Israel detects case of 'flurona' in unvaccinated pregnant woman

Flu cases were at historic lows during last year's season as schools shut down and workplaces went remote, but with a resurgence of influenza, concerns about a "twindemic" caused by "flurona" are high. 

Israel recently confirmed what is believed to be one of the first documented cases of an individual infected with both the flu and COVID-19

An unvaccinated pregnant woman tested positive for both illnesses last week at the Beilinson Hospital in Petah Tikva, the Times of Israel reports.

"The disease is the same disease. They’re viral and cause difficulty breathing since both attack the upper respiratory tract," Arnon Vizhnitser, the director of the hospital's gynecology department, told the newspaper.

Flu has traditionally been America's biggest infectious disease threat, accounting for 600,000 to 800,000 hospitalizations and 50,000 to 60,000 deaths on average every year. 

Dr. Anthony Fauci warned in October 2020, before the first flu season that coincided with the COVID-19 pandemic, that "there’s considerable concern as we enter the fall and winter months and into the flu season that we’ll have that dreaded overlap." 

But those fears never materialized as flu cases nationwide dropped to the lowest levels in decades.

Hospitalizations for influenza are higher now than they were last year though, as 1,825 individuals were admitted to hospitals with the flu nationwide in the week that ended Dec. 25, according to the CDC.

Houston pediatric hospitalizations have now surpassed the peak number of patients from the Delta surge, according to Texas Children's Hospital. This comes as kids head back to the classroom.

Just one child died during last year's flu season, but two children have already died this year, according to the CDC. 

Two years ago, 199 children died from the flu, while 144 died the year before that.
