Doctors are reporting an uptick in patients with respiratory syncytial virus, or RSV, which they say acts like a common cold but is more dangerous.

RSV can affect anyone, but East Meadow pediatrician Dr. John Zaso says it's especially concerning for the elderly, premature infants and children under age 1.

"It looks like a horrendous cold, and then it progresses into the deeper symptoms," Zaso says.

Michelle Cona brought in her 5-month-old son Vincent, who tested positive for RSV. Zaso says he's out of the "danger zone" but will still need to be monitored.

Doctors say RSV can be easily diagnosed -- all it takes is a quick swab of the nose. They say RSV is spread by contact with surfaces.

There's no cure for the viral disease. Doctors say the problem is that there's no good specific treatment.

Zaso says a shot for premature babies can help protect them during peak RSV season.

Anyone with questions should contact their personal doctor.
