Flu activity is down slightly from last week across the U.S, with no states reporting widespread influenza cases. The level of activity will fluctuate through the remainder of flu season, as cold winter temperatures may worsen conditions once again.

All influenza cases reported to the government`s Centers for Disease Control were the 2009 H1N1 viruses, also commonly referred to as the "swine flu." Four deaths were attributed to the 2009 H1N1 virus while one death was associated with the influenza "A" virus.

No widespread activity was noted in the U.S., with regional influenza activity noted in six states, Alabama, Georgia, Maine, New Jersey, New Mexico and Virginia. This is up slightly from last week`s count of five regional influenza activity states.

Meanwhile, local activity was reported in the Puerto Rico and nine states, with sporadic activity in 31 states, the District of Columbia, and Guam.

Nebraska, Idaho, Montana and the U.S. Virgin Islands reported no influenza activity this week.

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.
