Flu cases are on the rise across the United States, prompting health experts to issue warnings as the nation approaches the peak of the flu season. According to the latest data from the Centers for Disease Control and Prevention (CDC), approximately 15 percent of laboratory tests are returning positive for the flu, a significant increase from the previous week. In Texas, the situation is even more pronounced, with nearly one in five lab tests showing positive results.
Understanding Flu Symptoms and Timing
As the flu spreads, individuals who attended holiday gatherings may soon find themselves reaching for tissues. Dr. Linda Yancey, an infectious disease specialist at Memorial Hermann, explained that flu symptoms can develop quickly. In a recent blog post by a doctor at CLS Health, it was noted that individuals exposed to the virus might begin to feel symptoms as soon as one day later. These early symptoms could include sudden fever, chills, body aches, and a sore throat. By the weekend, many will experience peak illness characterized by cough, fatigue, and dehydration.
Dr. Yancey emphasized the variability in symptom onset, stating, “You’re going to have people at each end of the distribution spectrum. Some could be exposed and get sick the next day, while others may not show symptoms for three weeks.”
Flu Shot Timing and Recommendations
For those who suspect they have contracted the flu after holiday gatherings, it may be too late to benefit from the flu vaccine. Dr. Yancey noted, “It takes about two weeks to get the full benefit from the vaccine.” While she still advocates for vaccination, particularly as flu season lasts until March, she stresses that immediate vaccination in the face of symptoms will not provide protection.
Health experts recommend that individuals who test positive or suspect they have the flu should prioritize rest and hydration. “Listen to your body. It will tell you what it needs,” Dr. Yancey advised. “If you’re thirsty, drink. If you’re tired, sleep.”
Additionally, taking antiviral medication within 48 hours of exposure can significantly reduce recovery time by up to two days. This guidance is particularly pertinent, as recent data from the Houston health department reveals that nearly 60 percent of detected flu cases are among children aged 5 to 17.
As the flu season intensifies, staying informed and taking proactive health measures is essential. For ongoing updates regarding flu trends and health recommendations, follow health news sources and local health departments.
