(CNN)–The highest levels of flu-like activities were reported in the South and Southeast, including Alabama, Louisiana, Virginia and North Carolina.

To keep up the awareness about personal responsibility of preventing flu spread, the National Foundation for Infectious Diseases has launched a public education campaign reminding Americans to cover their sneezes and to practice good hygiene.
