Tridemic

"We are potentially going into what people are calling a 'tripledemic,' or a 'tridemic,'" warned Orange County health officer Dr. Regina Chinsio-Kwong, who on Monday declared a health emergency amid a surge in RSV cases.

With some news outlets breathlessly warning of a potential "tridemic" – a possible simultaneous surge of Covid, influenza and RSV – the Biden administration has announced a new six-week campaign to encourage Americans to get boosters in anticipation of the holidays.

The current rise in Covid-19 cases is one leg of a triple threat – a "tridemic," a "tripledemic" or a "trifecta," as some news organizations are calling it – along with a bad flu season and an RSV outbreak hitting mainly children.

A triple threat of viruses has some health officials warning about a "tridemic" this winter season as influenza, COVID-19 and respiratory syncytial virus (RSV) surge at once.
