DOVER (WPVI) --It may be spring, but the flu virus is still going around.
Officials in Delaware saw three more flu-related deaths in the past few weeks.
And overall, the number of cases this season is the highest it's been in more than a decade.
The latest deaths in Delaware were in three different counties, all senior citizens with other health problems.
With the season lingering, you have to keep your guard up.
Even in April last year, there were several flu-related deaths.
Right now, Pennsylvania is reporting lower numbers but still with widespread flu activity.
Delaware continues to see cases, and New Jersey reports lower flu activity this week.
To protect yourself, make sure you're washing your hands frequently.
And if you're at high-risk for complications or you have young kids or elderly parents, if they have flu-like symptoms, call their healthcare provider.
