It was good news for most Americans Thursday as officials released that the dreaded swine flu was only widespread in four states.
Swine flu was widespread in seven states the previous week. Reported infections were on the decline since they peaked in late October, when 48 states reported high levels of sickness.
The increasing availability of the swine flu vaccine, with more than 118 million doses now available, helped contribute to the nationwide decline, said the CDC. Despite the lessening of cases, people should still get vaccinated because there could be another wave of H1N1 infections this winter.
