Medical experts are warning about a triple threat of contagious viruses this winter, leaving some parents concerned.

The warning surrounds influenza and respiratory syncytial virus (RSV) at a time when COVID-19 cases are expected to rise.

There was a long line at a COVID-19 booster shot clinic in Hoboken on Tuesday, filled with people hoping to knock out at least one of these viral threats.

There were many children on the line getting their second booster shot. Their parents say they have either already gotten or are about to get a flu shot as well.

“With [my daughter] being back at school and with everything going on right now – more strains coming out – we want to be as safe as possible,” says Liz Bloom.

Additional COVID-19 strains, fears of the flu and an uptick in RSV in young children ahs some medical professionals warning about a possible “triple pandemic.” While health experts believe most cases will be mild, the three illnesses could overwhelm hospitals. The experts are encouraging everyone to get their flu shots and COVID boosters as soon as possible.

The New Jersey Health Department says that flu activity is low in New Jersey currently. But the online dashboard also indicates that doctor and emergency room visits associated with the flu-like illnesses are higher this week than last week – and higher than this same week last year.

Doctors say New Jersey residents can get the COVID vaccine and a flu shot at the same time. There is no vaccine for RSV.
