Flu cases are on the rise across the United States, prompting health experts to caution that symptoms may develop quickly after exposure, particularly following the recent holiday gatherings. According to the most recent data from the Centers for Disease Control and Prevention (CDC), approximately 15 percent of laboratory tests are returning positive for the flu, a figure that has doubled compared to the previous week.
Dr. Linda Yancey, an infectious disease specialist at Memorial Hermann, noted, “We’re barreling towards the peak of flu season.” In Texas, the situation appears particularly concerning, with nearly 20 percent of lab tests yielding positive results, also double from the week before.
Understanding Flu Symptoms and Timing
Health experts emphasize that individuals may not need to wait long to experience flu symptoms after exposure. A blog post from a physician at CLS Health indicates that symptoms can manifest as soon as one day following exposure. Common initial signs include sudden fever, chills, body aches, and a sore throat. By the weekend, individuals may experience peak illness characterized by cough, fatigue, and dehydration.
Dr. Yancey explained the variability of flu symptoms, stating, “Keep in mind, you may experience something different. There are people who could be exposed and get sick the next day, while others might not show symptoms for three weeks.”
The Importance of Vaccination
For those who may have been exposed during holiday gatherings, Dr. Yancey advises that it may be too late to receive the flu shot for immediate protection. “It takes about two weeks to get the full benefit from the vaccine,” she said. Despite this, she continues to recommend vaccination, noting that flu season lasts until March and the vaccine offers approximately 70 percent protection against the virus this season.
For parents, it is noteworthy that data from the Houston health department shows that nearly 60 percent of detected flu cases involve children aged 5 to 17. If you suspect you have contracted the flu, health officials recommend staying home and resting. Dr. Yancey advises, “Listen to your body. It will tell you what it needs. If you’re thirsty, drink. If you’re tired, sleep. Just give your body a chance to recuperate.”
Additionally, experts recommend antiviral medications, which can significantly reduce recovery time if taken within 48 hours of exposure. These medications can shorten the duration of flu symptoms by up to two days, providing important relief during peak flu season.
