Fri Dec 27 11:20:00 UTC 2024: ## COVID-19 Cases Rise Nationally as Holiday Travel Begins

**Washington D.C.** – A surge in COVID-19 cases is looming just as Americans prepare for holiday travel and gatherings, according to the Centers for Disease Control and Prevention (CDC). Data from the CDC’s National Wastewater Surveillance System shows a significant increase in COVID-19 virus levels nationwide during the week ending December 14th, rising from low to moderate levels. This increase is particularly concerning as it coincides with a time when people are more likely to gather indoors, increasing the risk of transmission.

Over 40% of U.S. states currently show high or very high levels of the virus in wastewater. Public health experts warn this is an early indicator of a potential large winter wave, mirroring patterns seen in previous pandemic surges. One expert estimates that one in 64 Americans are currently actively infectious. The risk of exposure at a family gathering of 10 people, with no testing or isolation, is estimated to be as high as one in eight.

While other COVID-19 indicators remain low, the wastewater surveillance system provides an early warning system, detecting viral presence even before individuals show symptoms or seek medical attention. The increase is evident across the Midwest, Northeast, and South regions, with only a slight decline observed in the West.

Increased levels of influenza A are also being detected in wastewater, highlighting the risk of multiple respiratory illnesses this season. Experts urge vigilance, recommending preventative measures such as handwashing, vaccination, and mask-wearing to mitigate the risk of infection. While both COVID-19 and influenza share some symptoms, the timing of symptom onset and contagiousness varies slightly between the two.

The CDC emphasizes the importance of awareness and proactive measures to protect public health during this period of increased viral activity. With holiday travel and indoor gatherings peaking, experts stress the importance of preventative measures to safeguard against infection.
