The number of flu cases continues to decline across the U.S. as the number of states reporting widespread and regional activity decreases. Even so, the virus and its symptoms have been unusually deadly over the past 15 weeks, with 7.0 percent of all deaths last week attributed to it.

Only five states are reporting local activity while 30 states reported sporadic flu activity, says the Centers for Disease Control and Prevention. Fifteen states are reporting no activity last week.

Every week throughout the flu season, WeatherBug will provide updates on the latest flu outbreaks.

The CDC recommends that high risk groups, which include the elderly and children less than 23 months of age, get vaccinated on a yearly basis.

In addition to vaccines, there are other things that can be done to minimize your risk for contracting the flu:

• Avoid close contact with those who are sick.
• Avoid exposing others when you are sick. Stay home from work or school if you are exhibiting symptoms.
• Cover your mouth and nose when sneezing or coughing.
• Wash your hands frequently.
• Avoid touching your eyes, nose or mouth.
