cases in the first two weeks of December.
  • 44% increase in emergency room visits related to the flu.
  • Children aged 5 to 17: 217% increase in infection rates.
  • Children under 5: 83% increase in cases.

This early surge is concerning, as last year's flu season didn't peak until February. The current numbers are nearly seven times higher than they were at the same time last year.

New Flu Strain and Vaccination Rates

A new strain of the flu virus, called "subclade K," is spreading globally, including in the U.S. However, health officials say this strain isn't more severe than others. Only 30% of Boston residents have gotten their flu shot so far this season.

  • Get vaccinated: Vaccines are one of the best ways to protect yourself and others.
  • Practice good hygiene: Wash your hands regularly and stay home when you're sick.
  • Increase ventilation: Improve airflow in homes.
  • Wear masks: Especially around high-risk individuals, including young children, older adults, pregnant women, and those with chronic illnesses or weakened immune systems.

COVID-19 Update

Boston is also monitoring COVID-19 levels, which have increased by 909% in the past two weeks. However, these levels are still relatively low compared to previous trends. The city has been hosting free vaccine clinics across different neighborhoods, with over 2,500 people vaccinated so far. These clinics will continue throughout January, and more information can be found on the city's website or by calling the Mayor's Health Line.
