More Americans are seeking medical care for flu than at any time since the “swine” pandemic of nearly a decade ago, say US health officials.
Thirty-seven children have died and nearly 12,000 patients have been admitted to hospital nationwide.
The outbreak could surpass 2014-15 when 34 million Americans fell ill, says the US Centers for Disease Control and Prevention (CDC).
In that season, 710,000 people were admitted to hospital and 56,000 died.
The director of the CDC, Dr Daniel Jernigan, said thousands of people were going to doctor’s offices and emergency rooms to seek treatment for flu-like symptoms.
