Medical experts are warning Long Islanders about a "tripledemic" of highly contagious viruses as loved ones are set to gather for the holidays.
Cases of the flu, COVID-19 and RSV continue to spread across the country.
Doctors at Northwell Health say they've recorded 9,000 flu cases this season out of patients they've tested.
Doctors also say there has been a 30% increase in positive COVID-19 cases since Thanksgiving, and RSV cases are also surging.
"The children's hospital emergency department has seen 40% great volume and the hospital, both the intensive care and the regular patient floors have been operating at about 105% to 115%," said Dr. Matthew Harris of Northwell Health.
Doctors say the vaccination rates for both the flu and COVID-19 are low and that fewer people are masking and social distancing.
They recommend getting tested for respiratory illnesses before attending holiday gatherings and to consider wearing a mask if there are going to be a large number of people.
Anyone traveling is recommended to get updated vaccines, cleaning surfaces and to test frequently.
