Flu cases are on the rise across the United States, with health experts warning that symptoms may soon follow holiday gatherings. Recent data from the Centers for Disease Control and Prevention (CDC) indicates that approximately 15 percent of lab tests are returning positive for influenza, doubling from the previous week.
Current Trends in Flu Cases
In Texas, the situation mirrors national trends, with nearly 20 percent of lab tests showing positive results, also a significant increase from the week before. This rise in influenza cases has prompted health officials to advise caution, particularly as the nation approaches the peak of flu season. According to Dr. Linda Yancey, an infectious disease specialist at Memorial Hermann, “We’re barreling towards the peak of flu season.”
Symptoms and Timing of Illness
Individuals exposed to the flu virus may begin to experience symptoms relatively quickly. A blog entry from CLS Health outlines that symptoms such as sudden fever, chills, body aches, and sore throat may develop as soon as one day after exposure. By the weekend, peak illness typically occurs, marked by cough, fatigue, and dehydration. Dr. Yancey notes that while some may feel better by early next week, lingering symptoms like a mild cough and fatigue could persist.
“Keep in mind, you may experience something different,” said Dr. Yancey. “There are people who could be exposed and get sick the next day, while others may not show symptoms for up to three weeks.”
Flu Shot Timing and Recommendations
For those who attended holiday gatherings and are now experiencing symptoms, Dr. Yancey cautions that it may be too late to benefit from a flu shot. “It takes about two weeks to get the full benefit from the vaccine,” she explained. Despite this, she still encourages individuals to get vaccinated, as flu season extends until March and the vaccine offers approximately 70 percent protection against this season’s strain.
Advice for Those Diagnosed with the Flu
The Houston health department reports that nearly 60 percent of detected flu cases are in children aged 5 to 17. If individuals test positive for the flu or suspect they have contracted it, experts recommend staying home and prioritizing rest. “Listen to your body. It will tell you what it needs,” Dr. Yancey advised.
In addition to resting, CLS Health experts recommend considering antiviral medications if taken within 48 hours of exposure, which can shorten recovery time by as much as two days.
As flu season unfolds, staying informed and taking preventive measures can help mitigate the spread and impact of the virus.
