Experts have warned that this season's new 'super flu' is showing signs of resurgence after finally slowing last month. The cases have largely been driven by H3N2 subclade K, nicknamed 'super flu,' which has been linked to longer lasting, more severe symptoms than previous variants. South Carolina is battling super flu alongside a historic measles outbreak, which has infected 847 people since October 2025, 20 of whom were fully vaccinated against the disease. Health officials warn this year's virus season is far from over amid as slight uptick in positive tests. Several schools across the country have had to close or move to remote learning due to high flu activity.
