BATON ROUGE, La. (BRPROUD) — The flu and respiratory syncytial virus (RSV) are on the rise in Louisiana, and children are at risk of showing symptoms of high fever.

When should parents take their child to the doctor for fever?

Ochsner Baton Rouge Pediatrician Dr. Brannon Perilloux said there is no specific answer.

“If the child’s temperature is at 101, and they’re running around the room, you don’t need to treat it,” said Dr. Perilloux. “But if it’s 100.5 and the child is miserable, by all means, treat it – not only for the child, but for the parent, too.”

Dr. Perilloux said fever is a healthy response to infection, but parents shouldn’t ignore fevers if they last more than two or three days.

“The amount of viral load in the body at that point in time is reflected in the elevated temperature,” he said. “So, when the infection is decreasing, generally speaking, fever drops with it.”

RSV infections typically occur during the winter and early spring and can last four to six months in temperate climates, according to the Louisiana Office of Public Health. Symptoms can include fever, runny nose, cough and sometimes wheezing.

Walgreens is reporting that Louisiana has snagged the top spot for the highest flu activity nationwide, according to its flu index.

Adults and children can receive their flu shot at Ochsner Baton Rouge from 8 a.m. to 2 p.m. Saturday, Oct. 29. For more information, click here.
